Aluminum square tube

Aluminum square tube

Aluminum and aluminum alloy square or rectangular profile tubes are hollow tubes with square or rectangular cross-sections. They are mainly produced through a single hot extrusion process. The main difference between these tubes and standard tubes lies in the shape of the cross-section, which directly determines their unique advantages in terms of structure, connection methods, and decoration.

Common Alloy Designations and Characteristics

Common application scenarios

Common extruded square tube

Conventional hot extrusion molding, used for most structural components.

6063/T5: Commonly used, with moderate strength, excellent extrusion and surface treatment properties, suitable for doors, windows, and decoration.

6061/T6: High strength, used for high-load structures, such as mechanical equipment frames, vehicle modification anti-roll frames.

3003: Good corrosion resistance, high plasticity, often used in decoration, furniture, and other light-load scenarios.

Architecture and decoration: Door and window curtain wall frames, canopy and sunroom frameworks, indoor and outdoor railings, stair handrails, decorative partitions. Industrial and mechanical equipment: Various non-standard equipment frames, production line workbenches/suction lines supports, robot guardrails, storage shelves.

Transportation and logistics: Bus/truck cabin frames, vehicle chassis subframes, luggage racks, container components.

Precision/thin-walled square tube

The dimensions are highly precise, the wall thickness is uniform, and the surface is smooth and clean.

It is mainly made of 6061 or 6063 through precise extrusion or cold drawing, and is used for high-end display stands and the structures of precision instruments.

Furniture and Display: Modern style tables, chairs, beds, commercial store display cabinets, shelves, exhibition truss systems.

Large-diameter thick-walled square tube

The cross-section is large and the bearing capacity is strong.

Use 6061-T6 or 6082 instead, for large machinery, bridges, and main structural supports of buildings.

Other fields: Fitness equipment frames, solar photovoltaic supports, agricultural greenhouse frame structures, etc.
