WHY THIS EXISTS
An aluminium deck on a steel support frame is half the answer. The deck saves topside weight. The frame underneath it doesn't.
Carrying the same engineering logic one level down delivers compounding savings: less topside weight cascading through every supporting structure below, fewer welds in the load path, no painting or blasting in the fabrication schedule, and no corrosion to manage over the asset's life.
We design, build and install support frames using the same modular fabrication process that underpins every XE and XD deck we ship.
MODULAR FABRICATION
Every support frame is fabricated to tolerances tight enough that components fit first time on site. Parts are packed directly into shipping containers and sent to platform, no trial assembly, no dismantling, no rework.
A typical 22m support frame assembles on site in around one week. The steel equivalent takes 8 to 12 weeks of fabrication, blasting and painting before it's ready to install.
Compatible with XE Enhanced Safety™ and XD Standard helidecks. Specified as a complete deck-and-frame package, or supplied separately to retrofit an existing deck onto a new structure.

ENGINEERING ADVANTAGES
1. 60% lighter than steel
A direct weight reduction at the support frame level cascades through foundations, lifting requirements and installation cost.
2. One-week assembly
A typical 22m frame assembles in around a week. The steel equivalent takes two to three months end-to-end.
3. No painting, no blasting, no corrosion
Marine-grade aluminium doesn't need a protective coating system. The frame ships finished and stays finished for the life of the asset.
4. Reusable, recyclable
Bolted construction means the frame can be dismantled, relocated and reinstalled on a different platform. End-of-life material is fully recyclable.
