The open mesh steel grating is a flat panel durable metal grate made from carbon steel or stainless steel with a light structure firmly welded together. It is widely used for industrial ladders, decking safety, ventilation ceilings and floors, platform and stair tread protection panels. The open spacing design instead of solid metals allows good ventilation, and easy flow of lighting and heat. The standard sheet size is 1m x 6m standard type (special size and American standard size are also customizable).
