120+ Year Legacy of Silos, Domes and Vaults

Silos and Columbian TecTankCST’s  bolted silo manufacturing dates back to its roots as Columbian Steel Tank Company™, Peabody TecTank™ and Columbian TecTank®, now CST Storage, and our dome and vault manufacturing founded by Temcor and Conservatek®, now CST Covers. Our storage solutions are custom engineered to our customer’s exact specifications, designed using state-of-the-art CAD and stress modeling tools, and then manufactured in one of our 6 ISO-Certified manufacturing facilities located in the US and Europe. Our dedicated Project Management teams ensure a smooth purchasing, manufacturing and delivery process while providing a single point of contact throughout the engineering, manufacturing and construction processes.

CST now offers TecTank FP to it's product portfolio.  The new design of TecTank FP includes an optimized bolt pattern, increased steel thickness, reduced hardware and fewer penetration points.  The new jackable flat panel bolted design of TecTank FP is superior to competitive designs in the dry bulk industry and will be available in short lead time pre-configured models and fully customizable designs.  With the addition of CST's TecTank FP, CST becomes the only tank supplier in the world to provide both a flat-panel, jack-built- tank and chime-panel (CP) scaffold built, capable of safely and economically being installed on every diverse site condition imaginable.  

Direct Flow Channel (DFC) Blending

Direct Flow Channel (DFC) blending combines the quality of CST silos with a proprietary design for gravity blending of material in the silo to minimize the effects of batch variables. Based on design parameters, analysis and field experience developed by CST’s engineers over the last four decades, we have developed a solution that will increase flow efficiencies, reduce cleanout costs and save our customers money.

Integrated Loading Platforms and Accessories 

CST’s  ability to satisfy our customer’s needs, improve construction times and save them money doesn’t stop with providing just silos, domes or vaults. We can design and manufacture silos for drive-through and train-through operation as well as integrate accessories such as walkways, level indicators, load cells units. Our partners are also capable of providing a variety of material handling solutions for loading and unloading all of our storage solutions.

FIFO and LIFO Designs 

CST can manufacture silos with standard hopper slopes for either first-in-first-out (FIFO) or last-in-last-out (LIFO) flow. Our engineering teams can also custom design silos and hoppers to meet customer’s specific flow characteristic needs.
