1.Introduction of hot dip 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 computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.
Ditch cover plate, steel flat pallet, flooring, etc.
Twisted square steel commonly used cross bar.
Steel plate is generally made of carbon steel with hot-dipped galvanizing, can prevent oxidation.Or use stainless steel.
