Shandong Sino Steel Co., Ltd. takes pride in offering high-quality Industrial Tinplate Coil 0.18mm x 1000mm, specifically engineered for the production of crown caps and closures. Our product delivers consistent thickness accuracy, excellent formability, and a smooth surface finish, ensuring optimal performance in high-speed stamping processes. As a trusted manufacturer with over 6 years of export experience, we combine precision manufacturing with rigorous quality control to meet the demanding requirements of the packaging industry.
This tinplate coil is manufactured using prime cold-rolled steel substrate with a uniform electrolytic tin coating, providing superior corrosion resistance and solderability. The 0.18mm gauge is ideal for deep-drawing applications, while the 1000mm width allows efficient material utilization in crown cap production lines. Whether you need standard bright finish or matte surface, we offer flexible customization to match your specific cap manufacturing needs.
Key Features & Benefits
- Precise Thickness Control: ±0.01mm tolerance ensures uniform material flow, reducing scrap and downtime during stamping.
- Excellent Surface Quality: Bright or matte finish with minimal pinholes, providing a clean base for printing and lacquering.
- High Formability: Temper range T2-T5 allows deep drawing without cracking, ideal for complex crown cap shapes.
- Corrosion Resistance: 2.8/2.8 g/m² tin coating (standard) protects against rust and maintains food-grade safety.
- Consistent Width: ±0.5mm width accuracy ensures smooth feeding into progressive dies.
- Customizable Coil Dimensions: Inner diameter 508mm, outer diameter up to 1200mm, and weight per coil from 3 to 5 tons.

Frequently Asked Questions (FAQ)
1. What is the minimum order quantity (MOQ) for this tinplate coil?
Our standard MOQ is 1 coil (approx. 3–5 tons). For trial orders, we can accept smaller quantities upon negotiation. Please contact our sales team for details.
2. Can you supply coils with different tin coating weights?
Yes, we offer customizable tin coating weights ranging from 1.1/1.1 g/m² to 5.6/5.6 g/m². The standard for crown caps is 2.8/2.8 g/m², but we can adjust based on your requirements.
3. Are free samples available for testing?
Yes, we provide free samples (1–2 kg cut pieces) for quality evaluation. The customer pays for the shipping cost. Samples can be dispatched within 3–5 working days after request.
4. How do you ensure the thickness tolerance is maintained?
We use advanced automatic gauge control (AGC) systems during rolling and inline thickness measurement. Each coil is inspected with a micrometer at multiple points, and a mill test certificate is provided with shipment.
5. What packaging is used for export shipment?
Coils are packed in a standard eye-horizontal orientation with steel pallets, edge protectors, and multiple layers of waterproof paper and plastic film. Optionally, we can also use wooden crates or steel frames for extra protection.
6. Can this tinplate coil be used for twist-off or other closures, not just crown caps?
Absolutely. The 0.18mm thickness and temper range make it suitable for a variety of closure types, including twist-off caps, lug caps, and press-on caps. We recommend conducting a trial run with your specific tooling.
7. What is the typical lead time for an order?
For standard specifications, lead time is 15–20 working days after order confirmation and deposit. Customized orders may take 20–30 working days. We also maintain a buffer stock of popular sizes for quick shipment.
8. Do you have any certification for food contact safety?
Our tinplate is manufactured with food-grade materials. While we hold ISO9000 and ISO19011:2000 certifications, we can also provide a compliance declaration with the EU regulations (EU 1935/2004) upon request. Please check with your local regulations for specific requirements.
