1.Steel gratingis 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.
material:carbon steel or stainless steel
cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.
2.Specification of hot dip galvanized steel grating
(1)The shape of bearing bar: Plain type (may be omitted in the
