Bar Grating--Construction Equipment & Tools

Product Description

Bar 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 weldingring which is controlled by computer, So we can produce high quality gratings with firm welding, smooth surface and high strength.
Classification: Raised (Standard, Regular)and Flattened

Surface Process of Gratings
1. Normally, Hot 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 then 5mm, the weight of average Zinc Layer will not be less than 460G/M2. The quailty and requirements after hot galvanizing are subject to the standards of GB/T 13912.
2. To gain protection layer through the ways of spraying, brushing and soaking.

Steel Gratings Most_Poular Specifications
1. The grating that the pitch between bearing bars is 30mm, is most widely used type in industrial field. Among normal types, it has the strongest resistance to surface lash.
2. The grating that the pitch between bearing bar is 40mm is the most economical and lightest type. It is the best choice for you on occasions that the clear span is small.
3. The grating that the pitch between bearing bar is 60mm and the pitch between cross bars is 50mm is developed specially for mining industry, it solves the problem of mineral splash on the plate. So it is often appointed to use in processing works, of mining industry.
4. The grating with the pitch of 30mm between bearing bars and of 76mm between corss bars is the most popular type used hone and abroad, it is proper for many applications such as walkways, platforms, etc.
