In particular, the wall made by combining cold-formed special-shaped steel and gypsum board materials is particularly excellent in sound insulation. When we were singing on KTV, we could not hear the sound outside. The most important thing was the use of this material. Hollow slabs made of cold-formed special-shaped steel after certain processing have better sound insulation effects and have penetrated into many aspects of our lives. This material can also prevent the erosion of moisture, even if exposed to air, the appearance is not easily corroded by moisture.

The combination of cold-formed special-shaped steel and fiberglass wool can make a good thermal insulation material, its thermal insulation effect is much better than traditional brick walls, so it is widely used in many large refrigerated warehouses, which can be effective Avoid wall cold bridge problems caused by low temperature environment.
