Marine &
Offshore
Marine environments demand the highest corrosion resistance. CANEX produces structural aluminum profiles and die castings backed by QUALICOAT Seaside certification — the highest standard for coastal and salt-spray durability — for vessels, docks, and offshore structures.
the Harshest Environments
Salt spray, humidity, and continuous immersion are the defining challenges of marine environments — and they demand aluminum profiles with the highest corrosion resistance standards available. CANEX is one of a select group of manufacturers holding QUALICOAT Seaside certification, the most stringent standard for aluminum coating in coastal and marine applications.
CANEX supplies structural marine frame profiles, deck and handrail sections, vessel interior profiles, pontoon and dock sections, and offshore equipment housings — in marine-grade alloys with QUALICOAT Seaside powder coating or thick-film anodizing.
Our CE Mark certification ensures CANEX profiles meet EU requirements for marine structural applications on European-flagged vessels and offshore installations.

Questions
What aluminum alloy does CANEX recommend for marine applications?
For marine structural applications, CANEX recommends 5083-H111 — the internationally recognised marine-grade alloy with exceptional seawater corrosion resistance. For profiles where higher extrudability or surface finish is needed, 6061-T6 and 6063-T6 are used with appropriate QUALICOAT Seaside coating or thick-film anodizing.
Does CANEX hold QUALICOAT Seaside certification for marine profiles?
Yes. CANEX holds QUALICOAT Seaside certification — the highest QUALICOAT level — for our powder coating application. This confirms our coated profiles meet the most demanding corrosion resistance requirements for coastal, marine, and salt-spray environments. Issued by Dedal Attestation & Certification.
What is better for marine profiles — anodizing or powder coating?
Both finishes are used in marine applications. Anodizing (minimum 25 micron for marine) provides excellent corrosion resistance. QUALICOAT Seaside powder coating provides superior colour retention, UV resistance, and impact protection — preferred for visible architectural and deck elements. CANEX offers both options to your specification.
What are the corrosion resistance specifications for CANEX marine profiles?
CANEX marine profiles with QUALICOAT Seaside powder coating achieve over 1000 hours salt spray resistance (ASTM B117 / ISO 9227) — the threshold for Seaside certification. Anodized profiles are supplied to a minimum 25 micron coating thickness for marine applications.
Does CANEX hold CE Mark for marine aluminum profiles?
Yes. CANEX aluminum profiles carry the CE Mark, confirming conformity with applicable EU product standards — required for specification on EU offshore projects, marine infrastructure, and EU-flagged vessel construction.
Can CANEX supply custom marine aluminum profile cross-sections?
Yes. CANEX offers in-house die design and manufacture for custom marine profile cross-sections. Submit your DXF or CAD drawing and our engineers will review for extrudability and deliver first article samples within 4–6 weeks of die approval.
Send us your marine profile requirements or specification drawings and our team will respond within 48 hours.
