Welded Galvanized Steel Trench Grating 40x5mm Serrated Bars with 460g/m² Zinc Coating for Industrial Platforms
Galvanized steel grating features mild carbon steel construction with hot-dipped galvanized surface treatment for superior corrosion protection. These heavy-duty structural elements provide reliable performance in demanding industrial environments.
Gratings serve as effective filters for drains and air vents, blocking large solids while allowing liquid and air movement. Widely used in offshore oil rig platforms, refineries, walkways, and industrial facilities where strength and durability are critical.
