Radial Grate tread w/ nosing is available in steel, aluminum, or stainless steel and can be incorporated into all kit and fully assembled stair models. Like the standard radial grate tread, the 1" x 3/6" flat bar construction with ¼" x 2" frame make for a very ridged and effective step. Radial grate tread offers all the benefits of a traditional bar grate step, while keeping a very contemporary clean finish, and with the checker plate nosing offers tons of traction. Radial Grate tread w/ nosing is a great option for applications that don't want to sacrifice appearance for functionality.
