Galvanized Sheet Welded 32x5 Serrated Metal Grating - 30mm Bearing Bar Pitch with 100mm Cross Bar Spacing
Galvanized sheet welded steel bar grating is a durable metal building material designed for walkways, platforms, and industrial flooring applications. The serrated surface provides excellent anti-slip properties for enhanced safety.
Steel grating is manufactured by arranging bearing bars and cross bars in a flat-steel weft pattern, then welding them together using high-pressure resistance welding technology. Additional processing includes cutting, incision, opening, and overlock operations to meet specific customer requirements.
