  • Eliminates Ponding
  • Easy to Install
  • Long Lasting
  • Low Maintenance

Complies with bucking requirements
CST’s advanced OptiDome design complies with torsional buckling requirements which have been adopted by Eurocode, 2010 Aluminum Design Manual and International Building Code 2012.  The Double Web I-Beam, combined with aluminum’s excellent strength-to-weight ratio, provides reliable performance under the most stringent environmental conditions including heavy snow loads and high wind speeds.

OptiDome is designed to meet the latest design codes including Eurocode, Aluminum Association’s 2010 Aluminum Design Manual, IBC 2012, AWWA D108 and API 650G.

Custom Designed for you
Every CST aluminum cover is custom designed to meet the specific requirements of each project and be engineered for any snow, wind or suspended load capacity, as well as span-to-rise-ratio.  With the ability to cover spans of 1,000 feet or more, OptiDome offers a wide range of applications without unsightly beams, girders or columns.

Superior material
The unique properties of OptiDome make it far superior to other materials and alloys used for covers due to its:

  • Corrosion Resistance
  • Low Lifetime Maintenance Cost
  • Clear-Span Capability
  • Fast & Low-Cost Construction
  • Design Flexibility
  • Aluminum is a “Green Material”


Superior batten seal technology
At the core of OptiDome is its superior batten seal technology. This system increases water shedding and eliminates ponding, even on a low profile design, while providing a water-tight cover solution.  Featuring an enclosed gasket design, the batten protects against ultra-violet exposure and sealant degradation. Since battens are flush with dome panels, it eliminates ponding. They are easy to install and require less sealant than typical geodesic domes.

Economic advantages and sleek appearance
CST has combined proven dome design with modern engineering and materials to produce the flush batten aluminum geodesic dome design which offers significant economic advantages.  In addition to the optimized design and superior seal technology, the OptiDome has a smooth, sleek appearance. CST is the only dome manufacturer that offers a design with no external sealant required at the nodes.
