Swage Locked Grating with Rectangular, T, or I Bar Types

There are two galvanized swage locked gratings of different sizes placed together on the ground.

Swage locked grating with rectangular, T, and I bar types meet your different demands.

Swage locked grating is also called aluminum grating, because it's mainly made of aluminum steel bars. Other materials can be stainless steel bars. 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. There are three kinds of bearing bars: rectangular bars, T bars or I bars. I bar swage-locked grating is lighter and cheaper than the rectangular bars swage-locked grating, and is the most widely used type. And now the close mesh steel grating is also available of 7/16" to 11/16" bearing bar spacing for special uses.
