Quality Control & Shipping Case
Buyer Concerns (FAQ）
Q1: GL vs GI: What is the main structural difference?
A: GL steel features a 55% Al-Zn alloy coating, which provides superior barrier protection and thermal reflectivity compared to pure zinc-coated GI steel.
Q2: What surface treatment options are available for GL coils?
A: We offer chromated, oiled, dry, and anti-fingerprint (AFP) resin coatings (transparent, blue, or green) based on your storage and processing requirements.
Q3: How does the Zero Spangle Galvalume Steel coating perform during bending and roll forming?
A: Our GL steel offers excellent structural stability and uniform coating adhesion, making it suitable for standard roll-forming and press-forming operations.
Q4: What is your Minimum Order Quantity (MOQ)?
A: Standard MOQ is one 20ft container (~25 tons). You can mix 2–3 thicknesses or widths in one load.
