One .Various kinds of large assembled steel formworks, including cylinder, elliptic cylinder, cone, square pillar, rectangle pillar, hollow pier, inner and outer formworks for railway hydraulic tank girder and Model T girder formwork, can be widely applied to the construction of road bridge, railway bridge, tunnel, power station, and etc.

Two. With concise structure, reliable performance, convenient operation, standard welding, accurate molding and evenness acquired by automatic assembly line welding, it has overcome all kinds of assembling defects of the same formworks in this industry, and achieved standardized assembling of large plain formwork, inner and outer corner formwork and juncture connector. It also achieved the best price/performance ratio and met the optimized assembling line demands, meanwhile, solved the widely existing problems in formwork industry, such as multiple standards, large formwork area, low general utilization ratio and high cost.
