Liaozhong Container House

Container houses in Liaozhong are characterized by modular design, high-strength structures, and adaptability to extreme climates, widely used in infrastructure, municipal, and temporary residential scenarios.

I. Structural Design and Material Characteristics

Container houses utilize standardized metal frames (such as Q235B galvanized square tubes) combined with lightweight enclosure panels, achieving modular assembly through bolt tightening and riveting. This design ensures damage-free transportation and rapid on-site reassembly. The cross-sectional dimensions of the base frame, top frame, and columns are optimized through mechanical simulation calculations, with high-frequency welding machines completing key node fusion, ensuring structural rigidity meets wind and snow resistance standards. For example, products from Shandong Juhe Green Building Integrated Housing Co., Ltd. significantly enhance durability in Liaoning's freeze-thaw cycles and high winds by thickening profiles, strengthening node welding, and improving sealing performance.

II. Manufacturing Process and Quality Control

The production process follows the main line of “unitized design - CNC cutting - assembly welding - coating composite”. Plasma cutting machines process steel plates and keels, which are then covered with insulation cores and exterior panels, pressed with sealing strips, and pressure-tested before leaving the factory. This process ensures even force distribution during container lifting, preventing local stress concentration that could lead to deformation or cracking, particularly suitable for projects with frequent site turnover, such as Dalian Port expansion and Yingkou High-Tech Zone. For instance, modular housing units used by COSCO Shipping Development in plateau projects achieve double-layer stability through structural interlocking design, increasing space utilization by over 30%.

III. Climate Adaptability Optimization

In response to Liaoning's extreme climate, container houses undergo specialized improvements in insulation, drainage, and wind resistance. For example, a combination of “cold bridge prevention + gutter structure + detachable sunshade + sunroom” addresses plateau cold insulation and efficient drainage issues; professional certification ensures compliance with national building codes, such as the packaged container houses purchased by Sinopec Fourth Construction Co., Ltd., which must meet structural stability requirements across a temperature range of -30°C to 50°C.

IV. Typical Application Scenarios

Container houses are widely used in infrastructure construction, municipal renovations, and port support projects in the Liaozhong-South economic circle. For example, modular housing provided by Beijing Dongfang Guangsha Modular Housing Co., Ltd. for China Railway 22nd Bureau's railway renovation project, and offshore containers produced by Universal Oriental International Container (Qidong) Co., Ltd., both demonstrate advantages in modularity, mobility, and environmental adaptability.
