rectangular column box

A Rectangular Column Box is a reusable formwork system used in construction to mold and cast rectangular reinforced concrete columns. It provides accurate shape, size, and surface finish to vertical concrete elements. These boxes are made from high-strength materials such as mild steel or plywood with steel frames, designed to withstand the pressure of freshly poured concrete while maintaining structural alignment.
