1, the connection between the frame and metope can't realize the good weather resistance, the integrity of metope depends only on the sealant. For manufacture and installation of the error, the gaps between the steel structure and the panel is not uniform in width, may need a lot of sealant, so usually cause not beautiful appearance. Recently there is a steel structure exposed project, only provide sealing strip sales staff was completely satisfied with the appearance of this project.
2, when used on knee brace beam, the main frame of high material utilization. But when the knee brace and bolted end plate when exposed to outdoor, maybe looks not very beautiful.
3, in the main structure of high quality color spray paint or galvanized surface paint factory very hard. In corrosion conditions, there was a moderate quality paint brush main structure may not have a long life.
4, some architects forget prefabricated metal building main frame is composed of a relatively thin plates, between web and flange plate welding are usually only in the web side. In addition to the structural engineer heart caused concern for solution, the one-side weld with smooth corner was comparable to that of hot rolled steel at the same time also can't provide good resistance to atmospheric properties.
