Function of heavy-duty steel grating

Hot Dipped Galvanized Expanded Metal Mesh Drainage Steel Grating Stair Treads Customized

  • 1.Widely used in shipbuilding, harbor, oceanographic engineering, building, paper mills, cement plant, medicine, spinning and weaving.
  • 2.It Is applied in food stuff factory, transportation, municipal administration, parking lot , etc.
  • 3. Also used by various plants such as electric power, petroleum,chemical industry.

High strength and high bearing capacity:

  • Non-slip, anti-corrosion, not easy to deform.
  • High safety performance.
  • Do not accumulate rain, snow and dust.
  • Simple and beautiful appearance.
  • Easy to install and remove to extend the lifespan.
  • Applications of serrated welded steel grating
  • Serrated welded steel grating is widely used as platforms, stair treads, walkaways and floors in industrial, civil and commercial buildings.

Feature Advantage

1).good anti-skipping, used in wet , slipping area, especially the sea oil platform

2).Hot-dipped galvanized,high anti-corrosion, 30years life time, can be used as channel cover with frame, anti-thief, safe and easy to open

3).High strength, and better than cast iron, can be used in wharf, airport and other long span and heavy loading environment.

4).Large hole for drainage, Water leakage area up to 83.3%, it is the best choice of forestair.

5).Good-looking : clean lines, silver appearance, modern idea, save material , save cost; when long span, heavy load, it is cheaper than cast iron.

The applications of steel grating:

  • -Fencings for car-parks, buildings and roads; drainage trench covers and drainage pit covers for highways;
