1.Surface Process of Gratings:

Hot dipped galvanizing and lacquering

2.Manufacturing Process:

Steel grating 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 welding which is controlled by computer. So we can produce high quality gratings with firm welding, smooth surface and high strength.

3. Features:

Steel gratings have many advantages, such as light weight, high strength, great load-bearing capacity, being economical of material, ventilation and light admission, modern fashion and attractive appearance, anti-slip and safety, easy cleaning and installation, durability.

4.Installation

There are two ways of installation for grating.

*One way is by welding and the other is by installation fastenter. The welding method is suitable for those parts which will be fixed forever, such as platforms for equipments, while the method by installation fastener has the properties of easy to assemble and disassemble and of preventing destroying the zinc layer.

5. Application:

Steel gratings are widely used in various plants at home and abroad, like power plants, chemical plants, oil refinery, iron and steel works, machine factories, paper mills, cement mills, hospitals and food processing factories, etc.

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

* Floorings in various bridges such as railway bridge sidewalks, over-bridges across the street.

* Platforms for oil extraction sites, car- washing sites and air towers

* Fencing for car-parks, buildings and roads; drainage trench covers and drainage pit covers for highway
