Aluminum square tube specifications cover a range of side lengths from 8mm to 500mm, with a tolerance accuracy of ±0.02mm. Common classifications are as follows:
By External Dimensions
Small Sizes: Side length 10-50mm (e.g., 10×10mm, 20×20mm), used for decorative moldings and small display racks.
Medium Sizes: Side length 50-200mm (e.g., 60×80mm, 100×150mm), used in architectural decoration and furniture manufacturing.
Large Sizes: Side length > 200mm (e.g., 200×200mm, 300×300mm), used for large building structures and industrial support.
By Wall Thickness
Thin Walls: 0.8-1.5mm, suitable for light-load applications such as interior ceilings and partitions.
Medium-Thick Walls: 1.5-3.0mm, used for medium-load applications such as building facade decoration and balcony railings.
Thick-walled: >3.0mm, capable of withstanding greater pressure, used in heavy-duty applications such as industrial equipment frames and bridge construction.
By Length
Standard Length: 6 meters, convenient for transportation and storage.
Custom Length: Cut to meet project requirements (e.g., 3 meters, 5 meters), reducing on-site splicing and improving construction efficiency.
