Sheet metal that ships inside your HVAC equipment
Commercial HVAC and refrigeration OEMs need a contract manufacturer who understands their substrate mix: lighter-gauge galvanized for plenums and ductwork, heavier cold-rolled steel for equipment cabinets, sanitary stainless for refrigeration display cases. SPM brings all of these under one roof. Our fiber laser cutting handles tight-pattern plenum perforations efficiently, our ATC press brakes form complex cabinet bends without manual setup, and our in-house powder coat applies durable finishes that handle the temperature swings and condensation common in commercial HVAC installs. Combined with our AWS D1.3 certified welding and electro-mechanical assembly, we deliver complete equipment chassis ready for HVAC OEM final assembly and ship-out.
Use Cases
What SPM builds for HVAC programs
Air Handlers
Cabinets for commercial AHUs and rooftop units
Welded sheet metal cabinets for commercial air handling units (AHUs) and rooftop equipment. Galvanized and powder-coated for outdoor durability, with access panels and gasket-sealed seams.
Plenums & Ductwork
Custom plenums and transition ductwork
Sheet metal plenums, transitions, and custom ductwork for commercial HVAC and ventilation. Tight-tolerance laser cutting for perforation patterns; welded or riveted construction per project spec.
Heavy Equipment
Chassis for chillers, boilers, and condensers
Welded structural chassis and cabinetry for chillers, boilers, and condensing units. Heavier-gauge cold-rolled steel construction with AWS D1.3 certified welds for thermal cycling durability.
Refrigeration
Display case and refrigeration sheet metal
Sanitary stainless and powder-coated sheet metal for commercial refrigeration display cases and walk-in cooler interior panels. Stainless 304 for sanitary surfaces; specialty alloys on request.
