Problems solved by technology

However, in practical applications, the prefabrication rate is one-sidedly pursued in buildings, especially the load-bearing structure also adopts prefabrication technology, which leads to poor seismic and crack resistance performance and hinders the development prospects of the market
At the same time, with the cultural needs of modern buildings, traditional precast concrete wall panels still have the problem of single surface decoration effect or the need for secondary decoration construction. The popularization of precast concrete wall panels is affected. Prefabricated prefabricated wall panels with excellent performance to fill this gap
