The material we used to make our grating products is of standard or higher quality ,like Q235,A36 ,16Mn,steel,AISI 304 ,316 stainless steel,not only material grade can match the international grade but also the production technology and quality control system upto the international standard ,there is no barrier can stop us for supply our grating products to any corner of the world,we not only supply gratings products but also offer our solutions for your project ,since we have rich experience with it , we are good at gratings .
The bar grating also can be divided by different shape of bearing bars , plain ,serrated and I-shape ,of which plain steel bar grating is the most widely used type ,70% projects used this type,because it is made by auto-welding machine,low production cost,good quality and quick delivery,serrated type is very similar to the plain type, same process of production,only difference is made the bearing bar serrated before welding,but it increased the surface friction. The reason for less I-shape graing is because this type normally used for special project,not big ones, the material is aluminium alloy.
Common specs for steel bar grating .bearing bar thickness 3mm, 4mm, 5mm, 6mm,at pitch 20mm, 25mm, 30mm, 32mm,40mm,and cross bar pitch 50mm,75mm,100mm ,our common stock size is 1meter wide , 6meter length, for export choice ,5.8meter lengt to fit 20gp container .it normally packed in 5pcs or 10pcs bundles for container loading.
Press locked steel grating is a another very important type,different from bar grating ,there is no twisted cross bars,It is formed by using tremendous hydraulic pressure to bond the two close-tolerance slotted bars together, permanently locking the cross bars into the notched bearing bars,Press Locked Grating is specified due to its clean, smooth look as well as supporting the same loads as welded bar grating ,but we do not recommended for rolling loads ,since it is not the economic option for big project ,however you can sometimes see it at commerical center,subway,shopping mall with good looking .
