Established in 1977, Heliport Systems, Inc. plans, designs, and constructs heliports for hospitals, businesses, and the marine industry worldwide. For rooftops, we manufacture a modular, steel and aluminum, Rooftop Heliport System, complete with Heliport Lighting and Heliport Foam Fire Protection. For ships and offshore oil rigs where ultra light weight and immunity from corrosion are essential, we manufacture a prefabricated all-aluminum heliport system. Our services range from - professional site selection; compliance with aeronautics regulations; engineering design; manufacture of helidecks, heliport lighting, and heliport fire protection equipment - to turnkey construction. All services and products are fully insured.
Heliport Systems Inc. manufactures modular, steel and aluminum, high strength to weight, maintenance free heliports complete with state of the art lighting and fire protection. We can design, furnish, and install a permanent, approved, one-helicopter rooftop heliport anywhere in the continental U.S. starting at $410,000. Two and three helicopter sized heliports also are available. Options available for all sizes are automatic snowmelting and rooftop fuelling
