1.Steel grating description

Steel grating is also name as metal bar grating,it is made by welding flat steel and bars with certain distances.


2.Common specification
1)Bearing bar pitches may be 15 to 30, 40, 60, 80 and 90mm; Of which 30and 40mm are recommended
2)Cross bar pitch may be 30, 38, 50, 76 and 100mm; Of which 50 and 100mm are recommended


3.Finished
a. Hot-DIP galvanizing. It is the process of coating iron or steel with a thin zinc layer by passing the steel through a molten bath of zinc at a temperature of around 860 F (460 C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbonate, adult grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Galvanized steel is widely used in applications where rust resistance is needed.
b.Painting
c. Untreated.
