Marine Aluminium Extrusions-FAQ's
Which alloys are best for marine aluminium extrusions?
We offer marine-grade 5xxx series alloys such as 5086, 5083 and 6082 for superior corrosion resistance, weldability and fatigue performance.
How does aluminum help with marine weight savings?
Aluminum has up to 55-67% weight savings compared to steel, enhancing fuel efficiency, payload capacity and vessel stability.
Are the marine extrusions weldable?
Yes-marine alloys are highly weldable using standard methods and retain most mechanical properties after welding.
What profile shapes can be customized?
Complex profiles such as hull reinforcements, gratings, railings, ladders, deck frames and structural beams are all available.
What surface finishing options are there for marine use?
Finishes include anodizing, powder coating, brushing and painting, providing both aesthetic appeal and corrosion protection.
Can you provide post-extrusion fabrication?
Yes - we offer CNC machining, welding, cutting, bending and assembly support to deliver installation-ready components.
Do these extrusions withstand long-term saltwater exposure?
Yes - marine-grade alloys degrade minimally (often less than 5% strength loss over long exposures), ensuring longevity.
What are typical applications of marine extrusions?
Used in hull structures, deckhouses, ladders, railings, gratings, boat trailers, windscreen frames and structural components.
Is custom tooling required for new profiles?
We can accommodate both standard and bespoke profiles with competitive tooling solutions and scalable production.
