Power Steel has developed a scaffolding drop head system easy to use and very functional. After 7 days of pouring concrete on a slab, we can dismantle all horizontal from work accessories : girders, beams, panels without removing the vertical supporting frame. This is very advantageous and economic in formwork. The system is designed to support floors of different thickness up to 1 m concrete height. Briefly, it is very useful for residential and commercial buildings and for bridges.
