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.
4>Surface process of steel grating:Types:hot-dipped galvanized,electro-galvanized ,spraying brushing. 95% people choose hot-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.
5>Attractive appearance:Simple outline.silver colour and modern.
6>Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.
7>Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.
8>Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety and convenient opening.
