Interlocking Steel Grating: Also known as insert steel grating, it is manufactured through processes such as slotting (punching), insert fitting, welding, and finishing, using carbon steel, stainless steel, brass, and aluminum plates of specific dimensions. This interlocking steel grating combines the high strength, corrosion resistance, and maintenance-free features of ordinary steel grating, with the benefits of even and precise assembly, lightweight and exquisite structure, natural harmony, and elegant style. The product is widely used for drain covers, stair treads, and pond covers.

Four types of steel grating can be distinguished: pressed steel grating, heavy-duty steel grating, solid steel grating, and sunshade curtain steel grating, based on different insertion methods and angles.

1. Pressed Steel Grating: After cutting grooves in the bearing flat steel, the crossbar flat steel is pressed and locked into shape. The processing height for standard steel grating production is 100mm. The length of the steel grating is usually less than 2000mm.

2. Heavy-duty grating panels are a type of steel grating product formed by interlocking high-width steel and crossbar steel strips, tightly molded under 1200 tons of pressure. They are suitable for high-span and heavy-load applications.

3. Integrated Steel Grating Panels - The load-bearing flat steel and cross bar flat steel of the integrated steel grating panels have the same height and slot depth, which is half the depth of the load-bearing flat steel. The height of the steel grating does not exceed 100mm. The length of the steel grating is typically less than 2000mm.

4. Sunshade Grating: The load-bearing flat steel of the sunshade grating features 30° or 45° oblique grooves, and the grooved flat steel is locked in place. We can supply grating panels with different spacings and specifications as required, using materials such as ordinary carbon steel, stainless steel, aluminum, etc. The height of the grating panels is less than 100mm.
