Galvanized Pipes for Container Houses

Galvanized pipes are commonly used as framework materials in the manufacturing of small and medium-sized container houses, suitable for non-heavy-duty and temporary applications. Specifications should be selected according to the purpose, and construction specifications must be strictly followed.

Application Scenarios

1. Framework and Support Structures
   The container framework is the core load-bearing component, needing to withstand stacking pressure. Galvanized square and rectangular pipes are often used for corner posts, top beams, bottom beams, and sidewall columns due to their excellent bending and torsion resistance. For example, the frameworks of storage containers or temporary housing often use such pipes to ensure structural stability.
2. Bottom Beams and Floor Support
   The floor must withstand the weight of forklifts and cargo. Galvanized pipes, used as bottom cross and longitudinal beams, provide uniform support. Their corrosion resistance prevents rusting caused by water accumulation or humid environments, extending the lifespan of the container.
3. Door Frames and Lock Bars
   Door frames require frequent opening and closing while ensuring airtightness. Galvanized steel pipes, with their high dimensional accuracy and ease of processing, are ideal materials for door frames. Lock bars and other hardware components also use galvanized pipes to ensure long-term flexibility and reliability.

Selection Requirements

1. Specification Selection
   Hot-dip galvanized square pipes are preferred, with wall thickness determined by the application: load-bearing parts (such as columns and beams) require thick-walled square pipes over 8mm; frames can use 4-6mm wall thickness. Thin-walled pipes are prone to framework fractures and should be avoided.
2. Material Standards
   They must comply with GB/T 6728 (Structural Cold-Formed Hollow Section Steel) and GB/T 3091 (Welded Steel Pipes for Low-Pressure Fluid Transportation) standards to ensure material strength meets requirements. Poor-quality thin-walled square pipes may pose safety risks due to insufficient strength.
3. Construction Specifications
   The zinc layer at welding points should be ground off, and galvanizing or anti-corrosion paint should be promptly applied after welding to ensure overall corrosion resistance. Framework assembly must be secure and comply with container structural safety standards to prevent deformation due to loose connections.

Usage Limitations

Galvanized square pipes are more suitable for small and medium-sized, non-heavy-duty, and temporary container frameworks. For large heavy-duty containers (such as ocean shipping containers), which endure long-term high-intensity impacts and heavy loads, specialized container section steel is recommended for its superior mechanical properties and durability.
