Advantage Category |
Specific Description |
Thermal Insulation |
Core materials (such as rock wool, polystyrene, etc.) have low thermal conductivity, which can effectively block heat transfer and meet the temperature control needs of different climatic regions. |
Fire Resistance |
Some core materials (such as rock wool, glass wool) are non-combustible. Combined with the fire-resistant coating of color steel plates, they can delay the spread of fire and improve the fire safety level of buildings. |
Structural Strength and Durability |
The outer color steel plates have high strength, and the sandwich structure has good toughness, which can bear a certain load and impact, is not easy to deform, and has a service life of more than 10-20 years. |
Construction Convenience |
Lightweight (about 10-30kg/m²), with low requirements on the load-bearing capacity of building foundations; factory-produced standardized products, on-site splicing and installation, significantly shortening the construction period. |
Aesthetics and Maintainability |
The surface has various color coatings, with a neat appearance that does not require additional decoration; the coating is acid and alkali resistant, corrosion resistant, and UV resistant, and daily maintenance only requires regular cleaning with low cost. |
Sound Absorption and Noise Reduction |
Porous core materials such as glass wool can absorb sound waves, reduce noise transmission, and improve the internal acoustic environment of buildings (such as schools, hospitals, etc.). |
Wide Applicability |
Core materials and thickness can be flexibly selected according to needs, meeting the functional requirements of various building scenarios such as industrial workshops, residences, cold storage, and prefabricated houses. |
