Sheet Metal Fabrication
Built Here.
Not Ordered.
Most HVAC contractors subcontract their sheet metal work. Precision Mechanical fabricates in-house · custom ductwork, specialty fittings, and transitions built to spec in our Parma shop. It’s an in-house capability for the projects we install · not a fab shop for hire · and it means tighter tolerances, faster schedules, and no subcontractor markup on every job we touch.
Why In-House Fabrication Is a Real Advantage
When ductwork is subcontracted, every non-standard fitting adds lead time, every field condition requires a change order, and every custom piece costs a markup the customer absorbs. The schedule is held hostage to a vendor who doesn’t know your project.
When fabrication is in-house, a custom transition designed at 2 PM is in the shop by 3 PM and on the truck by morning. A field measurement that reveals an unexpected condition gets resolved the same day · not in a week when the revised catalog piece arrives.
This isn’t a minor operational detail · it’s the difference between a project that runs on schedule and one that doesn’t. Projects like the 14th-floor Ritz Carlton rooftop replacement require exactly this kind of fabrication responsiveness when conditions in the field don’t match the drawings.

The In-House Difference
No Lead Times
Ductwork fabricated in our Parma shop · no vendor queue, no shipping delays.
Tighter Tolerances
Built to exact spec for your installation, not adapted from a standard catalog item.
Same-Day Modifications
Field conditions change. Our shop can turn a modification the same day it's needed.
No Subcontractor Markup
In-house fabrication means no third-party margin added to your ductwork cost.
Ritz Carlton · 14th Floor
Rooftop mechanical replacement on an occupied high-rise luxury hotel. Custom ductwork fabricated in-house and coordinated with crane scheduling · no catalog delays, no schedule slippage from a subcontractor.
Multi-Location Commercial
Multi-location HVAC installations · like our Cinemark Theaters work across Northeast Ohio · require consistent, repeatable ductwork configurations. In-house fabrication delivers that consistency without per-location catalog variation.
Precision Environments
For precision temperature and humidity systems, ductwork tolerances directly affect system performance. Catalog adaptations don’t cut it · exact fabrication does.
Frequently Asked Questions
Do you fabricate commercial ductwork in-house?
Yes. We operate an in-house sheet metal fabrication shop at our Parma facility. Custom ductwork, transitions, and specialty fittings are built to specification · not ordered from a catalog and adapted on-site.
What types of ductwork do you fabricate?
We fabricate rectangular, round, and oval duct systems, including custom transitions, tees, reducers, elbows, plenums, and specialty fittings. We also fabricate stainless steel ductwork for commercial kitchen exhaust systems.
How does in-house fabrication affect project timelines?
Significantly. When ductwork is fabricated on-site, there are no vendor lead times, no shipping delays, and no waiting on catalog items that don't quite fit. Field modifications can be turned around the same day. Most projects move faster when fabrication is in-house.
Is sheet metal fabrication a service you sell on its own?
No. Our sheet metal shop runs for our own commercial HVAC installation and service projects · it's the in-house capability that lets us hit exact tolerances and tight schedules on the work we install. It isn't a retail fab shop for other contractors. The advantage goes to the client whose system we're building: no subcontractor lead times, custom-fit ductwork, and same-day field modifications.
