What is Electrolytic Tinplate?
Electrolytic tinplate is a kind of tinplate. It is made by electroplating 0.3-0.8mm thin cold-rolled steel plate with pure tin to get a smooth and even surface.
The ETP is tempered to transform the soft and brittle electrolytic tinplate into a tough steel plate with good hardness, toughness, and shape stability.
What are the Typical Electrolytic Tinplate Uses?
- Electrolytic tinplate is one metal material that has significant corrosion resistance to water and acid. It’s widely used in packaging for food and beverage, especially for cans.
- You can have your packaging cans in various sizes and shapes, such as round, square, oval, rectangular, and more.
- Large-sized electrolytic tinplate is widely used to make construction materials, such as bricks, tiles, profiles, steel windows and doors, kitchen cabinets, steel rooms, and other such products.
- Electrolytic tinplate is also used to make automotive structural parts such as engine blocks, oil filters, gaskets, and cylinder heads.
- Small-sized electrolytic tinplate is used in food packaging (such as canned food), daily products, and chemical products packaging (such as washing powder).
- In the electronic industry, electronic tinplate is used for electrical equipment products and electronic parts. These include capacitors, condensers, resistors, and coils (coils usually have a cover of electrolytic tinplate), set-top box, digital cameras, mobile phone shell, computer casings, etc.
- Aerosol cans, paint cans, hardware products, and chemical containers are also made from electrolytic tinplate.
What are the Main Electronic Tinplate Properties?
Main electrolytic tinplate properties include;
- Excellent oxidation resistance, corrosion resistance, and mechanical properties
- High strength, lightweight, high brightness, and a smooth surface with good decorative effect
- It has excellent solderability, hot formability, and cold formability
- Low production prices and readily available raw material because of recycling.
- Good weldability and plasticity. It can be welded by most of the general welding methods, such as arc welding, resistance welding, or laser beam welding
- Easy to install and repair, high insulation properties, low heat conductivity, and good dielectric strength
- It is also easy to recycle and can reduce environmental pollution.
What are Electronic Tinplate Specifications?
Electronic tinplate may be specified according to the steel base, temper, surface finish, annealing type, and thickness.
The base material for making the electrolytic tinplate is usually SUS304/SUS316L/SUS430 stainless steel sheet or cold-rolled steel sheet. Its thickness ranges are between 0.3-0.8mm. The steel base determines the hardness of ETS.
Tinplate with a thickness of 0.2mm-0.3mm is mainly used for printing and packaging boxes, airtight cooking pots, and other containers. The tinplate with a thickness above 0.3mm can be used for roofing, car body, container tank, etc.
The hardness of the tinplate is determined in the temper mill during cold rolling. Double reduced ETP is of thinner gauge, lighter, and very strong. The intended use of the ETP will guide you in choosing the right temper tinplate.
The Rockwell Hardness test is standard in designating temper grades according to ASTM A623 standard specifications
|Rockwell Hardness Test -HR 30T Scale|
|Single reduced (SR)||Double reduced (DR)|
Electrolytic tinplate, as a kind of thin metal plate, belongs to metal finishing products. Therefore, its crucial quality indicators are the color, texture, and structure of the surface.
The surface finish of electrolytic tinplate is divided into four levels: bright shiny, bright and rough, matt and dull.
The International Standard (ISO898-1) defines annealing in three types: Soft tempering with no surface treatment, soft tempering with shiny chromium-plated on one side, and medium treatment hard tempering type, plated with shiny chromium on one side.
The thickness of the tinplate plays a crucial role in determining the tinplate type. ETP has a thickness range of 0.15-0.36mm. The thinner the tin plate, the weaker it gets and can easily be damaged.
Electrolytic tin plate specifications summary:
|Temper (B. Annealed and C. Annealed)||T1-T5, DR8 and DR10|
|Thickness||0.15-0.36mm with a tolerance of +/-0.01mm|
|Width||300-1050mm with a tolerance of 0-3mm|
|Diameter (inside coil)||420-508mm|
|Surface finish||Mirror, Silver, Matte, Bright, Stone|
How is Electrolytic Tinplate Produced?
Outline of Electrolytic tinplate production
Electrolytic tinplate is made by cold rolling thin steel sheets and then coating both faces with electrolytic tin. A process called electroplating produces it. Tin is deposited on a steel sheet from a dilute solution of tin salts.
The steel is the cathode. The anode is made from carbon (graphite) shaped into a large cylinder.
An electrical current is passed through the solution from the anode to the cathode and onto the steel. Tin dissolved in water forms an electrolyte around each grain of graphite.
As the current passes through, tiny particles of tin are deposited on each grain of graphite.
The production process of electrolytic tinplate should be carried out in the workshop in a clean environment to ensure the quality of electrolytic tinplate products.
How many Types of Base Steel are there for Electrolytic Tinplate manufacturing?
There are three basic types of base steel for the manufacture of electrolytic tinplate; MR (Medium-carbon), L (Low-carbon), and MC (Medium-low carbon).
These steels are known as “basic types” because their compositions are fixed by Japanese Standards (JIS).
Carbon is generally 0.10 – 0.20% in MR steel with 0.25% max; while it is 0.05-0.15% in L and MC steels with 0.30% max for both. Manganese level should be between 0.3 – 0.6%, while sulfur composition should be 0.05% maximum.
MR steels have high corrosion resistance and good anti-stress cracking properties. L steels have stronger corrosion resistance than MR steels and relatively low anti-stress cracking properties.
MC steels have good corrosion resistance (except for MC70 type) and low-to-moderate stress corrosion cracking resistance.
Another difference between these steel substrates is the maximum service temperature and their different mechanical properties.
The grade of base steel used for producing electrolytic tinplate varies as required by a customer for their specific applications.
It is also possible to produce electrolytic tinplate from other types of steel such as CR, SMR, MS, and MSS.
How does Static Annealing vs Continuous Annealing compare for Electrolytic Tinplate Production?
Annealing of tinplate sheets is indispensable. It makes the tinplate soft, enhances plasticity, and improves its overall properties. It also enables tinplate to be readily formed by rolling during the manufacture of cans.
Static annealing is a process that provides the tin content of the electrolytic tinplate to a specified range on heating. Because of its low time efficiency, static annealing is used primarily for cold-rolled strips.
Continuous annealing is a process that provides the tin content of the electrolytic tinplate by partial melting. Because of its high time efficiency, continuous annealing equipment is used primarily for hot rolled plates and coils in plate mills.
Compared with continuous annealing, static annealing uses less energy. Obviously, it saves more heat than continuous annealing.
To calculate the continuous annealing cooling rate, you don’t need to consider the time factor because the temperature is constant. In contrast, to calculate the cooling rate for static annealing, you need to consider the time factor applicable to heating and cooling.
With the continuous annealing line, the products will be evenly heat-treated (annealed) by the induction heating plate.
The temperature of the induction heating is stable, and the heat treatment time is short.
However, because of the different thermal conductivity of the product and induction plate, the heat will concentrate on the surface of the ETP product and cause non-uniformities. As a result, it may affect product quality.
In a static annealing line, a roll of tinplate is directly placed into a high-temperature furnace to complete heating treatment. The heat is distributed along its surface area, so tin content uniformity can be guaranteed.
What is the Structure of Electrolytic Tinplate?
Electrolytic tinplate (ETP) is very low-carbon steel coated with tin. The electrolytic method is used as a coating process for steel.
Anodes deposit onto the hot steel sheet a very thin layer of copper (usually 0.02mm).
When an electric current passes through the copper coating, it dissolves and deposits onto the steel surface.
This acts as the bond between steel and the tin layer.
This forms a layer of copper on the steel sheet and the required thickness of tin coating onto the metal surface.
A protective film of lacquer may be applied to protect against corrosion in storage sheds.
Tin will give an appealing bright finish. It is non-toxic and excellent for food and beverage packaging.
Its solderability properties make it easy for dorm different shapes and sizes of packaging material.
How is Electrolytic Tinplate different from Tin Plated Steel?
Tin plated steel is steel coated with a thin layer of tin. The coating can be applied by electrolytic deposition or dipping the steel substrate in a bath of molten tin.
ETP, on the other, is strictly produced by the electrolysis process.
Tin-plated steel has a thin layer of tin on its surface. Therefore, the electromagnetic properties are not as good as the electrolytic tinplate.
The tin layer of electrolytic tinplate is electroplated on a rough surface. The tin thickness can reach up to 3.0 – 4.0g/m2.
It has good electromagnetic shielding and high mechanical properties (ductility and impact strength).
Under the same steel sheet grade, ETP has the advantage of higher strength and higher electrical conductivity than tinplate sheets.
Electrolytic tinplate is the tin-plated steel with a high tin content, developed in the early 20th century to avoid iron-tin corrosion.
The electrolytic tinplate has higher quality requirements than tin-plated sheet because of its thickness.
It’s widely used in lids and bases for cans because electrolytic tinplate has better anti-corrosion performance against acid and alkali liquid than a plain sheet.
What are the Two Types of Electrolytic Tinplate?
The two types of electrolytic tinplate are:
Single Reduced ETP
A single layer of thermally tin-plated steel (camellia or non-camellia) is drawn, rolled, followed by second steel rolling. The thickness of the final product is typically less than 6 µm. Single reduced ETP has a little lower mechanical properties than double reduced one.
Double Reduced ETP
Double reduced ETP is usually thinner than single reduced ETP. It follows the same production process as the SR ETP. With this, the tinplate is subjected to a second cold reduction with lubrication.
This improves the mechanical strength as well as other properties of the double reduced tinplate.
What is Soft Double Reduced Tinplate?
Soft Double Reduced tinplate (SDRE) is soft, durable tinplate of low carbon steel.
Its average chemical composition is: C ≤ 0.19%, Si ≤ 1.10%, Mn ≤ 1.00%, P ≤0. Its chief characteristics are softness and flexibility.
This type of ETP has excellent formation performance because of its special cold rolling production process. It also features excellent corrosion resistance and formability.
SDRE is suitable for many industrial packaging applications. It can be used to make rectangular steel containers (including milk cartons), cans, drums, tins, and another product packaging.
Note that this type of ETP has no surface protection coatings but can be coated with various lacquer or enamel finishes. It can be recycled into anode-grade electrolytic tinplate without any pre-treatment.
What are the Surface Treatment Options for Electrolytic Tinplate?
When purchasing electrolytic tinplate, you can choose from several surface treatment options to customize the ETP to your specific needs.
Our surface treatment options for electrolytic tinplate allow you to create highly unique designs and finishes that are sure to stand out in the crowd.
Chemical passivation is a surface treatment process that is used to increase the corrosion resistance of tinplate.
In this technique, the surface of the ETP is immersed in an acidic electrolyte solution. The anode, made of a material with a low affinity for tin (such as iron), is placed in an earthed tank containing the electrolyte.
The cathode, made of tin plate, is immersed in the electrolyte solution and suspended above the anode through a chain called “tin fish”.
The surface of the electrolytic tinplate is coated with a thin layer of chromium oxide.
When the tinplate is in contact with air, the chromium oxide on the surface forms a protective film of chromium oxide (CrO) and prevents corrosion.
This process is called electrochemical passivation.
Electrolytic tinplate has the characteristics of smooth surface, bright color, and good corrosion resistance.
There are two kinds of electrolytic tinplate; high-chromate electrolytic tinplate and low-chromate electrolytic tinplate.
High-chromate electrolytic tinplate contains over 1.2% chromium, while low-chromate electrolytic tinplate contains less than 0.1% chromium.
Sandblasting is forcing air through a nozzle onto the surface of an object. The air is sprayed with sand or some other abrasive substance.
This abrasive material causes small pits to form on the object’s surface, which increases its roughness.
The abrasive particles are held close to each other by a high-velocity stream of air, resulting in very high finish quality and consistency.
Electrolytic tinplate is an excellent candidate for sandblasting as it can be applied to even small parts with thin walls.
Sandblasting enhances the appearance of ETP while increasing its strength.
When should you Consider Electrolytic Tinplate Coil vs Electrolytic Tinplate Sheet?
Electrolytic tinplate coil
The significant difference between the electrolytic tinplate coil and the plate is that the coil is coiled into a roll.
At the same time, the sheet is stamped on the flat surface.
The thickness, width, and length of the coil are usually customized according to customer preference.
The tinplate sheet, on the other hand, is all set before production.
ETP coil can be embossed or printed on the surface before the galvanizing process. This option is not available with the tinplate sheet.
Suppose your particular application requires the easy handling or the packaging flexibility that a coil brings to the table.
In that case, that’s where you’ll want to go. But sometimes, a sheet is more convenient to work with.
For example, if you need a part with a curved edge or a complex shape, we recommend choosing a sheet.
Also, if you’re in the middle of an intricate fabrication process and don’t want your metal interrupted by joints, choose an ETP sheet.
What is the Difference Between Equality Coated ETP and Differentially Coated ETP?
Electrolytic tinplate has two surface treatments; equally coating and differentially coating.
Equally, coating means that the thickness of the coating on both sides of the electrolytic tinplate is the same.
The effect is low out-gassing, more excellent color stability, cleaner surface and, good corrosion resistance.
Differentially coated for ETP means that the thickness of the tin coating on both sides is different. Only one side of the tinplate sheet is coated with a high-quality chrome coating.
The other side is rolled steel with no coatings.
When you need to make your products look more professional, we recommend differentially coated ETP for your manufacturing process.
Equally coated ETP and differentially coated ETP have been developed to meet the needs of diverse users.
Equally coated ETP is widely used in packing, food cans, containers for liquid chemicals, pharmaceuticals, and other fields which require corrosion protection with a good appearance.
Differential coated ETP has different coating thicknesses on either side to avoid the concentration polarization phenomenon.
It is used in pressure vessels, condensers, and chemical reactors.
How do you Determine Tin Coating Weight for Electrolytic Tinplate?
The weight of coating materials for electrolytic tinplate is expressed in g/m2. The tin coating weight is a function of the content of Sn in the tin plate, the thickness layer, and the basis weight.
Tin coating weight in electrolytic tinplate is determined by the combined effect of the tin coating thickness and tin coating content.
The coating weight is a critical component in determining the tinplate’s corrosion resistance.
The average tin coating weight of electrolytic tinplate is from 2 to 5 microns (μm).
If end-use requires higher weather and rust resistance, choose ETP with a heavier coating weight.
Light coating weight ETP is used in applications that do not need high resistance. It is important to choose according to specific product use.
Are Deviations in Coating Weights for Electrolytic Tinplate Allowed?
Yes, deviations in coating weights for electrolytic tinplate are allowed.
The coating weight tolerance for electrolytic tinplate is 3%. Deviations and tolerances are specified in the respective standard.
Deviations are defined as the difference between the declared coating weight and the actual weight of a test sample.
If the deviation exceeds 3%, then the tinplate’s quality is determined through testing per EN 10208.
What are the BIS Specifications for Marking Differentially Coated ETP?
BIS stands for Bureau of Indian Standards (BIS) specifications (based on IS 1993/ISO11949) for marking differentially coated ETP.
The standard requires marking to comprise 1mm wide parallel lines and the distance between the lines indicating the coating masses.
As per the standard, coating wise line spacing for differentially coated ETP is as below:
|Designation||line spacing (mm)|
|D8.4/2.8||25 -alternate with 12.5|
|D8.4/5.6||25 -alternate with 12.5|
|D11.2/5.6||37.5 -alternate with 12.5|
What is the Recommended Hardness for Electrolytic Tinplate?
The recommended hardness for electrolytic tinplate is HRC 58-60 degrees. The tinplate can be easily deformed if the hardness is less than HRC 58 degrees.
The hardness of the tinplate is measured by Rockwell Hardness Cone.
Temper is the hardness of a metal. Temper grades are a way of describing how soft or hard tool steel is.
The steel with the highest temper grade is the most rigid
The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest.
Tempers 5 and 6 are known as tool steels because they’re used to make saw blades and files.
Does Electrolytic Tinplate have a Tensile Rate?
The word “tensile” is derived from the Latin “tensus”, which means “stretched.”
The term refers to measuring how much an object can be stretched before it breaks or is deformed permanently.
Tensile rate is an essential property of tinplate. It describes the stress required to elongate one square inch of sheet one-thousandth of an inch compared to its original length.
Electrolytic tinplate has a tensile rate that ranges between 350psi and 1000psi.
What are the recommended Quality and Reference Standards for Electrolytic Tinplate?
Electrolytic tinplate is produced to high-quality standards.
During and after production, the material is continually tested to ensure that it conforms to the required quality, performance, and safety standards.
Regulatory standards that ETP should adhere to include:
- GB/T13453-2008: Electrolytic tinplated steel sheet for container Standard.
- ISO14963-2006: Steel sheets and plates for containers electrolytically coated with metallic zinc.
- ISO 11949 -1995: standard specification for cold reduced (CR) electrolytic tinplate.

Electrolytic tinplate is Eco-friendly and recyclable material product.
What are the Requirements of Electrolytic Tinplate for Food Packaging?
Electrolytic tinplate for food packaging has to meet certain conditions.
ETP for food packaging can only be produced in factories strictly complying with the requirements of the Food and Drugs Administration (FDA), which are mainly as follows:
- The factory must be equipped to carry out all the processing stages, from electrolytic tinplate production to tinplate packaging.
- In both electrolytic tinplate production and printing, each process must be carried out in an independent building.
- This is to eliminate any chances of pollution or cross-contamination either from previous processes or the environment.
- All areas containing chemicals must be labelled clearly and separated from areas where food is handled.
Also, the FDA requires that materials used to be approved for food contact. The materials should be BPA and phthalate-free.
Other Requirements of Electrolytic Tinplate for Food Packaging:
Tinplate for food packaging must have passivation. The package has to be corrosion and rust-proof; resist oxidation, rusting, or corrosion caused by moisture and acidic foods.
If the storage temperature is higher than 50 degrees, ETP packaging must have high thermal stability.
It’s required that the material be coated with an immiscible organic layer.
This will help effectively prevent oxygen, water, and gases from penetrating the tin surface onto the food contents.
Excellent sealing performance, be easy to clean and maintain are other requirements of ETP food packaging.
Electrolytic tinplate has excellent surface processing performance such as polishing, brushing, embossing, printing, and coating.
This will help in the labelling and branding.
The packaging material should have high wear resistance, good mechanical strength, and hardiness.
It’s also required that the ETP packaging be sustainable and recyclable.
What are the Main Features of Electrolytic Tinplate for Tin Cans making?
Electrolytic tinplate is widely used to make tin cans because it has good mechanical properties such as good formability and high thermal conductivity.
ETP cans are widely used for food, beverage, daily chemicals, and all kinds of other tin packaged goods.
The use of tin cans will help improve the quality of products, such as preserving freshness and tastiness.
This material has excellent surface quality, plasticity and bending performance.
It can be readily cold rolled without cracking and can be formed in different sizes and shapes.
Electrolytic tinplate’s excellent sealing property and lightweight also make it an excellent option for tin cans making. ETP cans are also easy to produce and cheap both to produce and use as the end product.
What is ‘Base Weight’ in Relation to Electrolytic Tinplate?
In the tinplate industry, ‘base weight’ is the minimum thickness of tinplate in micron that can be rolled into coils.
The base weight is also referred to as the ‘minimum gauge’ or simply ‘the gauge’.
The higher the base weight percentage, the thicker the metal is. Electrolytic tinplate has a “base weight” of 65-85 gsm and thicker by cold rolling.
How does Bright (B) vs Stone (R) vs Silver (S) finish for Electrolytic Tinplate Compare?
The bright finish is used to produce food and beverage cans, aerosols, and automotive parts.
It is a dull, non-reflective finish that increases durability.
Stone finish is used to produce pet food cans, aerosols, and other industrial applications where a dull grey appearance is acceptable.
The surface has non-scratch properties.
The silver finish has a bright, attractive, metallic appearance. It is used in packaging high-quality, well-recognized consumer products such as electronic products, beverages, and foods.
What are the Maximum Shipping Weight and Transport Dimensions for Electrolytic Tinplate?

- Transport volume per unit length of base: 0.08 m3
What are the Packaging Requirements for Electrolytic Tinplate?
ETP packaging example
The requirements for packaging electrolytic tinplate are as follows:
Electrolytic tinplate is very easy to be oxidized, so it is packed in a protective atmosphere.
The packaging process of electrolytic tinplate includes waterproofing, thermal insulation, and film winding.
The finished product shall be wrapped on both sides with plastic film to prevent scratches and deformation during transportation.
It should be packed in standard export seaworthy packing with three internal wooden-barred pallets or two internal wooden-barred pallets and a plasterboard-barred pallet.
The pallet is used as protection to avoid direct contact with the ground.
The packaging should be firm and tight and should meet the requirements of environmental protection.
ETP outer packaging size, marking, and labelling should comply with international standards and technical specifications.
Remember, quality packaging should ensure durability, protection against damage and better storage.
How do you find Electrolytic Tinplate HS Code for Customs Duties and Clearance?
HS code refers to harmonized system tariff. It is used to identify products and determine their applicable tariff during international shipping.
Note that these codes are unique to each product. To find the code for Electrolytic tinplate, you’ll need to search the tariff classification tool. This tool is often found on government websites such as the chamber of commerce, ministry of trade or customs site etc.
Once on the site, just key in the description that is closest to your product, in this case, electrolytic tinplate.
What are the Usage Precautions for ETP?
Keep the following things in mind when using Electrolytic tinplate:
- Electrolytic tinplate is easy to rust and should be stored in a dry place and be used as soon as possible.
- To avoid rust on the surface of ETP, you should use oil. For example, wipe it dry with some oil.
- ETP is soft and prone to scratches during transportation and rough handling. For this reason, precautions should be taken when transporting or handling ETP products.
- The internal surface for Sulphur and alkaline content cans should be painted. Sulphur blackens ETP cans surface while tin dissolves in the alkaline solution.
- Avoid putting electrolytic tinplate products into high-temperature water for a long time.
Is Electrolytic Tinplate Good for Low-Temperature Applications?
Electrolytic tinplate has excellent oxidation resistance and mechanical properties. However, it is not suitable for use under low-temperature conditions.
Tin in the ETP changes its structure and loses adhesion when exposed to temperatures below – 40 degrees C.
