The crossbars of pressure-locked steel grating are typically made of flat steel with dimensions of 20×5 /12 ×5/12 ×3 (or other specifications), which is pressed into the load-bearing flat steel under high pressure. The nodes between the flat steel are automatically locked by the compressive force generated through deformation, and can be manufactured from ordinary carbon steel, aluminum alloy, or stainless steel.Due to the vertical interlocking structure of standard press-locked steel grating, it achieves a superior aesthetic appearance compared to standard press-welded steel grating, making it particularly suitable for use as shelving platforms, grid windows, partition bars, light transoms, and indoor ceilings. Additionally, the steel grating with this structure offers enhanced lateral (width direction) load-bearing capacity and effectively prevents the tilting instability issue that can occur with large-sized load-bearing flats, making press-locked steel grating especially suitable for heavy-duty applications.
