Container House Decoration Standards
The decoration standards for container houses should be controlled from three aspects: material acceptance, factory production quality, and on-site installation quality, while also meeting structural safety, functional suitability, and environmental protection requirements. The specific standards are as follows:
I. Material Quality Acceptance Standards The materials used in container houses must comply with national and industry standards. Steel should possess anti-corrosion and high-strength properties, typically achieved through galvanization or anti-corrosion treatment. Wall materials commonly use rock wool sandwich panels, which must meet the fire resistance rating of Class A and possess sound insulation and thermal insulation properties. Door and window materials should have anti-theft and waterproof functions, such as plastic-steel windows equipped with anti-theft grilles. Electrical materials (such as wires and sockets) must pass 3C certification, and air conditioning-specific sockets should be independently wired. All materials must provide inspection reports to ensure no excessive harmful substances.
II. Factory Production Quality Standards The factory production process should establish a quality traceability system, with key processes requiring on-site supervision. Welding of container structural units (corner posts, side beams, and skins) must be firm, without cold welds or cracks. Walls and frames should be connected using bolts with uniform spacing. Internal decoration should pre-install lighting, sockets, exhaust fans, and other equipment, with wiring hidden within wall cavities. Fireproof layers should completely cover the steel structure, with thickness meeting design requirements. Finished products should undergo waterproof testing to ensure no leakage.
III. On-Site Installation Quality Standards On-site installation should refer to BIM models or design drawings to ensure dimensional accuracy. Foundation construction should be level and solid, with container connections to the foundation using bolts or welding to prevent displacement. When connecting multiple containers, seals should be applied at joints to prevent rainwater infiltration. Interior decoration should complete flooring (such as anti-slip tiles), wall decoration (such as eco-friendly paint or wood veneer), and ceiling installation. Functional zoning should be reasonable, such as waterproofing and septic tank system installation in bathrooms, and reserved gas pipeline interfaces in kitchens. After installation, an overall inspection should be conducted, including structural stability, electrical safety, and ventilation effectiveness.
IV. Environmental Protection and Safety Requirements Decoration materials should comply with environmental protection standards, with formaldehyde emission levels below national standards. Containers should possess wind resistance (such as Class 8) and earthquake resistance (such as Class 6) ratings, with structural calculation reports provided. Fire resistance should pass fire safety inspections, with clear markings for escape routes. For long-term residence, additional insulation layers (such as polyurethane foam) and solar systems should be installed to enhance energy efficiency.
