Container Mobile House Main Frame

The types of main frames for container mobile houses are diverse, and prices vary depending on materials, specifications, and functions. Here is a popular science explanation from three aspects: common types, price ranges, and material characteristics:

Common Types and Prices
Currently, the mainstream main frames for container mobile houses on the market can be divided into two categories: standardized frames and customized frames. Standardized frames are mainly in universal sizes. For example, the galvanized steel frame provided by Jiangsu Tangcheng adopts a high-strength load-bearing structure with wind resistance and rust prevention characteristics, priced at approximately ¥140.0; the CE-certified customized box steel structure frame from Shanghai Xiban is suitable for villa assembly or mobile activity houses, priced at approximately ¥113.0; the C-shaped steel frame from Suzhou Gansu is designed for on-site living scenarios, coming with cold storage or quick-assembly activity panel houses, with a包邮 (free shipping) price of ¥741.0.
Customized frames are usually designed according to special requirements. For example, the special equipment container frame from Guangzhou Jinge adopts thickened steel plates, suitable for maritime transportation or explosion-proof and flame-retardant scenarios, with a price as high as ¥20786.0; the adjustable activity house frame from Foshan Jingcheng supports flexible assembly, priced at ¥669.75; the keel-type frame from Suzhou Dongji emphasizes easy disassembly, priced at ¥1045.0. The price differences mainly stem from material thickness, structural complexity, and additional functions (such as explosion-proof and adjustability).

Material Characteristics and Structural Advantages
The core material of the main frame for container mobile houses is a steel frame structure, mainly consisting of galvanized steel or thickened steel plates. Galvanized steel, through surface galvanizing treatment, effectively isolates moisture and oxygen, significantly enhancing rust prevention capabilities, suitable for humid or rainy environments; thickened steel plates enhance load-bearing and impact resistance by increasing material thickness, meeting the needs of heavy equipment or high-security scenarios.
Structurally, the main frame adopts a modular design, fixed by bolts or welding, forming a stable triangular or rectangular load-bearing system. For example, the high-strength load-bearing structure can withstand winds of over 8 levels, the earthquake-resistant design reduces damage from seismic waves to the house, and the corrosion-resistant characteristic extends the service life and reduces maintenance costs.

Purchase Recommendations
When choosing a main frame, it is necessary to comprehensively consider the usage scenario, budget, and long-term costs. If used for temporary on-site housing, standardized frames (such as C-shaped steel or galvanized steel) offer higher cost-effectiveness; if long-term use or extreme environments are required, customized thickened steel plate frames are more reliable. In addition, it is necessary to pay attention to the supplier's qualifications (such as CE certification) and after-sales service to ensure structural safety and convenient later maintenance.
