Frequently Asked Questions (FAQ)
What are the standard dimensions available for your galvanized coils?
Our galvanized coils are available in thickness ranges from 0.2mm to 5.75mm, and widths ranging from 600mm to 1500mm to fit various industrial applications.
What is the difference between hot-dip and electro-galvanized coils?
Hot-dip galvanized coils feature a thicker zinc layer which provides superior rust resistance. Electro-galvanized coils have a thinner, smoother zinc coating, making them ideal for high-precision applications requiring a superior surface finish.
Which industries benefit most from using galvanized steel coils?
They are widely applied in construction (roofing and steel structures), home appliances (exterior panels), automotive manufacturing (chassis and body parts), agriculture (greenhouses), and various industrial ventilation or duct systems.
What are the typical mechanical properties of your galvanized steel coils?
Our coils offer a tensile strength between 300MPa and 600MPa, a yield strength between 200MPa and 400MPa, and a zinc coating thickness ranging between 10g/m² and 275g/m² depending on your requirements.
Do you supply materials other than galvanized coils?
Yes, as a global supplier, we also deliver comprehensive steel solutions, including steel strands, cold-headed standard parts, and special alloy wire materials to support your production needs.
