Materials of Construction Site Container Houses

The main materials of construction site container houses include steel structural frames and enclosure panels, with color-coated steel sheets or sandwich panels being the primary choices for the enclosure panels. Specifically:

1. Steel Structural Frames
   The steel structural frame is the core load-bearing structure of container houses. It is typically formed by welding or bolting galvanized steel pipes or section steels. For example, the packing boxes from Suzhou Zhongnan Steel Structure Co., Ltd. feature a full steel structural frame with galvanized steel structures of a thickness of ≥2.0mm, capable of withstanding wind speeds up to Level 10 and meeting national earthquake resistance standards. This structure is characterized by high strength and corrosion resistance, enabling it to bear significant loads and wind pressures, ensuring the stability of the house under extreme working conditions.

2. Enclosure Panels
   Enclosure panels mainly include exterior wall panels and roof panels, with commonly used materials being color-coated steel sheets and sandwich panels.

• Color-Coated Steel Sheets: These are made from galvanized steel sheets or cold-rolled steel sheets as the base material, with a colored coating applied on the surface, offering corrosion resistance and aesthetic appeal. For example, the panels of color-coated steel houses at construction sites in Baotou are made of galvanized steel sheets with a thickness ranging from 0.3 to 0.6mm, filled with polystyrene or rock wool inside to form a sandwich structure, which is both lightweight and strong.
• Sandwich Panels: These consist of two layers of metal panels with a core material in between, typically polystyrene, rock wool, or glass wool, providing excellent thermal insulation, sound insulation, and heat preservation properties. For example, container houses in Jining use 100mm rock wool sandwich panels, which can meet basic insulation requirements in environments as cold as -30 degrees Celsius.

3. Other Auxiliary Materials
   In addition to the main structure, container houses may also use other auxiliary materials such as fireproof materials, sealing strips, and connectors. For example, materials with a fire rating of B1 or above can effectively delay the spread of fire; ethylene propylene diene monomer rubber sealing strips can improve the airtightness and weather resistance of the house.
