Thin-Wall Extruded Lightweight Aluminum Square Tube for Office and Household Furniture Framework Parts

Product Description

Product Description

Product Overview

Our aluminum square tube and aluminum rectangular tube are high-precision extruded aluminum profile products manufactured by advanced hot extrusion and cold finishing technology. Adopting premium aluminum alloy raw materials including 6061, 6063, 7075, 5052 and 3003, the products feature uniform wall thickness, flat and smooth surface, precise dimensional tolerance and stable mechanical performance. All profiles are free of burrs, deformation and surface defects, ensuring excellent processing performance and assembly accuracy. Widely applicable for construction decoration, mechanical frames, equipment brackets, furniture structures, new energy equipment and municipal engineering projects.

Lightweight & High Strength

Aluminum square and rectangular tubes own outstanding strength-to-weight ratio. They are much lighter than steel profiles while maintaining good rigidity and load-bearing capacity, effectively reducing overall structural weight and transportation cost.

Excellent Corrosion Resistance

The aluminum alloy material forms a natural anti-oxidation layer, and can be further treated with anodizing, powder coating, sandblasting and polishing. It performs well in anti-rust, anti-oxidation and weather resistance, suitable for long-term outdoor and industrial environment use.

Precise Dimension & Good Flatness

Produced by professional extrusion molds and cold calibration process, the square tube and rectangular tube have straight edges, flat surfaces, consistent wall thickness and tight tolerance. No deformation after cutting, bending, drilling and CNC processing.

Easy Processing & Installation

The aluminum profile is easy to cut, weld, bend, punch and assemble. With high surface smoothness, it requires little secondary polishing, greatly improving construction and production efficiency.

Durable & Recyclable

Aluminum alloy materials have stable chemical properties, long service life and 100% recyclable features, meeting environmental protection and green engineering standards.

Application Domain

Our aluminum square tubes and rectangular tubes are widely applied in multiple industries. In architectural decoration, they are ideal for curtain wall frames, door and window frames, handrails and indoor & outdoor decorative structures, featuring excellent weather resistance for long-term service. In industrial fields, they serve as high-precision support frames, equipment bases and structural parts for automated machinery and industrial devices. Thanks to lightweight and easy-processing performance, they are commonly used for household and office furniture frames, display racks and various supporting structures. They are also widely adopted in new energy equipment for solar brackets, energy storage device structural components to reduce equipment load. Besides, they fit municipal and outdoor engineering facilities, advertising frames and public landscape structures with great anti-rust and weatherproof capacity. Additionally, the corrosion-resistant tubes are applicable for agricultural machinery parts to adapt to humid and outdoor working environments.
