How to choose materials for foldable housing?

The material selection for foldable housing should take into account lightweight, durability, and functionality. The following are the key solutions:
1. Framework material
Aluminum alloy: Recommended aviation grade 6061-T6 aluminum alloy, which is 1/3 lighter than steel structures, has strong impact resistance, and is suitable for push-pull folding structures.
Hot dip galvanized steel: used for folding box room frames, with a compressive strength of 150-160kg/m ³, corrosion resistance, and a lifespan of over 20 years.
2. Wall panels and enclosure materials
Color steel composite panel: The outer layer is orange peel patterned color steel, and the inner layer is filled with A-level fireproof rock wool (800 ℃ non combustible), which is waterproof and moisture-proof.
Polycarbonate board (PC board): with a density half that of glass, it has excellent sound insulation performance and is suitable for sunroom ceilings.
Glass magnesium board: Class A fireproof, with a load-bearing capacity of 8 tons/m ², waterproof and moisture-proof, suitable for floors and ceilings.
3. Connection and auxiliary materials
Hinge and axis: using hot-dip galvanized hinges and stainless steel axis, supporting more than 100000 opening and closing cycles, rust proof.
Sealing strip: Made of EPDM material, high temperature resistance and good sealing performance, enhancing thermal insulation performance.
4. Environmental protection and cost considerations
Recyclable materials, such as steel and aluminum, reduce resource consumption.
Comprehensive cost: Folding design can reduce transportation costs by 80%, but it is necessary to avoid low-priced and low-quality products.
