Metal Bar Grating – Lightweight Structure, Good Ventilation, Light Transmission & Excellent Slip Resistance

Metal bar grating is a mesh-like panel composed of load-bearing flat bars and cross bars arranged at specified intervals, secured by welding or press-locked methods. It features a robust structure, excellent ventilation and light transmission, as well as superior slip resistance and durability. This product is widely used in industrial platforms, stair treads, walkways, drainage trench covers, equipment maintenance passages, railings and guardrails, as well as architectural facades. Depending on application needs, it can be made from carbon steel, stainless steel, or aluminum alloy, with surface treatments such as hot-dip galvanizing or coating to enhance corrosion resistance and extend service life.
