ASTM A653 Galvanized Sheet Coil For Construction
Product Introduction
ASTM A653 galvanized coil is a product that complies with the American Society for Testing and Materials (ASTM) A653 standard. It is made by hot-dip galvanizing, which is to immerse the cold-rolled steel coil in a boiler containing molten zinc so that the zinc layer adheres to the surface of the steel plate. There are also types with zinc-iron alloy coating (hot-dip galvanizing annealing treatment).
This galvanized coil has excellent corrosion resistance and can extend its service life. It has good strength and durability, excellent processing performance, and good weldability and formability.

FAQ
Q: What is ASTM A653?
A: A standard for hot-dip zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) steel sheets, used for corrosion resistance in construction, automotive, and appliances.
Q:What does "G60" or "G90" mean?
A: Coating weight (oz/ft²):
G30 = 0.30 (light duty)
G60 = 0.60 (general use)
G90 = 0.90 (harsh environments)
Q:What are surface finish options?
Regular spangle (visible crystals)
Minimized/zero spangle (smooth for painting)
