High quality hot dip galvanized steel grating(factory)
1.Introduction of galvanized steel grating
1>material:carbon steel or stainless steel
2>cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.
3>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 we can produce high quality gratings with firm welding,smooth surface and high strength.
4>Surface process: there are three types:hot-dipped galvanized ,electro galvanized and spraying brushing and soaking.
2.Specification of galvanized steel grating
(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.
