Metal Building Company Janesville WI | Manufacturing & Installation
Janesville needs reliable buildings. Foremost Buildings has been providing them for over three decades. We make buildings at our Wisconsin facility and install them on your site. No middlemen. No outsourcing. Just American steel and experienced crews.
Your Janesville project gets commercial steel buildings for business use, industrial metal buildings for heavy operations, or agricultural metal buildings for Rock County farms. We handle everything from initial design through final construction.
Services for Janesville Projects
Finding a company that makes buildings is easy. Finding one that also installs them? Harder. We do both because we own the shop and employ the crews.
Engineering Your Building
Our engineers design custom metal buildings meeting Janesville codes and Wisconsin weather. Try our 3D metal building design tool yourself, or work with our team on complex projects.
Southern Wisconsin gets serious snow. Wind matters. Temperature swings matter. We design for real conditions, not textbook standards.
Building Components
We manufacture pre-engineered metal building systems using American steel. Frames get welded. Panels get formed. Roofing gets assembled. Everything matches your specifications.
Running late on your timeline? We add production shifts. That’s possible when you control the manufacturing.
Installation Services
Most companies ship parts and disappear. Not us. Our erection services bring crews to your Janesville site who’ve installed these buildings countless times.
Quick work. Done correctly. People who work for us, not subcontractors we can’t control. You can also buy materials only if you prefer your own installation.

What Buildings Cost
People ask about steel building costs regularly. Fair question. Size affects price. Features affect price. Installation choice affects price.
We quote materials only or complete installation. You pick what fits your budget.
Metal Building Benefits:
- Cost less than conventional construction
- Build faster with our installation
- One company handles everything
- Low maintenance needs
- Energy efficient insulation
- Long lifespan
