Pittsburgh Tank Corporation is a leader in the bulk storage industry. Our dedication to engineering excellence and quality workmanship is only part of the reason why Pittsburgh Tank rises above the rest. We recognize that a silo is part of a complex, interdependent system. To provide complete customer satisfaction we first strive to truly understand exactly what each and every customer's precise bulk storage requirements are and how we can deliver a system on time that provides effective, efficient, affordable and durable service that can truly rise above the rest.


Each storage application is unique and requires a system designed in accordance with the customer's specifications. You'll find our silo skirt, legs, or gusset supported in configurations up to 16 ft. in diameter and heights over 100 ft.

Gravity Tube Blenders

Each gravity tube blender is a vertical mixing chamber that can double as a storage silo. Through the use of staggered tubes, stored material is recirculated quickly and efficiently. The end result is a uniform blend with reliable consistency.


With optional single, multiple, or chisel cones, divided wall, level sensors, access doors, straight or spiral stairs, ladders, walkways, and/or platforms, if you can think it, we can build it!

All silos and tube type blenders are one-piece construction, available in carbon steel, stainless steel or aluminum, thus minimizing field assembly and installation time.
