Knock Down SS Spiral Staircase

Round stairs are called either circular stairs or spiral stairs depending on the stair design. Circular stairs follow a circle with a single center of curvature and a large radius.The main characteristics of spiral staircases or a round staircase are their central columns and a compact, circular staircase design, which means relatively little surface area is required for installation. You can also use the word as a verb when something moves in a spiral shape: "Then the wind died and I watched my kite spiral down to the ground." The origin of spiral is the Medieval Latin spiralis, which means "winding or coiling," from a Greek root: speira, "coil, twist, or wreath."
