product technology
The production of steel grid plate mainly has two kinds of machine pressure welding and manual production. Machine pressure welding using high voltage resistance pressure welding machine, through strong electric welding power and liquid pressure to press the transverse rod into the flat steel, to ensure that the solder joint is strong, stable and strong. Handmade, on the other hand, is relatively flexible and suitable for various special needs.

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.
