Container House Structural Standard

The container house structural standard mainly covers aspects such as size specifications, structural performance, materials and processes, and safety and compliance, as follows:

I. Size Specifications Container houses are based on standard container sizes as basic modules. Common specifications include:

• 20-foot standard container: The external dimensions are approximately 6055×2435×2591mm, the internal clear space is approximately 5898×2352×2390mm, and the load-bearing capacity is about 25 tons.
• 40-foot standard container: The external dimensions are approximately 12024×2435×2591mm, the internal clear space is approximately 12024×2352×2390mm, and the load-bearing capacity is about 45 tons.
• Non-standard customized containers: Sizes can be adjusted according to needs, such as 10-foot, 16-foot, and 24-foot containers, but they must meet modular combination and transportation requirements.

II. Structural Performance

1. Wind and earthquake resistance:
   • It must comply with building seismic design codes (such as GB50011-2010) and modular building technical standards (GB/T 38264-2019).
   • Under extreme conditions, high-quality container houses can achieve a wind resistance rating of 12-13 and an earthquake resistance rating of 7-8, with a frame deformation rate of less than 0.3% (the industry's qualified threshold).
2. Structural stability:
   • A fully steel structural frame is used, and the thickness of the main beams and columns must meet standards. The welding process should be full without cold welds.
   • The frame connection method affects long-term stability. A fully welded structure is superior to a half-welded and half-bolted connection structure.

III. Materials and Processes

1. Wall materials:
   • Color-steel sandwich panels are usually used, filled with rock wool boards or polystyrene boards, balancing lightweight and thermal insulation performance.
   • The insulation layer must meet fire resistance ratings (such as Class A non-combustible or Class B1 flame-retardant), with a smoke concentration rating of Q1 and low smoke emissions.
2. Floor and roof:
   • The floor uses cold-rolled welded steel profiles, combined with rock wool boards, galvanized steel sheets, and PVC floors, with a flammability rating of Class B1.
   • The roof must have waterproof performance, and the lap joint method (such as 360° seaming) and the thickness of the insulation layer (such as 100mm) must comply with regulations.

IV. Safety and Compliance

1. International certifications:
   • Overseas projects must have international certifications such as CE and ISO to ensure compliance with the safety standards of the target market.
2. Export compliance:
   • The brand must provide one-stop export services, covering the entire process of customs declaration, customs clearance, and logistics to avoid project delays.
3. Fire prevention and corrosion resistance:
   • The container body must undergo overall galvanization or anti-corrosion coating treatment to extend its service life.
   • The electrical system must comply with electrical safety regulations, and doors and windows must be equipped with seals and anti-theft locks.
