About BlackLine Metalworks
BlackLine Metalworks was built on the belief that steelwork should do more than perform — it should reflect precision, intention, and long-term reliability.
Founder Donte Singleton is a professionally trained metal fabricator whose background is rooted in hands-on craftsmanship, practical problem solving, and years of fabrication experience across residential and commercial environments. After relocating to South Dakota and completing formal welding training, he launched BlackLine Metalworks with a simple focus: build it right, communicate clearly, and never cut corners.
Today, BlackLine Metalworks serves builders, designers, and property owners who value clean execution, dependable timelines, and steelwork that integrates naturally into the finished space.
From architectural rail systems and stairs to gates, fixtures, and specialty fabrication, every project is approached with direct oversight, disciplined craftsmanship, and a commitment to work that lasts.
No shortcuts. No guesswork. Just steel built with purpose.
