With a robust quality system, we have established and maintained accreditation to AS9100 and NADCAP regulatory standards along with multiple other customer-specific site accreditations. Our relentless pursuit for quality excellence and customer satisfaction has translated to numerous approvals for significant aerospace primes including Boeing, Northrop Grumman, Collins, and Lockheed Martin; many of these specification approvals feature a limited list of suppliers and require significant technical oversight, which STS Metals proudly possesses. With over 25+ years of quality and technical experience per site, STS Metals has the technical capacity to meet the most complex needs of the industry and ensure the delivery of a high-quality product to our customer.
