We have an extensive track record in designing, producing and installing large structures in aluminium alloy. In many cases, these structures are unique and 'world-firsts', requiring extensive applied research in material technology, joint configurations, fatigue design and fastening methods.
The usual drivers for encouraging a switch from steel to aluminium are:

• Lower maintenance cost - with marine-grade aluminium alloys, corrosion is reduced to insignificant levels and no painting is required
• Lower weight - aluminium's exceptional strength-to-weight ratio means weight savings of 50% to 70% over equivalent steel structures
• Lower cost - long-term cost reduction through maintenance cost savings; customers also achieve initial cost savings at installation owing to lower lift costs, easier fabrication and faster installation
• Longer life span - the durability of the alloy means that it usually outlasts the structure it is placed on and can be reused on new platforms
• Recycling - aluminium has high residual value and is genuinely and economically recyclable. Recycling aluminium only requires 5% of its formation energy
