Light Steel Container House Production
The production of light steel container houses involves multiple aspects such as structural design, material selection, production processes, and scenario adaptation. The core lies in achieving efficient construction and recycling through modular and standardized design.
I. Structural Design: Using Light Steel Keels as the Core Load-Bearing System
Light steel container houses adopt hot-dipped aluminum-zinc light steel keels or hot-dipped galvanized square steel frames as the main structure. By optimizing mechanical design, they ensure load-bearing capacity. For example, the Hebei Chinese-style courtyard product uses hot-dipped aluminum-zinc light steel keels, paired with rock wool sound insulation and thermal insulation layers and OSB structural panels, forming a lightweight and high-strength structural system. Baotou Xinxing Color Plate Steel Structure solves the problem of insufficient floor stiffness by adding C-shaped steel purlins between the container bottom beams, allowing the boxes to be stacked three layers high while remaining stable. The structural stability must comply with the GB50011-2010 seismic code. Products from leading manufacturers can withstand wind speeds of up to 12 levels and seismic intensities of up to 8 levels.
II. Material Selection: Balancing Performance and Environmental Protection
Wall materials use Class A fire-resistant and thermal insulation layers such as rock wool and polyurethane, covered with antique metal tiles, clay blue tiles, or thickened rock wool color steel plates, achieving an integrated solution for fire prevention, thermal insulation, and sound insulation. For example, Yashun Light Steel produced double-wing expandable boxes for a project in Chile. By using a broken-bridge lining structure (filling hard polyurethane foam between the steel frame and interior wall panels), it reduces heat conduction efficiency, resulting in a 40% decrease in indoor-outdoor heat exchange efficiency. The surface treatment of steel involves shot blasting for rust removal, followed by spraying with zinc-rich primer and polyurethane topcoat. The protective system can maintain the structure's effective lifespan for over 15 years in the windy and sandy environment of northwest China.
III. Production Process: Combining Modularization and Intelligence
The production process covers automated keel processing, modular assembly, and weld-free quick installation. For example, a smart factory in Guangdong achieves collaborative operations among welding, assembly, and grinding robots through a 400-meter fully automated production line, producing 50 steel structural modules per day with manufacturing precision controlled within 1-2 millimeters. Suzhou Zhongnan Steel Structure adopts bolt assembly technology, with a single module installation taking only 4 hours, improving efficiency by 50% compared to traditional welding processes. Products from leading manufacturers can be disassembled and reused an average of more than 8 times, reducing construction waste emissions by 90% compared to traditional fixed temporary buildings.
IV. Scenario Adaptation: From Engineering Camps to Cultural and Tourism B&Bs
Customized functional modules meet diverse needs: engineering camp scenarios focus on wind and earthquake resistance and quick installation, commercial spaces emphasize spatial flexibility and reusability, and cultural and tourism projects focus on外观 (appearance) personalization and cultural adaptation. For example, the 20-foot double-wing expandable box designed by Yashun Light Steel for a project in Chile collapses the side spaces during transportation to improve loading efficiency. When expanded, it forms a 36㎡ usable area that can be flexibly switched between a residence (two bedrooms, one living room, one kitchen, and one bathroom) or a storage space. Modular design results in a higher room utilization rate than traditional brick-and-mortar houses, with applicable scenarios covering rural self-built houses, vacation B&Bs, and emergency support.
