Technical Advantages

Aluminum’s natural corrosion resistance is enhanced through anodizing or powder coating, providing robust protection against moisture, chemicals, and extreme environments. These treatments extend the lifespan of the extrusions, making them suitable for applications in marine, chemical, and harsh environmental conditions.

Aluminum’s high thermal conductivity allows for efficient heat dissipation, making it ideal for heat exchangers und electronic enclosures. The C-channel design facilitates superior heat transfer, ensuring components remain cool under high-temperature conditions, preventing thermal buildup that can lead to failure.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure dimensional accuracy in custom aluminum C-channel extrusions?

Frigate partners with ISO-certified extrusion plants using high-precision dies and controlled billet temperature profiles to minimize dimensional deviation. We conduct inline profile scanning and offline inspection using digital calipers and CMM tools. This ensures conformance to tight tolerances specified in ASTM B221 or custom GD&T drawings.

Can Frigate supply aluminum C-channels with custom alloy compositions for specific mechanical properties?

Yes, Frigate supports custom alloying through select foundry partners before extrusion. We offer alloy variants like 6082, 6106, or custom tempers for enhanced fatigue strength or corrosion performance. All compositions are validated through material certificates and spectrographic testing.

What surface treatments does Frigate offer for aluminum C-channels used in corrosive environments?

Frigate provides anodizing, powder coating, and chromate conversion coatings to enhance corrosion resistance. Anodizing thickness can be specified from 10 to 25 microns based on application. Treatments comply with MIL-A-8625F and RoHS standards for industrial and marine-grade use.

How does Frigate handle thermal expansion concerns in long aluminum C-channel assemblies?

We provide thermal expansion coefficients with each design, typically around 23 µm/m°C for 6000-series aluminum. For long extrusions, we recommend expansion joints or floating mounts. Frigate’s design team supports stress analysis for temperature-sensitive applications.

What quality checks does Frigate perform on load-bearing aluminum C-channel profiles?

Frigate performs tensile strength tests, yield verification, and bend testing on samples from each batch. We also inspect for twist, camber, and straightness per EN 755-9 standards. All mechanical data is shared via a quality dossier for traceability.
