The column formwork allows speedy assembly and assembly on site while reducing labor and crane time. The forms, made of steel or aluminum sometimes with a wooden form-face liner, can be accustomed on site to give diverse column sizes. Metal formwork systems can have primary concreting platforms with guard rails and access equipment comprising ladders. This diminishes the need for autonomous access. In some systems the props used to stabilize the column formwork are essential. The metal forms are easy to clean and reprocess with little surplus generated compared with old-style formwork.
