Container House Assembly Materials
Container house assembly materials mainly include steel, thermal insulation materials, panels, doors and windows, and other auxiliary materials.
Steel: Steel is the primary structural support material for container houses, including angle steel, channel steel, and tubular steel. High-strength weather-resistant steel (such as Q355B grade) is commonly used for the main frame of the container body. Its yield strength is approximately 30% higher than that of ordinary carbon steel, enabling the formation of a self-balancing system through rigid connections between corner fittings and side beams, reducing the need for additional reinforcement components. Steel must possess good corrosion resistance, typically achieved through hot-dip galvanizing or the application of anti-corrosion coatings (such as a combination of epoxy zinc-rich primer and polyurethane topcoat) to extend its service life.
Thermal Insulation Materials: To cope with extreme temperature environments, container houses require the filling of thermal insulation materials to maintain internal comfort. Rock wool, glass wool, polyurethane foam, or EPS (expanded polystyrene) are common choices. For example, rock wool layers are controlled to a thickness between 75 mm and 100 mm, with a thermal conductivity below 0.040 W/(m·K). When combined with a 5 mm air layer to form a composite structure, the overall heat transfer coefficient (U-value) is below 0.5 W/(m²·K), effectively reducing condensation risks and extending the lifespan of the steel structure.
Panels: The interior and exterior decoration of container houses rely on various types of panels. Exterior wall panels commonly use color-coated steel sheets, calcium silicate boards, or cement fiber boards, offering both durability and fire resistance. Interior walls and ceilings often employ lightweight materials such as calcium silicate boards or wood to enhance living comfort. Floors utilize cement fiber boards or steel-wood composite flooring to meet load-bearing and wear-resistant requirements.
Doors and Windows: The door and window systems must balance ventilation and sealing performance, typically using aluminum alloy materials (such as sliding windows and bathroom doors), paired with high weather-resistant polyester resin coatings or moisture-proof aluminum foil layers to adapt to temperature variations and prevent condensation. Some designs also incorporate skylights or ventilation openings to optimize air circulation.
Other Auxiliary Materials: These include waterproofing systems, sound insulation materials, flooring, and suspended ceilings, selected based on specific needs. For example, waterproofing systems may employ asphalt felt or polymer waterproof coatings; sound insulation materials use acoustic cotton or rubber sealing strips; flooring options include PVC flooring or composite wood flooring to enhance aesthetics and practicality.
