Key Takeaways
- Sizing: The size and wall thickness of the square tube should be chosen based on the structural requirements and load-bearing capacity needed for the specific application.
- Material Selection: The choice of material affects the strength, weight, and cost of the tube. Mild steel is often used for general construction, while stainless steel is selected for corrosion resistance.
- Fabrication: Cold forming allows for precise dimensions and surface finishes, making HSS square tubes suitable for a wide range of structural applications.
- Calculations: Understanding how to calculate the moment of inertia and section modulus is crucial for engineers when designing structures to ensure they can support the expected loads.
This table serves as a comprehensive guide for understanding the specifications and considerations for cold-formed HSS square tubes, making it useful for engineers, architects, and fabricators in the industry.
