Hot-dip galvanized steel grating panels for high-rise tower platforms are made by crossing flat steel bars at certain intervals with crossbars, then welded into a steel product featuring square grid patterns in the center. They are primarily used for drain covers, steel structure platform panels, and step plates for steel ladders. The crossbars are generally made of twisted square steel.

Grating panels are generally made ofQ235Low-carbon steel construction with hot-dipped galvanized finish for corrosion resistance. Stainless steel options are also available. The grating panels feature ventilation, lighting, heat dissipation, anti-slip, and explosion-proof properties.

Manufacturing methods of grating panels: machine welding and handcrafted two methods.Machine brazing utilizes a high-voltage resistance brazing machine,The robotic arm automatically places the crossbar horizontally on the evenly arranged flat steel bars.,The crossbar is pressure-welded into the flat steel by means of powerful electric welding power and hydraulic pressure.,Thus, the solder joints are robust.,High-quality grating panels with excellent stability and strength. Handcrafted grating panels are initially punched on flat steel, followed by inserting crossbars into the holes and spot-welding them, resulting in gaps between the crossbars and flat steel.,And it's impossible to weld at every contact point, thus resulting in weak welds.
