Construction and Features of Welded Bar Grating

Welded bar grating is constructed through a resistance-welding process that permanently joins the cross rods to the bearing bars. Our welded grating features a unique design with twisted square rods and rectangular bars or I-type bars, offering a strong and secure product. Its high lateral stiffness, facilitated by press-locking, allows it to be used in a variety of special applications.

Moreover, the grating's surface treatments include galvanizing, painting, and powder coating, ensuring corrosion resistance and a pleasing aesthetic. The serrated surface option enhances its non-slip performance, making it safe and secure for various environments.

Specifications and Performance

Our welded bar grating is available in different materials such as low carbon steel and stainless steel, catering to various customer requirements. The bearing bars and cross bars can be notched and have the same height, creating an efficient, high-capacity platform.

Welded bar grating's attractive silver exterior coupled with simple lines reflects modern design trends, making it aesthetically pleasing without compromising functionality.
