Eaves of Container House and Activity Board House
The eaves of container houses and activity board houses typically use metal materials such as color-coated steel sheets. Some designs may incorporate waterproof membranes or composite panels, with the specific choice depending on the usage scenario, cost budget, and functional requirements.
Core Choice of Eaves Material: Color-Coated Steel Sheets
Color-coated steel sheets are a common material for the eaves of container activity board houses, with advantages including lightweight, high strength, corrosion resistance, and easy installation. Made from galvanized steel sheets or aluminum alloy substrates coated with a colored layer, they form a dense oxide film on the surface, effectively resisting erosion from rainwater, ultraviolet rays, and salt spray, thereby extending the service life of the eaves. For example, ready-made color-coated steel sheet eaves with iron sheet fences are often used in temporary buildings. With a typical thickness of 0.3-0.6 millimeters, they can meet structural strength requirements while reducing overall weight for quick assembly. Additionally, the corrugated design of color-coated steel sheets enhances drainage efficiency, reducing the long-term corrosion risk to the eaves from accumulated water.
Auxiliary Materials: Waterproof Membranes and Composite Panels
To improve the waterproof performance of the eaves, some designs add a layer of waterproof membrane beneath the color-coated steel sheets, such as SBS modified asphalt membranes or polymer self-adhesive membranes. These materials have excellent elongation and weather resistance, filling small gaps at the joints of the color-coated steel sheets to form a dual waterproof barrier, especially suitable for rainy or humid regions. If further thermal insulation is required, the eaves may use rock wool composite panels or polystyrene foam boards as interlayer materials. These panels have low thermal conductivity, effectively blocking external heat transfer, reducing indoor temperature fluctuations, and providing some sound insulation function to enhance living comfort.
Design Considerations: Balancing Functionality and Economy
The choice of eaves material should comprehensively consider usage scenario, cost budget, and maintenance convenience. For example, temporary container houses may prioritize lower-cost color-coated steel sheets, reducing initial investment by simplifying the structure; while long-term activity board houses may add waterproof membranes or composite panels to extend service life and reduce later maintenance costs. Additionally, the slope design of the eaves is crucial. A reasonable slope (usually ≥5%) ensures rapid drainage of rainwater, preventing leakage or material aging caused by accumulated water.
