Can you recommend some materials for foldable housing to me？

framework materials
Hot dip galvanized steel: Q235 steel with a wall thickness of 2.0mm, galvanized layer ≥ 80 μ m, strong corrosion resistance, and a service life of over 20 years.
Aluminum alloy: Lightweight design, suitable for manual folding structure, but slightly less load-bearing than steel.
Wall panel material
Rock wool sandwich panel: A1 level fireproof, density ≥ 120kg/m ³, moisture-proof and waterproof, strong compressive strength.
Orange peel patterned color steel composite board: surface waterproof, customizable color, filled with EPS or rock wool.
Connecting materials
Stainless steel axis: wear-resistant, supports opening and closing more than 100000 times, rust proof.
Hot dip galvanized hinges: full welding process, reserved drainage outlet, and rainwater retention.
Other materials
Floor/ceiling: A-grade fireproof glass magnesium board, fire resistance limit ≥ 5 hours, non-toxic release.
Doors and windows: Steel safety doors+PVC sliding windows, balancing safety and ventilation.
