Sheet Metal & Custom Fabrication
Commercial Sheet Metal Fabrication Built for Real-World HVAC/R Work
Rainy River Refrigeration & Mechanical provides in-house sheet metal fabrication to support commercial and industrial HVAC/R projects. From ductwork to brackets and specialty components, everything is built to match real field conditions — ensuring proper fit, clean installation, and long-term system performance.
Our fabrication is driven by hands-on experience in the field, allowing us to build practical solutions that install correctly and perform the way they should.
Ductwork Fabrication
We fabricate ductwork specifically for the job — not from stock sizes that don’t quite fit.
- Supply and return duct systems
- Transitions, offsets, and takeoffs
- Duct modifications and resizing
- Replacement of damaged or undersized duct
Built for proper airflow, clean fitment, and reliable performance.
Custom Metal Components
We build the pieces that make HVAC/R systems come together in the field.
- Equipment brackets and mounting supports
- Plenums and simple housings
- Covers, caps, and patch panels
- Job-specific fabricated components
Designed for durability, accessibility, and real-world service conditions.
Ventilation & Exhaust
Fabrication support for ventilation systems and air movement upgrades.
- Exhaust duct and fittings
- Makeup air modifications
- Mechanical room ventilation
- General ventilation improvements
Focused on practical, code-conscious installations that perfor
Retrofit & Repair Work
Existing buildings rarely allow for standard solutions — we fabricate to solve that.
- Duct corrections and reconfiguration
- Airflow and static pressure improvements
- Repair or replacement of failing components
- Modifications to support new equipment
Built with a service-first approach to improve system performance and reliability.
