About Tri-State Industries

Our history

As the steel manufacturing industry became increasingly competitive, we had to examine all our capabilities to maintain high levels of productivity. With welding being a substantial part of the business, TSI began streamlining those projects by using advanced technology so processes could occur simultaneously. By automating our services as much as possible, we maximized productivity, increased accuracy and reduced costs.

TSI today

TSI continues to evolve, as the lessons we’ve learned have led us to understand the best combinations of technology and manufacturing that deliver quality products. TSI’s experience can serve your business by optimizing your processes so you can refocus on core competencies. In today’s markets, the most successful companies outsource inefficient processes that strain internal resources.

Our locations in Hammond, IN, with over 80,000 sq. ft. of manufacturing space, and Alexandria, LA, with 65,000 sq. ft. of fabricating and welding space, can meet all your needs. We operate under compliance to ISO9001:2008 Standard.
