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.

19-w-4 Platform Steel Grating Hot Dipped Galvanized Mild Steel Bar Grating

 

Steel grating is usually provided with one of three finishes, bare steel (no finish), painted with one

coat of manufacturers red, black or silver paint, or hot dip galvanized in accordance with ASTM A-123.

Aluminum products are commonly supplied mill finish but they are also available with optional chemically

cleaned or anodized finishes. Due to discoloration that occurs during welding and fabrication, Stainless

Steel grating products typically require secondary finishing

 

Commercial cleaning, passivation or abrasive blasting can provide a uniform matte surface and a bright

stainless finish can be provided by electro-polishing. All grating products can be provided with specialty

finishes including enamel or epoxy paints or powder coating. When considering specialty finishes,

consultation with the coating manufacturer is essential.
