Feature:
1). High strength, light structure: solid grid pressure welding structure has advantages of high load, light structure, easy installation, etc.
2). Fine appearance, durable in use: hot zinc dipping surface treatment makes it own fairly good corrosion resistance, bright and beautiful surface.
3). Good ventilation, lighting, thermal, anti-explosion, and anti-skid performance.
4). Prevent dirt deposition.

Application: It is widely used for platform, aisle, trestle, drain cover, manhole cover, steel ladder, fence, and guardrail in the fields including petrochemical, power station, sewage treatment plant, mechanical manufacture, mechanical and electrical equipment, paper mill, cement plant, pharmacy, food processing, municipal engineering, environmental engineering, etc.

Keys for installing the Gratings

The cross bars should be on the top while installing the gratings. The 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

Welding Fixed

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

Use of Clips and Screws

3.Space for cutouts 
When the cut of a corner is necessary while meeting a round obstacle, the diameter of the corner should be at least 50mm wider than that of the round obstacle. All rectangular cutouts are made with a space no wider than that of the flat iron of the graings.
