Painted Pressure Locked Grating Carbon Steel Long Working Lifespan
Press Lock Grating Description:
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.
4>Surface process of steel grating:hot-dipped galvanized,electro-galvanized ,painting. 95% people choose hot dip galvanized because its anti-acid and alkali corrosion capacity range is from PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.
