According to the purpose of steel formwork, it can be divided into: civil building (house building) steel formwork and bridge steel formwork.

According to the pouring shape of steel formwork, it can be divided into box girder formwork, T-beam formwork, capping beam formwork, hollow beam formwork, circular formwork, beam protection formwork and pier head formwork.

There are also combined steel formwork, which can be divided into large formwork, small formwork, middle formwork, internal angle and external angle.

Steel formwork: consists of plate structure, support system, operating platform and accessories. It is a tool template for cast-in-place wall and wall structure construction. It is characterized by taking the width, depth and height of the building as the size of the large formwork.

Advantages of steel formwork: reinforcement system, high strength of members, high combined stiffness, high manufacturing accuracy of plates, tight joint, difficult deformation, good integrity of formwork and strong seismic capacity.

Disadvantages of steel formwork: the formwork is heavy, which needs to be hoisted and installed by lifting machinery, and the cost is high.
