Aluminum Geodesic Domes and covers

Geodesic Domes for storage tanks are spherical frame structures that are self-supporting.  The geodesic frame is covered with attractive, aluminum panels. These alloys have a proven history of weather resistance even in the harshest environments in the world. This virtually eliminates the need for periodic maintenance, coatings, or paint for the life of the structure. Each dome is designed with the most modern computer technology to check all loading combinations to ensure safety and integrity under all conditions.

The geodesic dome covers are custom engineered for your unique structure. The self-supporting design allows maximum overhead space utilization and provides interference-free operation for floating roofs and other internals. The aspect ratio of the dome can be selected for your location and specific application, offering a range from a very flat, low profile to a high dome for more internal clearance.

Aluminum domes are less expensive than other materials like steel. This makes them a cost-effective solution for covering large water storage tanks. Our aluminum domes are easy to install, which means that they can be quickly erected over water storage tanks. This is important when time is of the essence, such as in emergency situations

Also, a wide range of accessories (vents, skylights, dormers, hatches, foam connections, etc.) is available to meet all your needs.

UIG’s Geotruss Design and Clear Span Covers and Flat Panel Roofs

EVERDOME® Clear Span Roofs are designed to span long distances without the need for intermediate supports, which reduces the risk of leaks and provides an unobstructed view of the reservoir.

Aluminum clear span roofs are highly durable and can withstand harsh weather conditions such as extreme heat, cold, heavy rain, and snow. 

Despite its strength, aluminum is a lightweight material that makes it easy to install and transport. It is also highly resistant to corrosion, making it an excellent choice for covering reservoirs that contain water.

Overall, aluminum clear span roofs are an ideal choice for covering reservoirs because they provide durability, strength, lightweight design, corrosion resistance, and clear span functionality.

  • EVERDOME® all Aluminum Geodesic Domes and Internal Floating Roof construction provides a virtually maintenance-free structure. The smooth surface of the aluminum dome makes it easy to clean and maintain, reducing the need for repairs and painting.
  • Aluminum geodesic domes can be customized to suit different sizes and shapes of tanks, making them a the best option for water storage tanks. These large diameter tank covers are designed to AWWA D108-10 standard, and can be of any shape – Circular, Oval, Rectangular, Square, Octagonal and can be self-supported or column supported (concrete or SS316).
  • Self-Supported Aluminum Geodesic Dome Roofs area the best choice for replacing roofs on existing ground storage concrete tanks and reservoirs. The extremely strong yet lightweight design will add minimal weight to existing foundations that may not be designed for excessive loads.
  • Protection from external elements: The dome-shape design provides excellent protection from external elements such as wind, rain, and snow, which can cause damage to the tank roof. Aluminum is a strong and durable material that can withstand harsh weather conditions, making it an ideal material for the construction of geodesic domes
  • The prefabricated aluminum domes are a cost-effective option as they can be easily installed over existing tanks, reducing the need for expensive construction. They can be built on the ground and lifted into place or built directly on the existing floating roof and winched into place. Their rapid field installation means minimum downtime at the job site.
  • Cutting edge technology controls odors in industrial environments such as Wastewater Management, Biogas Energy Recovery, and Petroleum Plants.
  • Superior in preventing evaporation and increasing conservation of potable water.
  • PE stamps are available in all 50-states.
