Inventory and value added processing is facilitated in over 1.2 million square feet of efficient, state-of-the-art facilities. CTI houses over 30,000 line items of inventory from the world’s premier manufacturers.

Chicago Tube has been very responsive in providing guidance and samples for Sico’s changeover to HSLA tube steel on a significant product redesign project. Timely delivery of short-run samples was critical to helping us verify our designs and ensure that it could be processed through our facility with existing tooling.
