Products Description

 

Steel grating consists of thin metal sheets arranged in a complex grid or lattice pattern. This structure can be perforated or assembled. It is widely used in various industries, including stairways, platforms, scaffolding, and protective enclosures. Steel grating can be manufactured using processes such as expansion, perforation, forming, and welding.

Steel grating was originally developed to enhance airflow in underground environments, thereby preventing heat buildup and maintaining cleanliness.

Considerations for steel grating include thickness, rod size, pattern opening, load-bearing capacity, and environmental conditions at the installation site. Steel grating is versatile and available in standard sizes or custom-made to meet unique application requirements. Customization is often required to meet the specific needs of individual installations.
