Steel Grating

Heavy-Duty Steel Grating | Industrial Bar Grating & Trench Covers

Steel grating, also known as bar grating or metal grating, is a robust structural product made by welding or pressure-locking load-bearing bars with cross bars at regular intervals. Unlike traditional wire mesh, steel grating is designed primarily for heavy-duty applications where strength, durability, and load capacity are critical. The open-grid structure not only provides excellent weight-to-strength ratio but also ensures proper ventilation, drainage, and slip resistance.

Our steel grating products are manufactured from carbon steel, stainless steel, or galvanized steel, and can be customized in terms of bar size, spacing, and surface finish. Hot-dip galvanizing is the most common surface treatment, providing long-term corrosion resistance even in outdoor and marine environments.

Steel grating is widely recognized for its role in industrial flooring, walkways, platforms, stair treads, trench covers, and safety barriers. With superior strength, anti-slip properties, and ease of installation, steel grating has become an indispensable material in industries such as oil and gas, shipbuilding, power generation, construction, and wastewater treatment.
