What Materials Are Used for Container Houses
Common materials for container houses include steel, aluminum alloy, fiberglass-reinforced plastic, and color-coated steel plates, among others.
Steel: It is the most commonly used material for container houses, especially low-alloy high-strength structural steel and ordinary carbon steel. Steel container houses offer high strength, a sturdy structure, good weldability, excellent water tightness, and are cost-effective. However, they are relatively heavy and have poorer corrosion resistance. Some container houses use galvanized steel, which has high corrosion resistance and a service life of over 20 years.
Aluminum Alloy: Aluminum alloy container houses are lightweight, aesthetically pleasing, highly corrosion-resistant, flexible, easy to process, and have a long service life. Their drawbacks include higher costs and poorer weldability. Nevertheless, their overall performance meets high-end demands and is suitable for scenarios requiring lightweight and high corrosion resistance.
Fiberglass-Reinforced Plastic: Fiberglass-reinforced plastic container houses offer high strength, good rigidity, a large internal volume, and advantages such as heat insulation, corrosion resistance, and chemical resistance. They are easy to clean and repair. Their drawbacks include relatively heavy weight, susceptibility to aging, and reduced strength at bolt-tightening points. They are suitable for environments requiring high heat insulation and corrosion resistance.
Color-Coated Steel Plate: Color-coated steel plate container houses use color-coated steel plates as the exterior wall material, filled with insulation materials inside, combining aesthetics and practicality. Their advantages include low cost, short construction periods, and customizable exterior designs and internal layouts. They are widely used in temporary or semi-permanent scenarios such as construction site dormitories and wild campsites.
In addition, some container houses also use corrugated plates, rock wool, polyurethane, and other composite materials as interlayer fillings to enhance insulation, fire resistance, and sound insulation. For example, the residential container houses in Ma'anshan City are welded with light steel frames, with exterior walls covered with hot-dip galvanized steel plates or color-coated plates, and interlayers filled with rock wool or polyurethane, ensuring structural stability while improving fire resistance and insulation.
