Tri Star Design and Manufacturing, Inc was founded in August of 1991 as an Arizona corporation. It is privately owned and operated (by Rick & Terri Lorenzen).

We operate differently than most engineering companies. We travel to your location to review the problem and brainstorm on your unique project. We get any site information we may require, whether it is drawings, field measurements or photos. We then put together a concept drawing which graphically describes our ideas and solution. We finally review our ideas with you for additional inputs or preferences and provide a detailed written quotation for your consideration. We generally do all this at no initial charge.

Our expertise generally covers the following areas:

  • Babbitt Bearing Repair
  • Engineering & Drafting Services
  • Structural and Mechanical Fabrications
  • Machine Shop Services, Including Water-Jet Cutting
  • Chute Linings AR500 & Castings (Design & Supply)
