China Manufacture Prime Hot Rolled Dipped Zinc Galvanized Steel Coil
What is Galvanised steel used for?
Galvanized steel, in particular, is often what is used in modern “steel frame” buildings. Galvanized steel is also used to create structures like balconies, verandahs, staircases, ladders, walkways, and more. Galvanized metal is the ideal choice if your project will live outside after it's done.
