Materials for Container Houses

The main materials used in container houses include steel structural frames, enclosure panels, thermal insulation materials, door and window materials, and auxiliary accessories, as detailed below:

Steel Structural Frames

The steel structural frame is the core supporting structure of container houses, typically made from channel steel, angle steel, and tubular steel. The thickness of the steel used for main beams and columns directly affects the load-bearing capacity and safety of the house. For example, columns used in multi-story combined containers often employ 6mm thick square steel, with reinforcing ribs added at connection nodes to enhance overall compressive strength. Additionally, the frame undergoes galvanizing or anti-corrosion spray treatment to improve corrosion resistance and extend service life.

Enclosure Panels

Enclosure panels are used for the walls and roofs of container houses, with common materials including color-coated steel plates, rock wool panels, glass wool sandwich panels, and polyurethane foam panels. Among these, rock wool panels are widely used in scenarios requiring high safety standards due to their Class A fire resistance, moisture and corrosion resistance, and sound and thermal insulation properties. Polyurethane foam panels, on the other hand, are an economical choice due to their good thermal insulation performance and low cost. The thickness and material of the panels are determined based on the usage environment, with thicker insulation layers required in cold regions to meet thermal insulation needs.

Thermal Insulation Materials

To enhance the comfort of container houses, thermal insulation materials such as rock wool, glass wool, polyurethane foam, and EPS (expanded polystyrene) are filled between the steel structure and enclosure panels. These materials effectively reduce heat transfer, prevent steel structures from deforming under extreme temperatures, and lower energy consumption.

Door and Window Materials

Doors and windows are important components of container houses, typically made from aluminum alloy, which offers advantages such as lightweight, aesthetic appeal, corrosion resistance, and thermal insulation. Door and window types include sliding windows, casement windows, and skylights, with some high-end products equipped with double-glazed units to enhance sound and thermal insulation performance.

Auxiliary Accessories

In addition to the main materials, container houses also require auxiliary accessories such as screws, rivets, seals, drainage systems, and electrical conduits. For example, EPDM rubber seals are widely used for door and window sealing due to their strong weather resistance, while pre-embedded conduits simplify on-site installation and improve construction efficiency.
