In today’s fast-paced industrial world, materials that combine durability, corrosion resistance, and visual appeal are in high demand. Tin-plated steel strip coils are among the most versatile and widely used materials in packaging, automotive, electronics, and consumer goods industries. These coils combine the structural strength of steel with the anti-corrosive and solderable properties of tin, making them ideal for applications where hygiene, preservation, and surface quality are essential.
This article provides a detailed overview of tin-plated steel strip coils, their key characteristics, industrial applications, manufacturing process, and how to source them in bulk—especially from leading producers in China.
What Are Tin-Plated Steel Strip Coils?
Tin-plated steel is a low-carbon steel strip that has been coated on both sides with a thin layer of tin. This coating provides excellent corrosion resistance, enhances appearance, and improves solderability. It is typically supplied in coils for easy transport, storage, and processing.
The tin coating is applied using an electrolytic plating process, ensuring even coverage and strong adhesion. The base steel is usually cold-rolled for a smooth finish and consistent mechanical properties.
Key Features of Tin-Plated Steel Strip Coils
✔ Corrosion Resistance
The primary advantage of tin plating is its ability to resist rust and oxidation, especially in humid or food-grade environments.
✔ Food Safety and Hygiene
Tin is non-toxic and approved for contact with food and beverages, making these coils ideal for packaging applications like cans, bottle caps, and containers.
✔ Excellent Formability
Thanks to the ductility of both tin and low-carbon steel, tin-plated coils can be easily stamped, deep drawn, or bent without flaking or cracking.
✔ Superior Surface Finish
The tin layer provides a bright, reflective surface that is not only functional but also aesthetically appealing.
✔ Solderability
Tin-plated steel is widely used in the electronics industry because it provides a solderable surface without requiring additional preparation.

Applications of Tin-Plated Steel Strip Coils
1. Food and Beverage Packaging
The most common application of tin-plated steel is in the packaging industry, where hygiene and preservation are critical. It’s used for:
-
Food cans and tinplate containers
-
Beverage bottle caps
-
Aerosol spray cans
-
Cookie tins and decorative boxes
2. Electronics and Electrical
Its excellent solderability and surface conductivity make it ideal for:
-
Electrical terminals and connectors
-
Battery components
-
Shielding parts and EMI enclosures
3. Automotive Components
Some interior or under-the-hood components benefit from the anti-corrosion layer of tin-plated steel.
4. Household Goods
Used for manufacturing items like:
-
Metal trays
-
Kitchen utensils
-
Lids and covers
-
Decorative metal containers
5. Industrial Packaging
Drums, lids, and closures that require resistance to moisture and corrosion also rely on tin-plated coils.
Types of Tinplate Finish
-
Bright Finish: Mirror-like surface, preferred for printed packaging.
-
Matte Finish: Dull, low-reflection surface for paint or label adhesion.
-
Stone Finish: Textured, suitable for high-end packaging.
-
Silver Finish: Electrolytic tinplate with a premium shine.
Tin Coating Weights and Selection
The amount of tin deposited on the steel surface is measured in grams per square meter. Coating weights are chosen based on corrosion resistance needs and application type. Common tin coatings include:
-
2.8/2.8 g/m² (balanced coating for both sides)
-
5.6/2.8 g/m² (heavy one side, standard the other)
-
11.2/11.2 g/m² (for extreme corrosion resistance)
Why Source from China?
China is one of the largest producers and exporters of tin-plated steel strip coils, with major hubs in Shandong, Jiangsu, and Shanghai. Chinese manufacturers offer:
✔ Cost-Effective Bulk Supply
Due to economies of scale and advanced facilities, Chinese tinplate is competitively priced without compromising on quality.
✔ Export-Ready Products
Suppliers offer international packaging, documentation (COC, Form A, CE), and logistics support.
✔ Customizable Orders
Thickness, width, tin coating weight, and coil dimensions can be tailored as per buyer requirements.
✔ Global Certifications
Most manufacturers meet ISO 9001, RoHS, REACH, and SGS standards.
Shipping Terms: FOB & CIF Options
When sourcing tin-plated coils from China, most suppliers offer standard international shipping terms:
📦 FOB China Port (Free on Board)
The supplier is responsible for transporting the goods to the Chinese port (e.g., Shanghai or Qingdao) and loading them onto the ship. The buyer manages ocean freight, insurance, and import clearance.
🚢 CIF Destination Port (Cost, Insurance, Freight)
The supplier covers the cost and insurance of shipping the goods to your destination port (e.g., CIF Los Angeles, CIF Hamburg). This is ideal for international buyers seeking a hands-off approach.
Quality Control and Inspection
When sourcing tin-plated steel from China, request the following:
-
Mill Test Certificate (MTC)
-
Third-party inspection reports (SGS/BV)
-
Sample coils or sheets
-
Batch photos and packaging confirmation
Buying Tips
-
Define your required thickness, width, temper grade, and coating weight clearly.
-
Always request a pre-shipment inspection.
-
Compare FOB and CIF pricing to see which suits your logistics setup better.
-
Choose suppliers with a proven export history and certifications.
