XD Standard Helidecks

XD Standard Helidecks

Our XD Standard helideck is an all-aluminium helideck with all the features of the XE Enhanced Safety helideck but without its passive fire suppression system. The top surface of this helideck is flat and non-perforated and incorporates a non-slip pattern which is etched and milled into the decking. The decks are fully pre-fabricated and shipped in containers to you for local assembly under our supervision.

XD Standard Helidecks

Modular Design

Weld free, modular construction ensures faster fabrication. Bolted connections allow quick assembly, fewer inspection hold-points and easy replacement of damaged sections. We manufacture the deck and ship them in containers to wherever you like. Our supervisors will make site assembly an easy task.

Modular sections mean the deck is easier and lighter to transport, assemble and lift into place.

PRECISION FABRICATION

Fabrication and Assembly

Weld free, modular construction ensures faster fabrication. Bolted connections allow quick assembly, fewer inspection hold-points and easy replacement of damaged sections. We manufacture the deck and ship them in containers to wherever you like. Our supervisors will make site assembly an easy task.
A typical large helideck can be assembled in approximately three weeks. Contrast this with a usual steel helideck assembly time of three months.

Cost Effective

An aluminium helideck is a good investment. Not only will its residual value appreciate over time, it can be reused several times, as it will usually outlast the structure it is initially placed on. The purchase of an aluminium deck is also low in comparison to steel since the higher per-ton cost of aluminium is offset by the lower tonnage used and the savings in fabrication time.

PERFORMANCE

Fire Resistant

Both models of our helidecks have been live fire tested in the presence of major Classification bodies and certified ‘equal to steel’.

Stay Dry, Non-slip Surface

No weld distortions on surface; the aluminium decking top is serrated and cross-milled and tested to provide a permanent non-slip grip according to UK CAA CAP437 requirements. This non-slip surface is excellent and will last the lifetime of the deck and there is no need for further re-testing of the surface for the life of the deck.
