Container House Fixed Screws

Container house fixed screws should be selected based on specific application scenarios and structural requirements. Common types include high-strength turnbuckle screws, carbon steel hex head bolts, self-drilling screws, and dedicated frame screws, among others. The following provides an overview of screw types, application scenarios, and selection considerations:

1. Fixing of Main Container Structure
The main frame connections of container houses typically employ high-strength turnbuckle screws or carbon steel hex head bolts. For example, a Qingdao-based company offers container lashing rod fasteners, including high-strength turnbuckle twist locks made of carbon steel, suitable for locking and fixing container corner fittings to the frame. These screws can withstand significant tension, ensuring structural stability. Such screws must comply with standard part specifications, and when custom-processed, specific part numbers, materials, and brands (such as "Deyi Weicheng") must be clearly defined. The minimum order quantity is usually over 500 pieces, suitable for large-scale projects.

2. Fixing of Roof and Wall Materials
If the container house uses metal roofing or color-steel plate walls, self-drilling screws or concealed roof screws are required. For instance, a Hebei-based company produces 1/4-inch J-hook roof bolts with triangular washers, suitable for fixing corrugated sheets; a Jiangsu-based company provides rust-resistant countersunk wood screws for connecting wooden roofs or insulation boards. These screws must have rust-resistant properties (such as galvanized treatment) and be selected according to material thickness (e.g., M4.8*16mm).

3. Modular Combination and Movable Components
For variable container modules (such as flip-up wall panels or sliding structures), removable screws or quick-assembly structures are necessary. For example, a Shanghai-based company offers screws for tempered glass container mobile houses that support easy disassembly and reassembly, suitable for temporary office or commercial scenarios. These screws must balance strength and convenience, typically using stainless steel or carbon steel materials, and are equipped with decorative caps to enhance aesthetics.

4. Reinforcement in Special Scenarios
In areas with high seismic resistance requirements (≤8 degrees) or cantilevered structures, high-strength anchor bolts or J-bolts are required. For example, a Handan-based company provides 7-shaped streetlight welded embedded anchor bolts for roof anchoring; a Foshan-based company produces fiberglass anchor bolts that are corrosion-resistant and easy to cut, suitable for extreme environments such as mine roof support. These screws must pass tension tests to ensure their load-bearing capacity meets design life requirements (e.g., 50 years).

Core Selection Principles:

• Material Matching: Steel containers should prioritize carbon steel screws, while aluminum structures require lightweight stainless steel screws;
• Environmental Adaptability: Humid areas require galvanized or stainless steel screws, while coastal areas must consider salt spray corrosion;
• Installation Convenience: For modular houses, self-tapping screws or quick-assembly structures are recommended to reduce on-site processing steps.
