Common Wall Thickness Parameters
Aluminum tubes with an outer diameter of 60mm typically come in three mainstream wall thicknesses: 1.5mm, 2mm, and 3mm. 1.5mm thin-walled tubes are lightweight (approximately 0.75kg/m), suitable for decorative frames; 2mm balanced tubes (approximately 1kg/m) are mostly used in furniture structures; 3mm thick-walled tubes (approximately 1.5kg/m) are commonly used in load-bearing supports. The thicker the tube, the higher the cost per meter (approximately 20%-30%).
Thickness Affects Three Dimensions
Pressure Resistance: 3mm wall thickness increases bending strength by approximately twice that of 1.5mm.
Processing Characteristics: Thin-walled tubes are easier to cut and bend; thick-walled tubes require specialized tools.
Usage Scenarios: ≥2mm is recommended for outdoor projects; 1.5mm is suitable for indoor decoration.
Purchase Guide: First, measure the required length, then consider the load-bearing requirements. Thin-walled tubes are cost-effective for temporary display racks; thick-walled tubes are recommended for long-term use. Check that the tube ends are smooth and burr-free, and that the surface oxide layer is uniform. For special design needs, please consult the merchant for customization services; some shops offer free tailoring.
