Who We Are

Since 1993, Assembly Systems has offered OEM assembly, subassembly, parts kitting and a full range of support services. We focused initially on the bus coach industry, but our capabilities have expanded significantly. Today, Assembly Systems offers a variety of fully managed assembly work for dozens of customers. We also have great expertise in upfitting heavy trucks with a variety of equipment, from crane assemblies to railroad packages.

We have great people. We have a great process. Over our 25 years, we have built a track record and client list that other contract assemblers envy. We are proud to offer a one-source solution to plan, build, fulfill and support products critical to growing businesses and those needing help to meet production challenges.

Interstate Assembly Systems is just one of our Interstate Companies divisions.

These divisions touch thousands of customers in many different industries. They work together, sharing training, knowledge, and resources.
