Aluminum Extrusion Finishes
Surface finishes protect extruded aluminum parts from corrosion and wear while improving appearance. View our finishing methods listed below. We're happy to discuss additional options to meet your specific requirements.
Anodizing
Creates a protective oxide layer that stops corrosion and provides electrical insulation. Available in natural, black, and colored finishes for architectural and electronic applications.
Powder Coating
Dry powder coating baked onto aluminum for tough, colorful finish. Resists scratches, UV rays, and chemicals. Wide color range for outdoor and decorative uses.
Electrophoresis
Uniform coating process using electric current to deposit paint evenly on complex shapes. Provides smooth finish and good corrosion protection for automotive parts.
Brushed Finish
Mechanical brushing creates directional grain texture that hides scratches and fingerprints. Popular for consumer electronics, appliances, and architectural trim with metal look.
Bead Blasting
High-pressure glass beads create uniform matte surface texture. Removes machining marks and provides consistent appearance for precision parts and decorative applications.
Painting
Liquid paint application offers unlimited color choices at low cost. Good for prototypes, small batches, and applications where color matching is important.
Quality You Can Trust
Quality is built into every step of our aluminum extrusion process. With ISO-certified production facilities and over 70 extrusion and inspection machines, we deliver parts that meet high standards in accuracy and finish.
Dimensional and Tolerance Checks
We measure key dimensions like cross-section width, height, wall thickness, total length, straightness, flatness, perpendicularity, and fit of holes or slots. Inspection tools include calipers, micrometers, height gauges, and coordinate measuring machines (CMM).
Surface Inspection
All profiles are checked for scratches, dents, cracks, air bubbles, burrs, extrusion lines, and deformation. Lighting and magnification are used to spot fine surface issues.
Material and Performance Testing
On request, we provide test results for strength and hardness, as well as RoHS reports and material certificates, depending on project needs.

Aluminum Extrusion Process
Aluminum extrusion is the process of pushing a heated aluminum billet through a custom die to form profiles with a specific cross-sectional shape. We follow a standard, proven production flow:
1
Die Machining
Solid, hollow, or semi-hollow dies are machined according to specifications
2
Billet Preheating
Aluminum billets are heated to 400–500°C for optimal extrusion
3
Extrusion
Heated aluminum is pushed through the die using direct or indirect methods
4
Cooling & Stretching
Extruded profiles are cooled and stretched to straighten and relieve stress
5
Cutting & Finishing
Profiles are cut to size and undergo surface finishing as needed
6
Inspection & Packaging
Final inspection and packaging before delivery

Frequently Asked Questions
What's the typical tolerance range for custom aluminum extrusions?
Tighter tolerances cost more to manufacture. Precision tooling and extra inspection steps increase production expenses. Pick tolerances that match your project needs. Standard tolerances work for most applications and keep costs down.
We follow ISO 9001-C standards. Critical dimensions are controlled within ±0.1 mm, while other dimensions are held to ±0.15 mm. We help you pick the right tolerance specification that works for your custom aluminum extrusion project without paying for precision you don't need.
What factors determine the wall thickness of custom aluminum extrusions?
The wall thickness of an aluminum extrusion depends on several practical considerations:
- Aluminum Grade – Softer alloys may need thicker walls for strength, while stronger alloys can support thinner sections.
- Profile Design – Shapes with deep channels, curves, or unsupported spans may require more thickness for stability.
- Press Capability – The size and tonnage of the press influence how thin or thick a section can be reliably formed.
- Surface Finishing – Coatings or anodizing may affect minimum wall thickness to avoid distortion or uneven treatment.
- Dimensional Tolerance – Stricter tolerance limits often lead to thicker walls to ensure consistent output during cutting or machining.
What wall thickness is generally recommended for custom aluminum extrusions?
A typical recommended wall thickness falls between 1.0 mm and 2.5 mm.
- For structural or load-bearing parts, thicker walls (2.0 mm or more) offer better strength and rigidity.
- For lightweight or decorative components, thinner walls (around 1.0 mm) are often sufficient.
- Minimum feasible thickness also depends on the alloy, shape complexity, and press capacity.
The final choice should balance mechanical needs, weight, and cost, based on how the extruded aluminum part will be used.
Do you support prototyping for aluminum extrusion projects?
Yes, we provide prototyping and small-batch aluminum extrusion services. We can produce sample parts for testing and validation before full production runs.
Our prototyping service helps you:
- Test fit and function before committing to large quantities
- Verify dimensions and tolerances meet your specs
- Evaluate surface finishes and material properties
- Make design changes early in the development process
