Problems solved by technology

This method has a long construction period and high overall cost
At present, some enterprises have developed prefabricated wall panels that integrate decoration, heat preservation and enclosure, but the disadvantages are also obvious, or the low strength affects the safety of use; or the weight of itself increases the load of the frame structure, or the decorative effect is relatively simple, which cannot meet the requirements Decorative needs of diversified buildings
