About Us

Founded in March 2024 by industry professionals, One Source Designs Inc. was established with a mission to deliver customer-centric steel solutions grounded in quality and reliability. What began as a design and drafting service has since evolved into a comprehensive provider of structural steel services, including mezzanine fabrication and installation, as well as roof open web steel joist (OWSJ) reinforcements. Proudly local, One Source Designs maintains all design and drafting operations in-house—ensuring consistent quality, seamless communication, and a deep understanding of client needs. Backed by over 30 years of combined industry experience, our team is committed to going above and beyond to meet project demands with precision and professionalism. Our core values—Customer Commitment, Integrity, Excellence, Collaboration, Local Expertise, and Adaptability—serve as the foundation of every project we undertake. With trusted partners and a growing network of engineers, we are equipped to provide engineered solutions that meet the highest standards of safety and performance.
