Step Iron designed by us is a U-shaped device or a ladder used to climb or descend stairs. This iron is widely employed in the municipal and construction industries. To provide strength, the iron is formed of steel bars. It is a vital tool for masonry and drainage system maintenance. Step Iron is our most popular concrete manhole product because this is easy to install in new and existing concrete structures. It is made of virgin polypropylene copolymer plastic with structural carbon steel reinforcement.
