Aluminium Ladders & Structures Suppliers

Aluminium ladders and structures are a standard category of marine and offshore equipment. Both are chosen for the same core reason: aluminium is strong, light, and resistant to corrosion in salt-laden environments. It requires no painting, no galvanising, and far less maintenance than steel. 

We recommend that you check our directory at the bottom of this page to find the right aluminium ladders and structures suppliers for your vessel or project.

Aluminium Ladders on Vessels

On commercial vessels, aluminium ladders serve several different functions. Each type has specific design requirements for rung spacing, handrail height, anti-slip surfaces, and load capacity:

• Fixed vertical ladders: permanent access to cargo holds, tanks, and enclosed compartments
• Accommodation ladders: crew and visitor access between decks or from the vessel to a quay
• Boarding ladders: used during port calls and vessel inspections

Aluminium is 55 to 67 per cent lighter than steel of equal strength, which matters on vessels where topside weight affects stability. Anti-slip surfaces – embossed rungs, perforated treads, or rubber strips – are standard on marine-grade units. 

Most ladders can be custom-manufactured to fit exact dimensions, and class society certification is available from reputable suppliers of aluminium marine ladders and structures.

Aluminium Structures

On offshore vessels and platforms, aluminium structures include helidecks, living quarters, gangways, handrail systems, and modular support frames.

Aluminium helidecks are 50 to 65 per cent lighter than steel equivalents. They are corrosion-resistant, require no surface treatment, and carry class approval from DNV, ABS, BV, LR, and similar societies. The same weight and maintenance advantages apply to gangways, handrail systems, and modular offshore modules.

Experienced aluminium structures suppliers offer design, fabrication, and delivery as a package. Structures typically arrive pre-assembled or in flat-pack form for on-site assembly.

What to Look for in a Supplier

A fixed hold ladder and an offshore helideck are very different products. If you are looking for aluminium ladders, check if the supplier has:

• Custom fabrication capability
• Relevant class society approvals
• Experience with marine-grade alloys
• If you are looking for structural equipment, check if a supplier can provide:
• Engineering and design support
• Compliance with applicable standards (CAP 437 for helidecks, NORSOK for offshore structures)
• Delivery to a shipyard or offshore location

RecordsMarine lists verified providers across both categories. Our team has assessed each company in the directory for product range, certification, and delivery capability.

Frequently Asked Questions

Do suppliers typically stock standard sizes, or is everything made to order? 

It depends on the product. Standard ladder sizes and basic handrail systems are often available from stock. Custom dimensions, helidecks, and structural assemblies are made to order and require a technical specification before quoting.

Can one supplier cover both aluminium ladders and structural equipment? 

Some can, some cannot. Ladder specialists and structural fabricators are often separate businesses. If you need both, RecordsMarine can help you identify providers who cover the full range or connect you with specialists for each product type.

How do I find a supplier who delivers to my port or shipyard? 

Use the directory below. Providers are listed with their geographic coverage and service areas. Filter by location to find a supplier who can deliver to your next port of call or dry-dock location.

What should I send to a supplier to get a quote? 

For ladders: dimensions, vessel type, class society, and any anti-slip or certification requirements. For structures: a full technical specification including load requirements, applicable standards, and installation location.

How long does the procurement of custom aluminium structures take? 

Standard ladders can be delivered within a few weeks. Custom structures such as helidecks and gangways require longer lead times for design, fabrication, and testing.
