NOT:Steel grating size shoud be as your demand ,different steel grating have  different  loadcarrying capacity,

for example

Bearing bar centers at 20mm: 

This kind of fine mesh steel gratings have strong load ability and also can prevent the access of sundries of 18mm in diameter. This kind of gratings fit for pedestrian deck, walkway and ditch covers which require high security.

Bearing bar centers at 60mm: 

This kind of steel gratings are especially used for mining industries. It can solve the problem that mineral splashing down and stacks on the walkway. This product usually used for mineral miningand processing and it is the best choice for workshop, meeting room and suspended ceiling of stadium in terms of it's light weight.

Galvanized Steel Grating manufacturing process

GalvanizedSteel grating Placed horizontally and vertically, and at an equal pitch apart, by welding with 200ton hydraulic resistance automatic welding equipment then cutting punching and handing ends. 

Galvanized Steel Grating used

Steel Grating product : Stair tread ,Trench cover, Suspended ceiling,Steel ladder etc .

steel grating used in steel grating standards, power factory ,chemical plants,oil refineries,steel plants,paper mills,machinery manufacture,cement plants,municipal works,sewage treatment,the pharmaceutical industry etc.

Galvanized Steel Grating installation method

The galvanized steel gratings should be always firmly attached onto their supports with following methods: 

1. Welding Fixed Suitable for those permanently installed gratings or those which are not to be removed frequently  

2.Use of Clips and Screws Suitable for gratings that are to be removed frequently.and won't damage the Grating itself.
