Description

The press welded steel grating,requested by the customers,is made of load flat steel bar and cross bars,placed horizontally and vertically,and at an equal pitch apart,by welding with 200-ton hydraulic resistance automatic welding equipment,then cutting,punching and banding ends .

 

Applications

-Rotation ways, channels, and platforms for pump rooms and engine rooms in various ships;

-flooring in various bridges such as railway bridge sidewalks, over-bridges across the street;

-platforms for oil extraction sites, car washing sites and air towers;

-fencings for car-parks, buildings and roads; drainage trench covers and drainage pit covers for highways.

 

Manufacturing process

Steel grating bar is made by the world first-class Italian ORSOGRIL 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.


Surface process of grating

Hot-dipped Galvanizing

Normally, hot-dipped galvanizing will be carried out after end welding process. When the thickness of bearing bars is not less than 5mm, the weight of average Zinc Layer will not be less than 610g/m2.

When the thickness of bearing bars is less than 5mm, the weight of average Zinc Layer will not be less than 460g/m2. The quality and requirements after hot-dipped galvanizing are according to the standards of GB/T13912.
