Stainless steel grating is a metal grid product made by welding stainless steel flat bars at specific intervals and crossbars (or round bars). The manufacturing methods are mainly divided into two types: manual welding and machine pressure welding.
Manual Welding: First, holes are punched in the flat bars, then the crossbars are inserted into the holes and spot-welded.
Gap exists between the crossbars and the flat bars, but this ensures that each contact point is welded, achieving an equivalent melting connection between the flat bars and the twisted steel.
Manually welded steel gratings have higher strength, but their appearance is not as aesthetically pleasing as machine-press-welded ones.
Machine Pressure Welding: A high-pressure resistance welding machine is used. A robotic arm automatically places the crossbars horizontally onto the evenly arranged flat bars.
Through powerful electric welding and hydraulic pressure, the crossbars are pressure-welded into the flat bars, resulting in high-quality steel gratings with strong welds, stability, and high strength.
