Riveted Steel Grating

Riveted grating is one of the steel grating products available with high load capacity, flexibility, alkali and acid resistance and anti-slip surface.

It uses high-strength rivets to fuse the reticulated and bearing bars together and forms a solid joint.

It can be constructed of carbon steel, stainless steel or aluminum.

Additionally, it is available in both smooth and serrated surfaces. Riveted grating can be widely used as stair treads, walkways, floors, covers and bridge decking.

How to Make Riveted Steel Grating?

First, arrange the cut flat steel and cross bars according to the spacing required by the design, then use a rivet gun or other riveting equipment to pass the rivets through the connecting holes of the flat steel and the crossbar, and deform the rivets by squeezing or hammering, so that the flat steel and the crossbar are firmly connected together.

Riveted gratings are available in carbon steel, 6000 series aluminum, and 300 series stainless steel. These products are manufactured with bearing bars spaced 1-1/8” or 3/4” apart, with standard rivet spacing of 7” on center. Optional close rivet spacing of 3-1/2” on center is also available.

Standard serrations consist of the teeth of the grating bar being raised slightly above the top plane of the bearing bar during assembly. Alternatively, the user may specify 100% serrations, where both the bearing bar and cross member are provided with serrations.
