Container House Self-Assembly Accessories

Container house self-assembly accessories mainly include galvanized thickened frames, assembly frame screws, and quick-assembly corner fittings, among others. Different accessories are provided by different manufacturers and are suitable for various scenarios.

I. Main Accessory Types

1. Galvanized Thickened Frames: As the core supporting structure of container houses, galvanized thickened frames are treated with hot-dip galvanizing, forming a dense zinc layer on the surface that effectively resists environmental corrosion from moisture and salt spray, extending service life. Their thickened design (usually with a wall thickness ≥ 3mm) enhances overall load-bearing capacity, meeting the needs of multi-story house construction, and is suitable for scenarios such as project office buildings and staff dormitories.
2. Assembly Frame Screws: Made of high-strength alloy steel and featuring anti-loosening designs (such as double nuts or spring washers), these screws ensure stable frame connections. Screw specifications must match the frame hole diameters (e.g., M12×30mm), and installation requires the use of an electric wrench to tighten in a diagonal sequence, avoiding local stress concentration that could cause deformation.
3. Quick-Assembly Corner Fittings: Comprising corner brackets, connecting plates, and bolts, these fittings are used for rapid assembly at frame corners. Their pre-drilled design shortens installation time, while the triangular mechanical structure distributes loads, enhancing the house's wind resistance, commonly seen in temporary buildings like storage rooms.

II. Typical Suppliers and Product Features

• Shanghai Jiangyu Steel Structure Co., Ltd.: Provides galvanized thickened frames and matching screws. The frames are made of Q345B steel with a yield strength ≥ 345MPa, complying with the Container House Technical Specification (GB/T 36116-2018). The screws are surface-treated with Dacromet, offering salt spray resistance exceeding 500 hours, suitable for coastal areas.
• Tianjin Jinyu Bairun Mechanical Accessories Co., Ltd.: Specializes in producing quick-assembly corner fittings. Their corner brackets are stamped from 6mm thick steel plates, and the connecting plates are equipped with reinforcing ribs, capable of withstanding a uniformly distributed load of 1.5kN/m², meeting storage stacking demands.

III. Application Scenarios and Selection Recommendations

• Project Office Buildings: Choose accessories with good sound insulation and thermal insulation properties, such as galvanized frames paired with rock wool sandwich panels, and stainless steel screws to reduce corrosion risk.
• Staff Dormitories: Prioritize the convenience of quick-assembly corner fittings, combined with lightweight partition walls, enabling single-room assembly within 4 hours.
• Storage Rooms: Select frames and screws with strong load-bearing capacity, such as Q345B steel frames paired with M16 bolts, ensuring safe cargo stacking.

IV. Installation Precautions
Before installation, check the quantity and specifications of accessories. Use a level during frame assembly to ensure alignment. Screw tightening torque should reach 50-60N·m (adjusted according to screw specifications). After installing corner fittings, conduct a load test to ensure no looseness or deformation.
