Galvanized Steel Grating Description
Steel grating is also called steel frame lattice or steel grid plate. 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, industrial and so on.

Applications
Steel grating has been widely used in all walks of life worldwide. It is mainly used as platform plates, ditch covers, stair treads, and building ceilings. The products feature high strength, light structure, high load-bearing capacity, and convenience for loading. The hot-dipped zinc coating provides excellent anti-corrosion resistance.
Applications include:
- Rotation ways, channels, and platforms for pump rooms and engine rooms in various ships
- Flooring in various bridges such as railway bridge sidewalks, over-bridges across the street
- Platforms for oil extraction sites, car washing sites, and air towers
- Fencings for car-parks, buildings, and roads
- Drainage trench covers and drainage pit covers for high strength applications
