1.material:
carbon steel or stainless steel
2.Steel grating
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.
3.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.
4.Specification of grating steel
1)The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated type and I-Shape type
2)Bearing bar pitches can be 12.5, 15, 20, 30, 30.16, 32.5, 34.3, 40, 60mm, of which 30mm & 40mmare recommended.
3)Cross bar pitches can be 38, 50, 60,100mm, of which 50mm & 100mm are recommended.
