Customer Reviews
Yes we have received the reinforcing mesh and we are pretty happy with the quality. Many thanks! Chris

—— Chris Johnson

I have been ordering powder coated T 316 fly screen mesh from Qijie; unlike others, they never cut orders and always supply quality material to me.

—— Michael Jr. Venida

I had very bad purchasing experience with the previous supplier, for they always postpone shipment time. To my excitement, Qijie is always punctual.

—— Susan Miller

Your product good

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;
