The temper (T5 or T6) defines the strength and workability of your aluminum profiles. Here's a simple breakdown of their real-world impact.
The Core Difference: Cooling Method
T5 (Air-Cooled)
Process: Cooled with air after extrusion, then aged.
Result: Good strength with minimal distortion. Profiles are straighter and easier to fabricate.
Use Case: Ideal for architectural windows, decorative frames, and general industrial structures.
T6 (Water-Quenched)
Process: Rapidly cooled with water, then aged.
Result: Significantly higher strength and hardness.
Trade-off: Higher risk of warping, requiring additional straightening, which increases cost.
Use Case: Essential for high-stress applications like robotics, automotive parts, and heavy-duty frames.
Quick Selection Guide:
Choose T5 for: Best value, ease of fabrication, and superior straightness.
Choose T6 for: Maximum structural strength, when performance is critical.

A triangular aluminum tube is a specially extruded aluminum profile with a three-sided geometric structure. Manufacturers widely use it in outdoor garden projects, landscape decoration, pergolas, fencing systems, greenhouse frames, and modern architectural structures because it combines lightweight strength with excellent weather resistance.
Common aluminum alloy grades include:
6061 aluminum alloy
6063 aluminum alloy
6005 aluminum alloy
These alloys provide excellent corrosion resistance, strong structural performance, and good outdoor durability.
Triangular aluminum tubes offer several advantages:
Lightweight but strong structure
Excellent corrosion resistance
Modern decorative appearance
Good wind resistance
Easy installation
Long service life
Low maintenance cost
Therefore, many landscape designers and construction companies choose aluminum triangular tubing for outdoor applications.
We provide multiple surface finishing options, including:
Powder coating
Anodizing
PVDF coating
Wood grain finish
Sandblasting
Brushed finish
These finishes improve UV resistance, weather durability, and decorative appearance.
Yes. We support customized:
Side dimensions
Wall thickness
Tube length
Surface color
Hole patterns
Special extrusion designs
Custom aluminum extrusion services help meet different outdoor garden and architectural project requirements.
Yes. Aluminum naturally forms a protective oxide layer that resists corrosion. In addition, anodized and powder-coated aluminum tubes provide excellent resistance against rain, sunlight, humidity, and temperature changes.
Therefore, triangular aluminum tubes work very well for long-term outdoor applications.
Common wall thickness ranges include:
1.0\text{ mm}\sim5.0\text{ mm}
We can also manufacture customized thicknesses according to project specifications.
Triangular aluminum extrusion tubes are widely used in:
Garden pergolas
Outdoor decorative structures
Landscape architecture
Greenhouse frames
Fence systems
Outdoor furniture
Sunshade structures
Architectural decoration projects
Yes. Aluminum triangular tubes support various fabrication processes, including:
CNC cutting
Drilling
Welding
Bending
Punching
Surface engraving
Therefore, aluminum extrusion tubes suit many custom fabrication projects.
We strictly control:
Aluminum raw materials
