ATECO  specializes in the design, manufacturing, supply and installing of above ground storage tank equıpment. The management of ATECO has an extensive track record in this industry, therefore we are the experts in servicing your requirements in this area.

Aluminum Geodesic Domes

Geodesic aluminum domes are the preferred cover solution for any storage application. Aluminum dome structures are superior to other cover designs due to alternate materials due to:

Corrosion Resistance

Aluminum is inherently more corrosion resistant than other alloys. It will last the lifetime of the structure and will not be painted or repainted for protection from the atmosphere

Low Lifetime Maintenance Cost

With no corrosion or the need to repaint the structure over time, there is little-to-no maintenance costs associated with an aluminum dome

Clear-Span Capability

Aluminum’s lightweight characteristics allow for larger clear-span cover capability than structures for steel, concrete and other materials

Fast and Low Cost Construction

Creative design and lightweight components provide for installation in a third of the time it takes to install other cover systems. Less time, labor and equipment needs combine for a low total cost of installation

Design Flexibility

Aluminum’s excellent strength-to-weight ratio and creative component designs yield covers and structures that can not be achieved with other materials

The dome’s superior structural design gives it many advantages. In addition, it is important to note that the exact geometry of the dome geometry system is the same as that of the dome geometry.

ATECO Tank domes have been designed for snow loads up to 165 pounds per square foot and wind loads up to 150 mph. Our unique panel design is specifically engineered to support loads up to 500 pounds on any one square foot. We have the ability to design domes up to 500 feet in diameter.

ATECO Tank History

ATECO Tank is a worldwide company in designing, manufacturing and constructing custom aluminum covers and structures for architectural, environmental and industrial applications.[/vc_column_text][/single_tab][single_tab title=”KEY BENEFITS” tab_id=”118646d3-257c-0″]

Key Benefits

 ATECO Geodesic Dome’s advanced design and manufacturing technology provides excellent benefits. Here’s how:

  • Most effective leak-protection solution – Engineered for maximum weather-tightness for both new tanks and retrofits. ATECO provides double sealing on clamp bars to get the most effective leak protection.
  • Low maintenance cost – Aluminum alloys are corrosion resistant and do not require painting like steel fixed roofs. There’s also no need for rebolting as the connections are made by lock bolts.
  • 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 percent. By using ATECO, you can control and reused.
  • In- service  installation – Can be erected on the ground beside the tank or on an EFR and lifted into place easily. There is no need to work so installation risks are minimized.
  • Custom engineered- To accommodate a wide range of spans and loading conditions for your operation.
  • Compiling with the codes- ATECO geodesic dome roofs are being designed as per the latest edition of API 650.
  • Platforms available- We offer you centralized and gauging platforms with handrails for any kind of operation.

ATECO confirms suitability of the dome design for the service conditions, and media to be stored. Water tightness should also be observed as a design objective, where it can be tested with a water spray test or during adverse weather conditions.


The use of any material in the dome structure is either aluminum or stainless steel is expressly forbidden. Cadmium plated bolts, galvanized bolts, or other dissimilar materials can bring serious concerns for galvanic corrosion, and such cannot be used.


The use of mastic bathtub gaskets, or rubber batten bar gaskets such as Neoprene, EPDM, Viton or other rubbers is not allowed to avoid accelerated aging of the dome structure.
