الوصف

Swage-locked grating, also called aluminum grating, is mainly made of aluminum steel bars, and other materials can be stainless steel bars. The bearing bars can be rectangular bars or I bars. I bar swage-locked grating is the most widely used type. In the same depth, I bar swage-locked grating can supply the same strength with the rectangular bar swage-locked grating, but it is lighter and cheaper than the rectangular bars swage-locked grating.

The cross bars are inserted into pre-punched holes of bearing bars and then it is hydraulically swaged under tons of pressure to lock the bearing bars in place. In these processes, the swage-locked grating form a permanent locked structure.

The standard bearing bar spacing is **3/*6" or *5/*6". There a type of new products named as close mesh steel grating, which has the closer spacing than the standard. The spacing of close mesh steel grating can range from 7/*6" to *1/*6".
