Container Integrated House Color Steel
The application of color steel in container integrated houses mainly involves aspects such as material selection, structural design, functional integration, and multi-scenario adaptation. Its core is to achieve structural stability, rapid deployment, and environmental sustainability through the combination of high-strength color steel frames and composite panels.
1. Color Steel Material Selection and Structural Optimization
Color steel is mainly used as frame and enclosure structural materials in container integrated houses. Taking Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. as an example, it uses high-strength weathering steel (such as Q355B grade) as the main frame of the container body. The yield strength is increased by about 30% compared to ordinary carbon steel, enabling a single container body with a length-to-width ratio close to 2:1 to form a self-balancing system through rigid connections between corner fittings and side beams. The longitudinal corrugated plates on the top of the container body are made of color steel. Their corrugated geometric shapes can disperse roof loads, avoid local buckling, and reduce material usage by about 15%. In addition, after shot blasting and rust removal, the surface of the container body is sprayed with zinc-rich primer and polyurethane topcoat to form a protective system, enabling the steel to maintain an effective service life of more than 15 years in the northwest wind-sand and temperature-difference environment.
2. Thermal Performance Compensation of Color Steel Composite Panels
To address the issue of high thermal conductivity of metal container bodies, color steel composite panels improve thermal performance through a multi-layer structure. For example, companies producing residential container houses in Hohhot generally adopt a three-layer structure: the outer layer is a 0.6-millimeter-thick galvanized color steel plate to resist wind-sand erosion, the middle layer is filled with 80 to 100 millimeters of rock wool as the main insulation layer, and the inner layer uses PVC-coated steel plates to reduce thermal radiation. Some enterprises also add an elevated layer at the bottom of the container body to block the conduction of ground cold bridges, reducing indoor temperature fluctuations by about 40% compared to traditional color steel plate houses.
3. Functional Integration of Color Steel in Modular Integrated Houses
Color steel also plays a functional integration role in container integrated houses. For example, Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. integrates pre-buried pipelines within the chassis of the container body and adopts quick-connector designs to reduce on-site slotting and installation errors. Shandong Zhongyu Steel Structure Engineering Co., Ltd.'s packing-box units achieve full prefabrication of walls, roofs, and floors through the combination of color steel frames and rock wool sandwich panels, reducing on-site installation errors from the centimeter level to the millimeter level.
