Frequently Asked Questions:
Q: What distinguishes SPTE grade tinplate?
A: SPTE denotes standardized specifications for tin coating weight, hardness, and surface characteristics ensuring batch-to-batch consistency.
Q: Can I request custom dimensions?
A: Yes, thickness (0.12-0.50mm) and width (600-1200mm) are fully customizable with MOQ of 5 tons.
Q: How does T5 hardness benefit industrial applications?
A: T5's higher tensile strength (390-480MPa) resists deformation in high-stress environments like automotive brackets.
Q: What packaging is used for export?
A: Weatherproof wooden pallets with edge protectors, typically 2-3 tons per 20ft container.
Q: Are samples available?
A: Free A4-sized samples provided within 7 working days.
Q: What's the lead time for bulk orders?
A: 15-25 days after deposit confirmation, depending on customization.
Q: How is corrosion resistance ensured?
A: Through controlled tin coating thickness (2.8-11.2g/m²) and optional passivation treatment.
Q: Do you provide technical support?
A: Our metallurgy team offers application-specific grade selection guidance.
With certifications audited to international standards and exports reaching 5 continents, we guarantee material consistency that reduces your production rejects by up to 18%.
