The core material system of a container home must balance structural strength, anti-corrosion performance, and indoor comfort. Here is some industry-specific information regarding key material components:
Structural Steel
The main body of the container is typically constructed from weathering steel (Corten steel), a material that possesses inherent corrosion resistance. The vertical columns supporting the expandable sections use 150×150 galvanized steel tubing; galvanizing is the primary method for preventing steel rust. Industry standards require a galvanizing coating weight of at least 80g/m², though hot-dip galvanizing can achieve over 500g/m², offering superior adhesion and corrosion resistance. Steel grades such as Q235 or Q345 are typically selected to ensure adequate load-bearing capacity.
Flooring Material-Stone Plastic Composite (SPC)
SPC flooring is the mainstream choice for container home interiors. This material is lightweight (≤2kg/m²) and formaldehyde-free, while offering waterproof, fire-resistant, and wear-resistant properties; it can be installed directly onto the steel floor plate without the need for additional leveling. For container homes requiring lightweight finishes, SPC flooring offers distinct advantages in terms of weight reduction and environmental friendliness.
Interior Walls and Ceilings-Integrated Wall Panels
Integrated wall panels typically utilize a structure combining light-gauge steel framing with bamboo-wood fiber boards (thickness ≤2cm). This solution ensures a smooth, aesthetically pleasing wall surface while providing thermal insulation and soundproofing-a common approach to balancing weight and comfort in container home interiors.
