It can be roughly divided into flat formwork, beam formwork, corner formwork, stair formwork, etc. Different shapes and sizes of aluminum formwork can be designed according to different project drawings. It owns one set of formwork, three sets of supporting replace three sets of formwork and supporting of plywood formwork.
