"Why is sheet metal work important on data centers?"

"Even with the move to liquid cooling, large air-side systems remain. Air handlers, supply and return plenums, exhaust ductwork, and rooftop curbs are all sheet metal scope, often at sizes that dwarf typical commercial work."

"What does a sheet metal worker do on a data center?"

"Fabricate and install large-diameter rectangular and round duct, plenums, exhaust systems, and architectural panels. The work pairs shop fabrication with field installation and rigging."

"How do I become a sheet metal worker?"

"Train through a registered apprenticeship, often via SMART (Sheet Metal, Air, Rail and Transportation Workers) locals, or a trade school HVAC sheet metal program. Apprenticeships run 4 to 5 years and pay throughout."

"Is sheet metal work tied to liquid cooling?"

"Less directly than pipefitting, but air-side systems still handle ventilation, makeup air, and exhaust. Even fully liquid-cooled rooms need conditioned air for personnel and adjacent spaces."

Sheet Metal Workers and Data Center Ductwork (2026)

Updated June 8, 2026 | TradeCareerPath Editorial Team

Sheet metal workers tend to get less attention in data center coverage than electricians and pipefitters, but the air side of a hyperscale building is still a major scope. Large air handlers, plenums, exhaust ductwork, and architectural metal all flow through sheet metal shops and field crews.

What the Scope Looks Like

Large-diameter rectangular and round ductwork for supply, return, and exhaust
Plenums for air handler discharge and return
Rooftop curbs and equipment supports
Smoke evacuation and fire-rated ducts
Architectural and ornamental metal panels in some designs

The duct sizes on hyperscale jobs commonly run 60 inches and larger, which puts pressure on shop fabrication capacity and field rigging.

Why the AI Buildout Helps Sheet Metal Workers

Two effects. First, even fully liquid-cooled racks still require conditioned ventilation for personnel and adjacent spaces. Second, the building shells are larger, which means longer duct runs and more rooftop equipment. The shift in cooling philosophy has not eliminated the air side; it has just changed the mix.

For workers, that translates into steady demand wherever new campuses are breaking ground.

A Day in Data Center Sheet Metal Work

Shop fabricators run brakes, plasma tables, and seam machines through the morning. Production runs of large-diameter rectangular and round duct stage out for delivery. In the field, crews rig and install sections overhead with picker support. Installers connect plenums to air handlers, set rooftop curbs, and tie into exhaust systems. Insulation and sealing follow.

Hyperscale duct sizes commonly run 60 inches and larger, which puts pressure on shop capacity and field rigging skill.

Career Progression and Pay Drivers

Stage	Years	What changes
Apprentice (1st year)	0-1	Shop helper, basic layout
Apprentice (mid-late)	1-4	CAD layout, rigging, install assist
Journeyman	4-5	Full shop or field role
Specialty journeyman / fabrication lead	5-10	Complex layout, lead fabrication, install foreman
Foreman / superintendent	10+	Crew leadership

Pay drivers:

CAD and layout. Layout-strong fabricators move into specialty roles fast.
Welding endorsements. Some sheet metal scope crosses into welding work.
Rigging skill. Field crews who can rig large-diameter duct efficiently are kept busy.

How to Get Started

Apply to a registered sheet metal apprenticeship through a SMART local, or enroll in a trade school sheet metal or HVAC program.
Build shop fabrication and CAD layout fundamentals.
Earn OSHA 30 and any rigging credentials your contractors require.
Target mechanical contractors with mission-critical work in your region.

BLS National Snapshot for Sheet Metal Workers

Metric	Value	Source
Median annual wage (2024)	$60,850	BLS OES
25th percentile	$47,290	BLS OES
75th percentile	$79,620	BLS OES
90th percentile	$102,680	BLS OES
Total U.S. employment (2024)	127,000	BLS OEP
Projected change to 2034	+2.4%	BLS OEP
Annual openings (avg)	10,600	BLS OEP

National figures are a baseline. Data center work commonly pays above the national median because of compressed schedules, higher qualification bars, and routine overtime.
