Shandong Sino Steel Co., Ltd., a professional manufacturer established in 2018 with a factory spanning 10,000–30,000 square meters, proudly presents our Annealed Tinplate Strip 0.22mm–0.35mm Full Hard Temper for Precision Stamping. This product is engineered to meet the rigorous demands of high-speed stamping processes, offering excellent dimensional stability and consistent mechanical properties. With an annual export value of US$2.5 million to US$5 million and a dedicated team of 101–200 employees, we ensure every coil meets the highest quality standards for industries ranging from food packaging to electronics.
Our tinplate strip is produced using advanced annealing and temper rolling techniques, resulting in a full hard temper that delivers superior strength and rigidity. The thickness range of 0.22mm to 0.35mm is specifically optimized for precision stamping applications where tight tolerances and repeatable forming are critical. Whether you require shallow drawn parts, closures, or complex stamped components, this material provides the ideal balance of hardness and formability.
Key Features & Technical Specifications
- Consistent Thickness Tolerance: ±0.01mm across the entire strip width, ensuring uniform material flow during stamping.
- Full Hard Temper: Typically 80–90 HR30T hardness, providing excellent dimensional stability and resistance to buckling.
- Excellent Surface Quality: Bright or matte finish available, with low surface roughness (Ra ≤ 0.4μm) to minimize tool wear.
- High Ductility: Despite its hardness, the material maintains adequate elongation (≥2%) for moderate forming without cracking.
- Tin Coating Uniformity: Controlled coating weight (2.8–11.2 g/m² per side) ensures corrosion resistance and solderability.
- Customizable Width: Available from 600mm to 1250mm, slit to your exact requirements.
- Clean Edge Finish: Free of burrs and slivers, reducing downtime in progressive dies.
- RoHS Compliant: Tin coating is free from harmful substances, suitable for food contact applications.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for this tinplate strip?
A: Our MOQ is typically 5 metric tons per thickness/size. However, we can accommodate smaller trial orders for new customers. Please contact our sales team for details. -
Q: Can I get the strip in custom widths and coil weights?
A: Yes, we offer slitting services to meet your exact width requirements (from 600mm to 1250mm). Coil weights can be customized up to 5 tons per coil. -
Q: How is the product packaged to prevent damage during transit?
A: Each coil is wrapped with moisture-proof paper, plastic film, and steel strapping, then packed in wooden crates or pallets as per export standards. Additional anticorrosion treatment is available upon request. -
Q: What is the typical lead time for this material?
A: For standard specifications, lead time is 15–20 days after receipt of deposit. Custom orders may require 25–30 days. We can expedite urgent orders based on availability. -
Q: Does this tinplate strip meet food contact safety standards?
A: Yes, our tin coating is produced with food-grade tin and complies with EU and US FDA regulations for direct food contact. We can provide a compliance certificate upon request. -
Q: What is the difference between full hard temper and other tempers for stamping?
A: Full hard temper (T4) offers the highest strength and rigidity, ideal for shallow stamping where minimal forming is required. For deeper draws, we recommend a softer temper (T2 or T3). Our technical team can help you select the right temper for your application. -
Q: Do you provide samples for testing before bulk order?
A: Absolutely. We can supply free samples (A4 size or small coil) for evaluation. You only need to pay the shipping cost. Contact us with your request. -
Q: What quality certifications do you hold?
A: We are certified to ISO9000 and ISO19011:2000 management systems. Our in-house laboratory conducts routine tests for thickness, hardness, coating weight, and surface quality.
