1 Product Parameters：

2 Product Characteristics：

Material width: 1000mm 
Material thickness: 0.8mm-1.2mm 
Raw material requirements: galvanized sheet
Raw material 
Continuous hot dip galvanized steel plate is mainly used, and aluminum zinc plated steel plate is rarely used 
Reason of raw material chosen:
Galvanized steel plate mainly has galvanized sheet and continuous hot galvanized sheet, galvanized sheet is only on the surface of the steel plate on a layer of coating, corrosion resistance is poor, cold bending may appear peeling phenomenon; And continuous hot dip galvanized, zinc can be immersed into the surface of the steel plate, the formation of Zn-Fe alloy, corrosion resistance is better, so it is recommended to use continuous hot dip galvanized steel plate. 
According to the provisions of the national standard "Guide to Zinc and aluminum Overlay for corrosion resistance of Steel structures" GB/T 19355-2003, the aluminized zinc plate is in direct contact with concrete, and the contact surface should be passivated to prevent the chemical reaction between aluminum and concrete and destroy the bond performance of concrete and molded steel plate. In theory, it is possible to passivate the surface of aluminized zinc plate, but in practice, the cost increases a lot and it is difficult to do so. Therefore, it is not recommended to use aluminium-zinc plate as profiled plate for composite floor slab.
