Frequently Asked Questions (FAQ)
Q1: How does the structural strength of an aluminium square hollow bar compare to round hollow bars?
A: While both profiles offer excellent strength-to-weight ratios, the aluminium square hollow bar demonstrates particular advantages in bending resistance along its principal axes and provides superior torsional stability compared to round sections of equivalent weight. The flat surfaces of the aluminium square hollow bar also offer better resistance against local buckling in compression applications, making it particularly suitable for column-type loading scenarios in structural frameworks.
Q2: What are the standard sizing conventions for aluminium square hollow bars?
A: The aluminium square hollow bar is typically specified by its external width across flats and wall thickness. Standard sizes vary by manufacturer and application requirements, with common widths ranging from smaller sections (25mm) for furniture and light structural applications to larger industrial sizes (150mm+) for heavy framing. Custom dimensions can often be produced to meet specific project requirements through specialized extrusion processes.
Q3: Can aluminium square hollow bars be welded, and are there special considerations?
A: Yes, the aluminium square hollow bar can be welded using standard techniques such as TIG or MIG welding with appropriate filler materials. However, the thermal conductivity of aluminium requires higher heat input compared to steel, and proper cleaning before welding is essential to ensure sound welds. The square geometry actually facilitates fixture and alignment during welding operations compared to cylindrical sections, though distortion control remains an important consideration in fabrication.
Q4: How does the cost of aluminium square hollow bar compare to steel structural sections?
A: While the initial material cost of the aluminium square hollow bar is typically higher than equivalent steel sections, the total installed cost often proves competitive when considering the complete project economics. The reduced weight of the aluminium square hollow bar lowers transportation and handling costs, while the minimal maintenance requirements and corrosion resistance eliminate ongoing painting or protective treatments, providing significant lifecycle cost savings in many applications.
Q5: What surface treatment options are available for aluminium square hollow bars?
A: The aluminium square hollow bar can be enhanced with various surface treatments including anodizing for improved corrosion resistance and color options, powder coating for decorative finishes and additional protection, or mechanical finishing such as brushing or polishing for aesthetic applications. The flat surfaces of the aluminium square hollow bar are particularly well-suited to these finishing processes, ensuring uniform results across all faces.
