Heavy Duty 6061 Profile
Structural aluminum extrusion in 6061-T6 temper with reinforced wall sections and precision tolerances. Engineered for industrial framing, automated equipment, and high-load support systems. Available with custom machining and surface finishing through integrated production lines.
Load capacity
- 80x80 series: 12.7 cm³ section modulus
- 100x100 series: 22.4 cm³ section modulus
- Supports up to 1200 kg/m uniform load (simply supported)
Material consistency
- 6061-T6 with Mg (0.8–1.2%) and Si (0.4–0.8%)
- ASTM B221 compliant
- Uniform mechanical properties across batches
Dimensional stability
- Straightness: ≤ 0.5 mm/m
- Twist: ≤ 0.3 mm/m
- Custom cut lengths with ±0.2 mm tolerance
Core Advantages
Integrated manufacturing chain
From mold design and extrusion to CNC machining, anodizing/powder coating, and assembly — all managed in-house across three production bases (Shanghai, Anhui, Jiangsu). Reduces lead time and ensures quality control.
Surface preparation
Degreased and chemically passivated before finishing. Anodic coating thickness up to 25 μm (Class AA25) per MIL-A-8625. Powder coating available in RAL colors with uniform film build.
Precision machining
CNC drilling, tapping, milling, and counterboring with ±0.1 mm positional accuracy. Thread-forming and helical inserts supported for high-strength joints.
Corrosion resistance
6061 alloy provides natural oxidation resistance. Anodized surfaces withstand 500+ hours salt spray (ASTM B117). Suitable for indoor and protected outdoor environments.

Processing & Assembly Notes
- Recommended tapping torque for M8 threads: 18–22 N·m. Use thread-forming screws for blind holes to reduce stress.
- For anodized profiles, use neutral pH cleaners (6–8). Avoid acidic or alkaline agents that may degrade the coating.
- Welding: use ER4043 or ER5356 filler wire. Post-weld heat treatment (PWHT) is required to restore T6 properties.
- Maximum continuous operating temperature: 150 °C. Strength reduction occurs above this threshold.
- Storage: keep profiles dry and covered. Avoid direct contact with dissimilar metals (e.g., copper, bare steel) to prevent galvanic corrosion.
Frequently Asked Questions
Under a simply supported span of 2.0 m with uniform load, the 100×100×5 mm profile (section modulus 22.4 cm³) supports approximately 1800 kg at yield strength (276 MPa). For point loads at mid-span, reduce capacity by 50%. Always consult engineering calculations for your specific configuration.
Yes. Huishuo operates 3-axis and 5-axis CNC machining centers for drilling, tapping, milling, and counterboring. We also offer profile cutting to exact lengths with ±0.2 mm tolerance. Submit 2D/3D drawings for a process review.
Mill finish ships within 7–10 days. Anodizing (clear/black) adds 3–5 days; powder coating (any RAL) adds 5–7 days. All surface treatment lines are in-house, reducing outsourcing delays. Minimum order quantity for custom colors: 500 kg.
Use anti-seize lubricant (nickel-based or copper-based) on threads, or specify PTFE-coated fasteners. For anodized profiles, apply a dry-film lubricant to mating surfaces to reduce friction and prevent aluminium transfer
