What makes us different

Typically steel fabricators land in two areas – too busy to return calls and get small jobs done or too large to care about the little jobs and residential work. We offer the flexibility of a small fabricator with the knowledge of a large fabricator coupled with unmatched customer service and response times. We have over 40 years of experience in the industry and use that experience to our clients’ advantage, aiding our clients with direction and design help as needed.

We have the capabilities to produce structural steel for small to midsized projects including stairs, rails, industrial fabrications, skids, platforms, etc. Lifting capacity is capped around 4,000lbs for any individual piece. We also have the knowledge and experience to accommodate any miscellaneous metals project including large stair cores.


SteelGen was founded in 2021 by Jamie Weiss and Don Anderson. While working together at another steel fabrication company, Jamie and Don discovered a shared passion for steel construction done the right way and wanted to break out on their own.


SteelGen is located at 10765 Turner Blvd, Longmont, CO 80504, right at the intersection of I-25 and Route 119. Our facility is 8,800 square feet with a 6,200 square foot fabrication floor and 1.4 acres of outdoor yard space to tackle both the large and small jobs.


We follow the American Institute of Steel Construction (AISC) guidelines for quality control and assurance and have an AWS certified welding inspector on staff.
