Self-assembly Materials for Container Houses
Self-assembly materials for container houses mainly include four categories: core framework materials, wall panel materials, lining and flooring materials, and auxiliary materials.
Core framework materials serve as the supporting structure of container houses. Weathering steel is a common choice, which forms a dense oxide layer on its surface by adding alloy elements such as phosphorus, copper, chromium, and nickel, effectively resisting corrosion in high-humidity and high-salinity environments along rivers and coasts. Hot-dip galvanized square tubes form a composite structure with a compressive strength of 150-160kg/m³ through the metallurgical bonding of zinc alloy coatings and steel, capable of withstanding stacking loads of container houses and impacts from extreme weather conditions, with a service life exceeding 20 years, suitable for highly corrosive scenarios such as deserts and coastal areas.
Wall panel materials directly affect the thermal insulation, fire resistance, and appearance performance of the house. Orange peel pattern color-coated steel composite panels are the mainstream choice, with their surfaces featuring fine concave-convex structures formed through special embossing processes, dispersing the flow path of rainwater to prevent water accumulation and rusting. The double-sided orange peel pattern design enhances the rigidity of the panels through physical morphology while supporting customization in various colors such as white, wood grain, and gray. The internal filling materials of the wall panels include EPS (expanded polystyrene foam), PU (polyurethane foam), and Class A fire-resistant rock wool, with rock wool not softening or deforming at 800℃, releasing no toxic smoke during fires, and significantly enhancing the compressive strength of the wall panels.
Lining and flooring materials need to balance functionality and durability. High-strength bamboo-wood composite floors typically have a thickness of over 28 millimeters, combining the elasticity of wood with the compressive strength of bamboo, capable of withstanding the碾压 (crushing, here it means the heavy pressure) of forklifts weighing several tons. The interior wall cladding of container bodies often uses anti-corrosion and fire-resistant plywood or magnesium oxide boards, with the latter using magnesium oxide cement and glass fibers as the main raw materials, achieving a Class A1 non-combustible standard in terms of combustion performance, with a fire resistance limit of ≥5 hours, smoke toxicity of AQ1 level (non-toxic release), and a 15mm thick standard board capable of bearing 8 tons/m², supporting 3-layer stacking, and exhibiting excellent waterproof and moisture-proof performance, with an water absorption rate of ≤3% after 48 hours of immersion, suitable for plum rain weather in southern regions.
Auxiliary materials cover细分领域 (sub-fields, here translated as 'sub-sectors') such as thermal insulation, sealing, coatings, and accessories. Rock wool and polyurethane foam are commonly used fillers in sandwich panels, focusing on fire resistance and thermal insulation performance, respectively; ethylene propylene diene monomer rubber sealing strips can withstand temperature variations of tens of degrees, preventing cracking and aging at container body joints; high weather-resistant polyester powder coatings significantly enhance the adhesion and UV resistance of exterior wall coatings through high-temperature curing processes; hot-dip galvanized fully welded hinges use stainless steel axles, capable of withstanding over 100,000 times of opening and closing friction, avoiding rusting and jamming, with external hinges on folding containers also featuring reserved water outlets to prevent rainwater accumulation.
