A structural form that forms an enclosure system on the outside to play the role of heat preservation, waterproofing, and sound insulation. Common steel structure enclosure structures include metal plates, glass curtain walls, stone curtain walls, and plate curtain walls. Steel materials such as aluminum-magnesium-manganese plates and color steel plates have high strength, good wind and earthquake resistance, and corrosion resistance, which makes steel structure enclosure structures perform well in special occasions such as large-span buildings, venues, and bridges.

1. Resist natural disasters: The enclosure structure can protect the building from natural disasters such as strong winds and earthquakes, and improve the stability and durability of the building.
2. Fire resistance: The enclosure material has high fire resistance and can effectively reduce the damage to the building caused by fire.
3. Anti-theft function: The enclosure structure can effectively prevent outsiders from entering the building and protect the safety of property and personnel.

The enclosure structure materials usually have good thermal insulation properties, which can effectively reduce the temperature changes inside the building and improve the comfort of the building.

1. Recyclable materials: The materials of the enclosure structure are usually recyclable and renewable, reducing the generation of construction waste.
2. Energy saving and environmental protection: The enclosure structure materials can effectively reduce the energy consumption of the building and reduce pollution to the environment.

The construction efficiency of the steel structure enclosure structure is high, which can shorten the construction period. For example, the construction efficiency of the steel structure is 4 times that of traditional buildings, and the construction period is only one-third of that of traditional buildings.
