Q:How is steel formwork constructed?

Steel formwork is constructed by following a systematic process that involves several steps. The first step is to determine the dimensions and requirements of the concrete structure that needs to be formed. This includes taking into account the shape, size, and design of the structure. Once the dimensions are finalized, steel sheets are cut according to the required sizes and shapes. These sheets are then assembled and connected using different methods such as welding or bolting, depending on the design and strength requirements. The connections between the steel sheets are essential to ensure stability and rigidity of the formwork. After the assembly of the steel sheets, additional components such as stiffeners, braces, and beams are added to provide structural support and reinforcement to the formwork.
