What is Steel Grating?

Steel grating (galvanized high heel trench grating) is manufactured by arranging bearing bars and cross bars in a flat-steel weft pattern. The components are welded together using high-pressure resistance welding technology, then processed through cutting, incision, opening, and overlock operations to meet specific customer requirements.

Packaging & Handling

Steel grating is typically stacked and secured with two pieces of square wood placed on both upper and bottom sides. Four to six M10 long bolts penetrate through the gratings and are screwed together for secure bundling. This packaging method is suitable for efficient loading and unloading using forklifts and cranes.
