Your Trusted Local Metal Fabricators in Rapid City
At Twisted Tin Flow Solutions, we’re more than just a gutter and metal fabrication shop—we’re a family-owned business built on hard work, experience, and pride in doing things the right way. With over 30 years of hands-on HVAC and metal fabrication experience, our foundation comes from real-world knowledge, not guesswork. We understand how things are built, how they perform, and what it takes to get the job done right the first time. We started Twisted Tin with a simple goal: to provide reliable, high-quality metal solutions that contractors and homeowners can count on.
Built on Integrity


Our Commitment
We understand the field because we’ve worked in it - We communicate clearly and show up when we say we will - We take pride in craftsmanship—because our name is on everything we build. At the end of the day, we do this because we love it. If it’s metal, there’s a good chance we can build it—and build it right.


Your Dedicated Experts
Desi and Steve Van Dam are the husband-and-wife team behind Twisted Tin Flow Solutions—a business built on hard work, real-world experience, and a shared commitment to doing things the right way.
Steve brings decades of hands-on experience in HVAC, metal fabrication, and exterior construction, with a reputation for keeping projects moving efficiently while maintaining high-quality standards. His approach is simple: clear communication, strong systems, and never cutting corners.
Desi leads the operational and financial side of the business, combining organization, adaptability, and a strong work ethic to keep everything running smoothly behind the scenes. Her focus on communication and follow-through ensures customers and partners feel supported every step of the way.
Together, they’ve built their careers in the Black Hills, raising a family and creating a business rooted in trust, reliability, and craftsmanship. Outside of work, you’ll often find them enjoying the outdoors—riding motorcycles, camping, or spending time with their kids and grandkids.
At their core, Desi and Steve believe that good business is built on relationships. Whether it’s custom metal fabrication, seamless gutters, or supporting other contractors, their goal is always the same: deliver quality work, stand behind it, and treat people right.



Quality You Can Trust


Lasting Solutions
As a family-owned business, this isn’t just a job—it’s personal. Every piece of metal that leaves our shop reflects our name and our standards. What drives us is the work itself. We enjoy building, problem-solving, and creating something that lasts. If it’s metal, we take pride in making it right.
