Rectangular Hollow Aluminum Profile: Hollow Rectangular Aluminum Tube for Structural Engineering
Rectangular hollow aluminum profile is a hollow rectangular tubular aluminum extrusion product, also known as rectangular aluminum tube. With a closed hollow rectangular structure, this profile features light weight, high torsional rigidity, strong compression resistance, and excellent overall stability. Rectangular hollow aluminum profiles are core structural materials widely used in building frames, mechanical supports, curtain wall engineering, and industrial equipment structures.
Structural Advantages
Different from solid aluminum profiles, rectangular hollow aluminum profiles adopt a hollow closed structure, which greatly reduces self-weight while ensuring high structural strength. The four-sided closed rectangular design provides excellent bending resistance and torsion resistance, not easy to deform under long-term load. The inner and outer surfaces are smooth and flat, easy for surface treatment and welding assembly.
Key Performance Benefits
- Lightweight & High Strength: Hollow structure reduces weight without losing structural stability.
- Strong Pressure Resistance: Closed rectangular structure improves overall load-bearing capacity.
- Anti-deformation & Anti-torsion: Excellent stability for long-span frame structures.
- Perfect Corrosion Resistance: Alloy material resists rust, oxidation and atmospheric erosion.
- High Decorative Value: Neat rectangular shape suits architectural facade decoration.
Wide Application Range
Rectangular hollow aluminum profiles are widely used in building curtain wall frames, industrial equipment support frames, exhibition stand structures, furniture aluminum frames, vehicle body structures, pipeline supports, and outdoor engineering structures. It is the preferred hollow profile for modern lightweight green building systems.
Material & Processing
Most rectangular hollow aluminum profiles adopt 6063 and 6061 aluminum alloy, with precise extrusion sizing. The products support anodizing, electrophoresis, powder coating and fluorocarbon surface treatments. Customized width, height, wall thickness and cutting lengths are available for different engineering needs.
