Quality Control & Shipping Case
Buyer Concerns (FAQ）
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: Is Big Spangle GI identical to Normal Spangle in corrosion resistance?
A: Yes, both offer identical corrosion resistance under equal zinc mass, but Big Spangle features a traditional decorative pattern.
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.
