Aluminum Domes
Looking for a Geodesic Dome Roof?
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, bulk material storage facilities and architectural structures.
CST’s aluminum dome structures are ideal for the following applications:
Potable Water
Aluminum domes are the preferred cover for potable water storage tanks. Whether it is an above ground elevated water storage application, 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 the corrosion resistant properties of aluminum domes which makes it ideal for tough outdoor environmental challenges.
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 make sit the ideal material for corrosive wastewater applications. Lightweight dome structures are easy and fast to install reducing downtime in municipal and industrial treatment operations.
Architectural Structures
Aluminum domes are utilized in many different and varied architectural applications. The unique ability of aluminum to weather tough environmental conditions makes it a strong choice of architects and engineers for covers and structures for theaters, gymnasiums, atriums, vaults and custom building envelop shapes and geometric designs.
Architecture
CST is the world’s largest manufacturer of factory-coated storage tanks and clear-span aluminum domes and covers for municipal and industrial water and wastewater applications.
Water & Wastewater Tanks and Domes
Wastewater applications demand rigorous tank performance that also complies with strict environmental standards and regulations. CST provides a complete line of integrated storage solutions that offer worry-free, long-lasting and high-quality results. CST tanks and domes are corrosion resistant with low lifetime maintenance cost. All our wastewater products are manufactured in ISO 9001:2015 Certified facilities under the closest production controls.
CST is home to world-class brands including AQUASTORE®, TecTank™ (formerly Columbian Steel Tank Company, Peabody TecTank and Columbian TecTank®) and OptiDome®. To date over 375,000 tanks and 20,000 covers have been installed in more than 125 countries around the world.
CST’s water storage tanks are the preferred storage tanks for potable water storage and are available in bolted and welded designs, capacities of 4,000 to more than 6 million gallons and in-ground, standpipe or elevated configurations.
AQUASTORE glass-fused-to-steel tanks are the premium technology in the tank market. AQUASTORE tank owners choose glass-fused-to-steel technology over other tank designs for several reasons.
CST designs innovative clear-span aluminum covers for wastewater process and water storage tanks that help control odorous emissions and prevent water intrusion. CST’s aluminum domes and flat panel covers provide the strength, durability, odor control and protection characteristics unavailable in steel, plastic, fabric or any other materials of construction.
Water, wastewater plants and storage facilities are increasingly turning to the CST Aluminum Advantage. In addition to low maintenance, low cost and low profile advantages, CST aluminum domes and reservoir covers are versatile enough to permit a wide range of accessories important to the water, reservoir and wastewater industry. Using proprietary design software CST’s aluminum domes and tank covers are noted for their ability to meet exacting live load requirements by providing greater stiffness and strength, pound-for-pound, than any other dome geometry system.
CST is unmatched in providing solutions to these production facilities:
Aeration
Anaerobic & Aerobic Digestions
Disinfection
Clarifier
Influent or Effluent Flow Equalization
Frac Water
Landfill Leachate
Primary & Secondary Sedimentation
Sequencing Bat Reactors (SBR)
Sludge Storage
Storm Water Run-off
Trickling Filters
Reservoir Cover Solutions
CST has been providing custom engineered all-aluminum water reservoir cover solutions in the potable water market for more than 55 years. Large water basins and reservoirs are a particularly difficult challenge. The water must be covered effectively to meet surface water regulations. At CST, our aluminum specialty covers have been designed to cover some of the largest water reservoirs in the world.
CST has a unique “strut and panel” system that can accommodate virtually any reservoir shape or size. The all-aluminum design employs geodesic dome engineering principles for a lightweight cover as clear-span, truss supported, or internally supported by columns.
New or Retrofit
CST’s cover systems are ideal for both new construction or retrofit projects and require little modification of the existing tank.
Perhaps most importantly, CST all-aluminum covers are inherently corrosion resistant and offer strength and durability unmatched by steel, wood, concrete, plastic or other alternatives. CST aluminum cover systems provide maintenance-free, long-lasting (minimum 50-year design life), secure, and environmentally friendly fixed cover solutions to protect valuable potable water.
