Wholesale of Container House Materials

When wholesaling materials for container houses, it is essential to focus on the types and quality standards of structural steel, wall panels, flooring, and supporting systems. The following provides an overview of core materials, common types, and key selection considerations:

I. Core Structural Materials
The load-bearing frames of container houses typically use hot-dip galvanized cold-formed steel, which offers excellent rust and corrosion resistance. The thickness of the steel in main beams and columns directly affects load-bearing capacity. Welding must be full and free of cold welds, and the entire container body should be galvanized or coated with anti-corrosion treatment to ensure safety during lifting, stacking, and transportation. For example, the steel thickness of national standard container frames must meet design load requirements to prevent structural deformation due to insufficient material thickness.

II. Wall and Roof Panel Materials
Composite processing of wall and roof panels is crucial for thermal insulation. Common materials include:

• Rock wool sandwich panels: High fire resistance, suitable for scenarios with strict fire safety requirements;
• Glass wool sandwich panels: Excellent sound insulation, often used in environments requiring noise reduction;
• Polyurethane sandwich panels: Outstanding thermal insulation, ideal for cold regions or long-term use.
  For example, packing-box container houses often use fire-resistant polyurethane sandwich panels to balance thermal insulation and fire safety needs.

III. Flooring and Decorative Materials
Flooring materials must meet requirements for wear resistance and moisture resistance. Common choices include:

• Cement fiber boards: Low cost, suitable for temporary housing;
• Steel-wood composite floors: Comfortable underfoot, ideal for long-term living scenarios.
  Wall and ceiling materials are primarily metal panels or calcium silicate boards, offering both fire resistance and decorative appeal. For example, walls in light steel frame houses can be filled with insulation materials, allowing flexible customization of appearance and layout.

IV. Supporting System Materials
Pre-installed doors, windows, electrical, and plumbing systems require compliant materials:

• Doors and windows: Must have anti-theft and sealing properties, commonly made of aluminum alloy or thermal-break aluminum;
• Electrical systems: Wires and cables must comply with national standards, and distribution boxes must have leakage protection;
• Plumbing pipes: PVC or PPR pipes must be corrosion-resistant, with tightly sealed connections.
  For example, doors and windows in residential containers often feature customized designs to adapt to different climatic conditions.
