Dimensions Material thickness: Common thickness of 2mm, 3mm, 4mm, 5mm and so
on. Different thicknesses of steel grids have different bearing
capacities and are suitable for different application scenarios. Size: Width is common 100mm, 150mm, 200mm, 250mm, 300mm, etc. The
length is made according to customer requirements, and the general
length is between 1 meter and 6 meters. The dimensions of steel
grids must be determined according to the actual application
scenario. Grid plate spacing: usually millimeters (mm) as a unit, such as
25mm, 30mm, 40mm and so on. The spacing affects the bearing
capacity and anti-skid performance of the steel grid. Load grade: According to the carrying capacity is divided into
different grades, such as A15, B125, C250, etc., representing
different carrying capacity. The selection must be based on the
load requirements of actual applications.
