Sheet Metal Fabricator

Before ductwork ever gets installed, it has to be built, and that starts with you. This page walks you through the real path, from your first day to the income that comes with experience.

The Path

Building ductwork that fits perfectly takes real skill. Here's how that skill typically develops, stage by stage.

Apprentice (Year 1-4)

Journeyman Fabricator

Lead Fabricator/Shop Supervisor

You start by learning to read shop drawings and operate cutting and forming equipment under a licensed fabricator, often through a formal apprenticeship. Wages typically start around 40 to 50 percent of full journeyworker pay, then step up as your skills develop. Source: U.S. Department of Labor.

You're building ductwork and custom metal components independently, reading specs and producing exact fits the first time. Median annual wage: $61,800. Source: U.S. Bureau of Labor Statistics, May 2025.

Years of precision work can lead into running a fabrication shop, training apprentices, or specializing in architectural metalwork. Top 10 percent of earners make more than $105,650 a year. Source: U.S. Bureau of Labor Statistics, May 2025.

The Real Timeline

The Real Work

What You'll Actually Do

Ductwork doesn't fabricate itself, and precision here determines how well every system downstream actually performs.

  • Read shop drawings to determine exact duct dimensions, transitions, and fitting requirements

  • Cut and form sheet metal using a brake, shear, and plasma cutter to fabricate custom ductwork

  • Weld and seam duct sections so they hold pressure without leaking air along the way

  • Fabricate custom transitions and offsets for jobs where standard fittings simply won't fit

  • Coordinate with installers on delivery timing so ductwork arrives exactly when a job needs it

  • Inspect finished pieces against the original spec before they ever leave the shop

Know Yourself

Are You a Fit for This Role?

Building the ductwork a whole system depends on rewards precision most trades never demand this directly.

  • Mathematically precise, a fraction of an inch off throws off an entire fitting

  • Mechanically minded, reading a shop drawing and picturing the finished piece in three dimensions

  • Physically capable, sheet metal is heavy and the shop floor stays on its feet all day

  • Patient with repetitive, exacting fabrication work done the same careful way each time

  • Comfortable operating brakes, shears, and welding equipment safely and confidently

  • Takes real pride in a finished piece that fits perfectly the first time it's installed

A Real Workday

A Day in the Life

What does sheet metal fabrication actually look like day to day? Here's a real look.

A stack of shop drawings waits at your station first thing, today's job calling for a run of custom transitions that won't come out of a standard supply catalog. You measure and mark the sheet metal before running it through the brake, forming clean bends that'll match the exact angles the job site needs. Does sheet metal work require welding certification? Depends on the shop and the job, some fabrication runs entirely on seaming and riveting, while pressure-rated commercial ductwork often does call for certified welds. Midday brings a rework request, an installer called in with a duct run that needs a last-minute dimension change, and you fabricate the new piece fast enough that it doesn't hold up tomorrow's install schedule. By afternoon, you're inspecting a finished batch against the original spec, checking every seam before it leaves the shop for a job site. Some days run on repeat, familiar fittings at steady volume. Others demand a genuinely custom piece nobody's built before. Either way, the ductwork leaving your shop today becomes the backbone of a system somebody's going to depend on for years.

The Real Cost

What It Actually Costs to Start

Not free, but no years of tuition either.

Basic Hand Tools

Boots & Safety Gear

Apprenticeship Enrollment

Few hundred dollars to start, employer provides the larger fabrication equipment.

$100-$200, steel-toe boots, safety glasses, and gloves are a real upfront cost most people do not budget for.

Typically free, most sheet metal apprenticeships are paid, not tuition-based.

Common Questions

FAQ

Is this the same as being an HVAC installer?

Do I need welding experience?

Not always to start, but it is a valuable skill to build in this role.

No, fabricators build the ductwork in a shop, installers put it in on-site.

Is this mostly shop work or job site work?

Can this lead into other roles?

Yes, experienced fabricators often move into shop supervision or estimating.

Mostly shop-based, though some fabricators do on-site custom work.
