Stairways, Inc. offers a couple of grating options for spiral staircase steps and landings. Standard bar grating is cut from a sheet of grated steel and banded to form a spiral stair step. These spiral stair steps work well in industrial applications when dirt, oil and grease can be on the floor. Bar grate spiral stair steps can also come with a serrated edge for even less slippage. Our second grating spiral staircase step is radial grating. This step is handmade forming a radial pattern out from the center, beautiful and contemporary, and perfect spiral stair step for beach sand or snow and ice.
