Composite steel grating is covered with a layer of checkered plate or steel plate on the steel grating, which has the characteristics of high support strength and closed surface. Generally used for floor panels, etc.

After hot-dip galvanizing treatment, the composite steel grating is prone to warpage and deformation due to thermal effect. In particular, it is difficult to level the galvanized flat steel, so please pay attention to type selection.

Composite steel grating usually adopts steel grating with flat steel spacing of 30mm, 40mm or 60mm as the base plate; The tread plate is usually 3mm thick, but can also be 4mm and 5mm thick.
