Tri-State/Service Group produces shop-fabricated metals in compliance with ANSI/SPRI ES-1. We have always followed the specification details outlined in the Architectural Sheet Metal Manual published by SMACNA (Sheet Metal and Air Conditioning Contractors’ National Association). In fact, our former CEO and Chairman was one of a handful of select contributors to this text. The industry regards the Architectural Sheet Metal Manual as the authority on all types of architectural sheet metal details. Additionally, our edge metals comply with the NRCA 5th Edition Construction, Fabrication and Installation Details. Both SMACNA and NRCA details have passed ANSI/SPRI ES-1 testing. The Tri-State/Service Group also complies with all appropriate manufacturers’ details.


We can field measure, custom fabricate, and install architectural metal, achieving a superior fit to pre-fabricated metals. A successful finished job absolutely depends on the quality of the field installation. We control the schedule and time of completion, usually resulting in better, faster service. We have the ability to adapt to job site changes, tweak details and handle last-minute changes by the owner, architect, or others–while maintaining a quality, watertight installation. In short, we are the experienced and knowledgeable choice for architectural metal and its effective installation.
