Zoje Heilongjiang provides high-quality steel structures. In response to your question, I have extracted some industry papers from our website to answer you. You can also search the answers yourself.

(1) The industrialization degree of fittings is low. Harbin steel structure residence is a complex integration of technology, components and materials, and it is the discovery direction and inevitable product of the gradual modernization of housing industry. Therefore, steel structure housing should be industrialized first. However, at present, the parts related to the technically mature steel structure residence are either lacking or have a low degree of industrialization, or lack technical standards or are inconsistent with the relevant standards of the steel structure residence, especially the walls, floors, balconies, stairs, etc. And there is a lot of wet work, which leads to the embarrassing situation of "wearing a T-shirt and tie" in steel structure residential buildings.

(2) The lack of modularity seriously restricts the industrialization development of steel structure residence in Harbin. At present, only stairs, doors and windows, kitchens and bathrooms have modular standards, but most parts such as roofs, partitions and elevators still lack unified modular standards.

(3) Harbin steel structure design optimization, such as building plane and column network optimization, cold-formed rectangular tube instead of welded box column, variable cross-section column application, buckling-restrained brace application, etc. It can reduce the project cost and improve the economy of Harbin steel structure residence.

(4) The lack of design specifications leads to some problems such as the failure to promote some new high-quality steel products or the poor use of superior materials.

(5) anticorrosion.

(6) Application of high strength steel.

(7) The detail processing technology needs to be improved.

(8) The quality of the construction team needs to be improved.

(9) Lack of national policy support measures
