Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.

Steel bar grating has a vast amount of uses ranging from flooring and stairs to bridges and sewage drain covers. It is a smart choice for flooring and stairs in work areas where slipping and falling are a major concern, such as industrial plants, waste-water treatment facilities, or manufacturing operations. The open design makes bar grating the best option for areas that require the passage of light. It also works well for projects that require fast, easy fabrication and installation.
