Main Features

Pre-fabricated Modular Construction: Our Helideck packages are modularly designed for easy onsite assembly, inspection, and installation. The helideck is completely bolted together so no onsite welding is necessary.

Lightweight: Our helideck system weighs approximately half that of a comparably sized steel helideck.

Maintenance Free: Our systems are designed to be a maintenance free solution, requiring only necessary inspections according to applicable regulations. No chipping paint, re-painting, grinding, expensive upkeep etc.

Fast Assembly: The modular design allows for timely assembly and installation in approx. 30 days under normal working conditions.

High Friction Surface: Our unique extruded aluminum profile with a serrated surface and cross-milling, creates an optimum friction value to ensure helideck surface complies with friction requirements without the use of a landing net.

Cost Efficient: Since our helidecks are relatively maintenance free with an estimated 30+ year life-span, it is a financially wise solution for your helideck needs. Also bear in mind the scrap value of aluminium upon termination of use.

Long lifespan: Our helideck was carefully designed with long-term service in mind. Using the right design and proper materials, our helidecks are fit for approximately 30+ years of service.

Environmentally Friendly: The aluminium helideck is 100% recyclable, and requires zero painting and grinding, thus preventing further use of time, money, and valuable resources.
