Materials of 12-Meter Container Houses
The materials of 12-meter container houses mainly include three categories: main structural materials, auxiliary and functional materials, and special materials for special-purpose containers. Details are as follows:
Main structural materials are the core supporting components of container houses. Weathering steel, typically with grades Corten A or Corten B, is commonly used. This type of steel has high strength, high toughness, and good welding performance, enabling it to withstand various stresses during transportation and long-term use. The side and roof panels of the container body usually employ weathering steel plates with a thickness of 1.5mm-2.0mm, ensuring structural stability while reducing the overall weight. The floor panel adopts thicker steel plates of 2.0mm-3.0mm to withstand greater pressure and wear, ensuring the durability of the container house.
Auxiliary and functional materials also play a crucial role in container houses. In terms of sealing materials, rubber seals are key, often using ethylene propylene diene monomer rubber (EPDM). This material has excellent weather resistance and sealing performance, effectively preventing the intrusion of wind and rain and protecting the internal environment. For accessory materials such as door lock mechanisms, door hinges, and corner fittings, galvanized steel is commonly used and treated with hot-dip galvanizing to enhance its corrosion resistance and service life. Flooring materials include bamboo-wood composite floors or plywood floors, which are made by bonding multiple layers of high-strength bamboo strips or hardwood under high temperature and pressure, making them both environmentally friendly and durable. For internal reinforcement materials, aluminum alloy is widely used in non-load-bearing but lightweight-supporting structures such as sidewall stiffeners and ceiling beams due to its lightweight, high strength, and corrosion resistance.
Special materials for special-purpose containers are customized according to specific requirements. For example, polyurethane foam (PU) is used for the insulation layer, which has excellent thermal insulation performance, effectively reducing energy loss and improving the energy efficiency of the container house. The inner lining panels may be made of stainless steel to meet the requirements of food-grade or containers with extremely high cleanliness standards. In addition, some lightweight special-purpose containers also use aluminum alloy corrugated panels as external reinforcement materials to further reduce weight and enhance structural strength.
