Container House Material Details
The main materials of container houses include wall panels, frames, floors, ceilings, accessories, and auxiliary materials. The specific details are as follows:
Wall Panel Materials
Both the inner and outer sides of the wall panels often use orange-peel-patterned color-steel composite panels. The surface forms subtle concave-convex structures through a special embossing process, effectively dispersing the flow path of rainwater and preventing water accumulation and rusting. The double-sided orange-peel-patterned color-steel layers enhance the rigidity of the panels through their physical form, with Grade A fire-resistant rock wool (which does not soften or deform at 800℃ and releases no toxic fumes) filled in the middle. This provides fire resistance, non-toxicity, and pressure resistance, preventing deformation during transportation or stacking. Some manufacturers also use foam boards (EPS/PU) or glass wool as filling materials, but their fire resistance is weaker than that of rock wool.
Frame Materials
The overall frame is mainly composed of hot-dip galvanized square tubes. Through the metallurgical combination of a zinc alloy coating and steel, the compressive strength reaches 150-160kg/m³, capable of withstanding the load of three stacked layers and extreme weather impacts. The corrosion protection period is three times longer than that of cold-dip galvanizing, with a service life exceeding 20 years. The hinges of folding boxes are made using a hot-dip galvanized full-welding process, with the axle made of stainless steel, capable of withstanding over 100,000 opening and closing frictions and preventing rust and jamming. The base is usually welded from channel steel. For example, the base of a 3×6m container house has nine channel steel columns placed horizontally and welded to the channel steel on both sides to enhance load-bearing capacity.
Floor and Ceiling Materials
The floors and ceilings are standardly equipped with Grade A fire-resistant magnesium oxide boards, made from magnesium oxide cement and glass fibers. They have a fire resistance limit of ≥5 hours, a smoke toxicity level of AQ1 (non-toxic release), and a 15mm thick standard board can bear a pressure of 8 tons/m², supporting three stacked layers. They are also waterproof and moisture-proof (with an absorption rate of ≤3% after 48 hours of immersion). Some scenarios may use steel-wood composite floors or cement fiber boards.
Accessories and Auxiliary Materials
Doors and windows often use aluminum alloy materials, which are lightweight, corrosion-resistant, and provide thermal insulation. Glass is used in doors, windows, or observation windows to increase lighting and视野 (view). In addition, lightweight materials such as plastic pipes and plastic boards are used for pipelines or decoration. Sealing strips and waterproof coatings are used to improve the house's airtightness, and soundproof materials (such as rock wool and glass wool) are used to enhance sound insulation.
