The manufacturing of interstate highway guide and regulatory warning signs requires expert level abilities and equipment to weld, saw, shear and punch metal. Interstate SignWays has the facility and expertise to produce any sign type using all necessary techniques. Green aluminum extruded and flat panel interstate highway guide signs vary in size and specification based on the state. A state DOT sign in Florida is not the same as the sign in Texas. Many factors in these differences include weather, geography, budget and historical influence. Due to the custom specifications and size of large overhead guide signs, they remain very much a handmade manufacturing process.
We have been purchasing signs from Interstate SignWays for over 20 years. The knowledge of their staff, the quality of their work and their service is exceptional. We look forward to working with them for many more years. Dan Williams, Vice-President Safety Contractors, Inc.
