Container House Design
Container house design materials cover the main frame, wall panels, flooring and ceiling, thermal insulation, doors and windows, and other accessories, as follows:
Main frame materials: Galvanized cold-rolled steel or hot-dip galvanized square tubes are commonly used. Galvanized cold-rolled steel ensures structural rigidity and rust resistance; hot-dip galvanized square tubes form a composite structure with compressive strength of 150-160kg/m³ through metallurgical bonding of the zinc-alloy coating to the steel, effectively bearing stacked container loads (up to 3 stories) and extreme weather impact, and adapting to highly corrosive environments such as deserts and coastal areas. Standard square tubes use full-penetration welding at frame joints, improving the box body's longitudinal rigidity by more than 30%. Hot-dip galvanized square tubes extend the anti-corrosion period by 3 times compared with electro-galvanizing, with a service life of over 20 years, and the zinc layer is 100% recyclable.
Wall panel materials: Both inner and outer sides of wall panels typically use orange-peel embossed color-steel composite panels. The standard box color is white with a white frame, and multiple custom colors are also available. The orange-peel surface forms a fine concave-convex texture through a special embossing process, effectively dispersing rainwater flow paths and preventing standing water and corrosion. Double-sided orange-peel color-steel layers also enhance panel rigidity through physical form. Wall panels can be filled with EPS, PU, or Class A fire-resistant rock wool. Zeyu container house wall panels are filled with Class A fire-resistant rock wool, which does not soften or deform at 800°C, releases no toxic smoke in a fire, and—after machine compression and sealing—significantly improves the panels' compressive strength.
Flooring and ceiling materials: Zeyu container houses are standard-equipped across the full line with Class A fire-resistant glass magnesium boards, mainly made from magnesium oxide cement and glass fiber. Combustion performance reaches A1 non-combustible grade, with a fire resistance rating of ≥5 hours, smoke toxicity at AQ1 grade, and 1350°C heat resistance that can withstand flame jets while maintaining structural integrity. The 15mm-thick standard board meets Class A fire protection and 8 tons/m² load-bearing requirements, supports stacking containers up to 3 stories, and is waterproof and moisture-proof. Cement sanded boards, cement pressure boards, solid wood flooring, and other options are also available for selection as needed.
Thermal insulation materials: Common combinations include exterior insulation boards + waterproof membrane. Frequently used materials include high-density polystyrene boards (EPS/XPS) and high-density polyurethane foam, covered with synthetic panels, metal sheets, or fiber cement boards to improve durability and appearance. Metal cladding + waterproof layer is also an option. Wood/fiber cement and similar exterior cladding offer better aesthetics and touch, but fire resistance and moisture protection must be combined with base treatment.
Door and window materials: Prefer doors and windows with good thermal resistance and airtightness. Broken-bridge aluminum or UPVC frames paired with insulating glass (double or triple glazing) are the mainstream choice; weatherstrips must be high quality and installed tightly. For multi-opening windows, skylights, and similar areas, thermal bridge control should be considered at the design stage, using low-conductivity materials and shading devices when necessary.
Other accessory materials: For example, exterior hinges on foldable containers use a hot-dip galvanized full-weld process, with two water outlets reserved underneath to prevent rainwater accumulation—a design covered by an exclusive patent. Interior hinge shafts use stainless steel, withstanding more than $13,889 opening and closing friction cycles without rusting or sticking.
