galvanized steel drain grate/decorative metal grate/stainless steel mesh grate/metal catwalk decking/bar grating supplie
Galvanized steel drain grate is made of bearing bar according to certain spacing and cross bar isarranged , through pressure welding machine or manual welding to turn it into a middle with square lattice is a kind of steel products , steel grid plate is mainly used to do the ditch cover plat ,steel flat pallet , steel ladder step plate , etc. the cross bar is generally used with twisted square steel .
carbon steel or stainless steel
2>cross bar pitches
24-200mm,of which 50mm,76mm and 100mm are recommended.
is made by the world first- class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer.so we can produce high quality gratings with firm welding,smooth surface
and high strength.
4>Surface process of gratings:
there are three types:hot-dipped galvanized ,
electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.
Hot dipped galvanized, cold dipped galvanized, spray painting,
dip anti-rust oil, can prevent oxidation.
Flat type, serrated type, I shape type(According to requirement made different protective treatment).
