Abstract
This product is a pipe for use as a staircase. The lower part is designed to avoid concrete foundations, allowing the upper part to be attached. Commercially available steps can also be attached to the lower and upper parts. Alternatively, the lower part can be fitted with a staircase (Registered Staircase No. 1795279). The bottom of the lower section has a non-slip surface with three holes; the middle hole is for drainage. The other holes are used for securing with pins or bolts.
