Galvanized steel grating inside also includes composite steel grating, composite steel grille is the combination of pattern plate and steel gratings, generally used on the platform.
When composite steel grids are subjected to design loads, their deformation deflection should not be greater than 1/200 of the span, and the maximum should not exceed 10 mm.
In addition to meeting the above requirements, all platforms shall comply with the following requirements:
1. When the design load value is * 1.5, the composite steel grid plate will not produce permanent deformation.
2. When the design load value is *3.0, the composite steel lattice plate will not crack. The design requirements under special load conditions are agreed by both the supplier and the demander.
