CE Standard Customizable Galvanized 60%-85% Open Area Drain Steel Grating
Steel bar grating, known for its high strength and robust structure, is manufactured from carbon steel, aluminum, or stainless steel. Depending on the production method, steel grating can be categorized into four types: welded bar grating, press-locked grating, swage-locked grating, and riveted grating. Based on surface design, it is available in both smooth and serrated options. With a wide range of styles and sizes, steel grating serves versatile applications in everyday life, including stair treads, walkways, platforms, flooring, trench covers, wheeled equipment, security screens, and heavy-duty constructions.
