Product Details

BOLI Steel grating typically consists of parallel and perpendicular steel bars, with the perpendicular bars welded or locked into place by various methods such as welding, riveting, or swaging. The design of the grating allows for the passage of air, light, and liquids while providing structural support.
Steel grating is extensively used for industrial flooring in factories, warehouses, manufacturing facilities, and industrial plants. Its robust construction provides a stable and safe walking surface for workers while allowing ventilation, drainage, and the passage of light and air.
