CST Leads the Way on Geodesic Domes

CST’s Optidome is a technologically advanced, sleek, flush batten aluminum dome that delivers superior stability, functionality and aesthetics.

CST is the world’s leading designer and manufacturer of innovative clear-span aluminum geodesic dome roof structures for municipal water and wastewater storage, petrochemical terminals and bulk material storage facilities.

The flush batten Optidome is a next generation aluminum geodesic dome from CST. The design features of Optidome include:

Flush batten design
Protection from UV and sealant degradation
Gasketed stainless steel fasteners
Eliminates ponding
Easy to install
Long lasting
Low maintenance
Environmentally friendly

Engineered for Performance

CST’s advanced Optidome design complies with torsional buckling requirements which have been adopted by Eurocode, Aluminum Design Manual and International Building Code. 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 Aluminum Design Manual, IBC, AWWA D108 and API 650G.

Customized for Your Project

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. CST has the ability to cover spans of 1,000 feet or more. We can design high-profile “free span” covers for most applications, as well as low-profile column-supported solutions, as needed.

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 and low-cost construction
Design flexibility
Aluminum is a “green material”

Superior Technology and Value

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.

CST has combined proven dome design with modern engineering and materials to produce the flush batten aluminum geodesic dome design offering 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.

APPLICATIONS

CST’s flush batten Optidome is ideal for the following applications:

Potable Water

Aluminum domes are the preferred cover for potable water storage tanks. They can be put on just about any type of storage tank — field-welded, bolted, concrete, etc. The aluminum dome is the most durable and lowest lifetime cost solution for thousands of water districts in North America and throughout the world. No other cover design has its corrosion resistant properties, making it ideal for tough outdoor environmental challenges.

Petroleum

Our covers help operators achieve regulatory compliance and bring new levels of cost efficiency to storage facility operations. By controlling hazardous vapor emissions and preventing water intrusion, our domes provide environmental and stored product protection and reduced lifetime maintenance and operating costs.

Wastewater

Clear-span aluminum domes provide cover to wastewater tanks while still allowing for space to accommodate process equipment underneath or on top of the dome. Aluminum’s superior corrosion resistance makes it the ideal material for corrosive wastewater applications. Lightweight dome structures are easy and fast to install, reducing downtime in municipal and industrial treatment operations.

Bulk Storage

Our aluminum domes are custom designed around a bulk storage facility’s specific clearance requirements, basin configuration and bulk handling equipment. Structurally efficient and lightweight, they maximize bulk storage capacity, minimize foundation costs and provide dependable protection from the elements while remaining virtually maintenance free.
