Hengshui Mobile House Container

The materials of Hengshui mobile house containers mainly consist of color-steel sandwich panels, with high-strength light steel being commonly used for the main frame. Some products utilize galvanized steel, and the wall panel cores include materials such as rock wool, glass wool, or polyurethane. Here is a detailed analysis:

1. Application of Color-Steel Sandwich Panels
Mobile house containers produced in the Hengshui area widely adopt color-steel sandwich panels as the primary material. For example, products from Hebei Wangjiang Shengda Steel Structure Engineering Co., Ltd. clearly label the material as 'color steel', with product categories including 'color-steel tiles' and product descriptions mentioning 'material: color-steel sandwich panel'. Color-steel sandwich panels are composed of two layers of colored coated steel sheets with an intermediate core material, offering characteristics such as light weight, high strength, fire resistance, and thermal insulation, making them suitable for temporary buildings, office buildings, hospitals, and other scenarios.

2. Main Frame Materials and Processes
The main frame of mobile houses typically employs high-strength light steel (such as Q235B or Q355 steel), with a thickness generally not less than 2.0mm to ensure structural stability. Some products undergo galvanizing treatment or are sprayed with high-quality anti-corrosion paint to enhance corrosion resistance. For instance, industry reports indicate that container houses using high-standard galvanized steel and polyurethane continuous foaming processes can increase structural lifespan by over 50%.

3. Diversity of Wall Panel Cores
The choice of wall panel core material directly affects the fire resistance and thermal insulation properties of the house. In products from the Hengshui area, core materials may include rock wool, glass wool, or polyurethane. Rock wool and glass wool offer excellent fire resistance (Class A non-combustible), while polyurethane is renowned for its high thermal insulation efficiency, although its flame retardancy needs to be controlled through processes.

4. Other Key Materials and Processes
The roof load-bearing capacity of the house must meet snow and wind load requirements, typically achieved through enhanced structural design. Sealing and waterproofing performance rely on high-quality sealing strips and connection processes. Additionally, some products adopt a process of sandblasting for rust removal followed by spraying with anti-corrosion paint to further extend service life.
