STI Group holds several nationally-recognized certifications that qualify us for the most complex and large-scale project demands in our industry. Attaining these certifications was an important part of STI Group’s goal to be a single-source contractor for projects. We want to meet our client’s fabrication and construction needs under one contract. These certifications allow us to also show our clients that we meet and exceed the national standard for quality, providing superior deliverables for every project.
