Process of steel grating

 

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.

Advantage:

  • No corrosion traps around joints
  • High strength to weight ratio
  • Allows shaping without loss of strength
  • Available plain or serrated
  • Allows passage of heat, light, water and ice.

 

 

The applications of steel grating:

  • -Fencings for car-parks, buildings and roads; drainage trench covers and drainage pit covers for highways;
  • -Flooring in various bridges such as railway bridge sidewalks, over-bridges across the street;
  • -Rotation ways, channels, and platforms for pump rooms and engine rooms in various ships;
  • -Platforms for oil extraction sites, car washing sites and air towers;
