Concrete steel formwork is a professional steel forming tool specially used for prefabricating or cast-in-place concrete structures. Made of Q235B steel plate through cutting, bending, welding and reinforcement, it is detachable and reusable, mainly used to shape concrete components such as walls, beams, columns, slabs and inspection wells in construction projects. It is widely applied in municipal infrastructure, high-rise buildings, bridges, tunnels, communities and factories, replacing traditional formwork materials to realize standardized, industrialized and efficient construction. With high strength, excellent load-bearing capacity, high forming precision, tight splicing (no slurry leakage), convenient demoulding and customizable specifications (size, shape can be customized according to drawings), it can be reused hundreds of times, greatly reducing construction labor costs and improving project quality and construction efficiency, and is an indispensable core tool for modern construction projects.
