GI Hot dip Galvanised zinc-coated steel coils sheet 1.5mm G60/G90 for Metal Deck ASTM A-653 and ASTM A-924
The galvanized steel sheet in structural, commercial and full hard quality, is a product that combines the characteristics of mechanical resistance of the steel and the resistance to the corrosion generated by the zinc. It is utilized in the industry of cooling, construction, automobile and metallurgical in general.
Metal Deck overview
Metal deck changes the traditional construction of the floor structure, which consists of a pre-formed steel plate (steel bridge deck) and a concrete slab cast monolithically on top of the plate to form a composite steel floor.
The advantages of galvanized steel decking
1. Anticorrosion.
After hot-dip galvanization, the galvanized steel floor decking sheet has better anticorrosion.
2. High strength tensile.
The galvanized steel floor decking sheet has better anti-resistence than other metal building.
3. Environment friendly.
There is no pollution for using the galvanized steel floor decking sheet.
4. Cost-saving.
Using little money to maintain a long time by using the Galvanized steel floor decking sheet.
5. Free of maintenance.
You don’t need to do some further operation after installing the Galvanized steel floor decking sheet.
