Quality Control & Shipping Case
Buyer Concerns (FAQ）
Buyer Concerns
What is the MOQ?
What is the lead time?
Which standards and grades are available?
Can thickness, width and coating be customized?
How are the coils packed and shipped?
Q: How do I choose the zinc coating mass (Z30–Z275)?
A: Z30–Z80 is ideal for indoor cable trays and ducting. For outdoor roofing and high-humidity environments, we recommend Z180–Z275 for 15–25 years of rust resistance.
Q: What are the processing advantages of Normal Spangle GI?
A: Normal spangle features natural zinc crystallization, offering superior surface hardness and 1T–2T bend performance without zinc flaking. Perfect for structural decking, HVAC, and profiling.
Q: How do you prevent white rust during ocean transport?
A: All coils undergo Chromate Passivation/Oiling paired with VCI anti-rust paper and waterproof plastic wrapping to isolate sea moisture during long transit.
Q: What mill certificates and standards do you offer?
A: Compliant with ASTM A653 / EN 10346 (DX51D/SGCC). Every shipment includes EN 10204 3.1 MTC, and we fully support SGS / BV third-party inspection.
