Geodesic Dome Roofs

Aluminum Dome for Aboveground Storage Tanks   


    The HMT Geodesic Dome features a clear-span, all-aluminum, lightweight, corrosion-resistant structure which sets a new standard for performance in aluminum geodesic domes.

    HMT’s unique overlapping-panel design and attention to details at critical locations all result in a cost-effective solution that provides superior protection of your stored product.

    The HMT Geodesic Dome can be installed in-service and its superior design was developed under the guidance of API 650, appendix G and AWWA D-108.

    Key Benefits
    The HMT Geodesic Dome’s advanced technology provides excellent benefits. Here’s how:
  • Most effective leak-protection solution — Engineered for maximum weather-tightness for both new tanks and retrofits
  • Low maintenance cost — Aluminum alloys are corrosion resistant and don’t require painting like steel fixed roofs
  • Emissions reduction — reduces wind-induced vapor loss, aids in odor control and provides significant emission credits; for light products such as gasoline, a dome installed over an EFR can cut emissions by over 90%
  • In-service installation — Can be erected on the ground beside the tank or on an EFR and lifted into place
  • Custom engineered— To accommodate a wide range of spans and loading conditions
    Key Design Features
  • Batten bar and gasket assembly completely encapsulate panel edges for unparallelled sealing
  • Overlapping panels ensure additional protection against weather
  • Hub designed with three levels of sealing to ensure maximum leak protection
  • Hub cover can be easily removed for inspection or adjustment of IFR support chains
  • Options for fixed or sliding rim connections
  • Can easily handle the weight of suspended aluminum internal floating roofs
  • Industry-leading 3D design software for maximum accuracy and shorter design time
