The Shop That Says Yes
Since 1970, Finnco Fabricating has operated from the same corner of Milwaukee’s Harbor District, rolling, bending, and forming metal for the manufacturers who build America’s equipment.
The company was founded on a simple premise: there are jobs that need a specialist. Not a general fabrication shop that happens to own a plate roll. Not a massive service center that won’t take orders under 1,000 pieces. A dedicated forming shop with the equipment, the experience, and the willingness to take on parts that are too thick, too hard, too tight, or too complex for anyone else.
Fifty years later, that premise hasn’t changed. What has changed is the depth of capability behind it.
What Finnco Is, And What It Isn’t
Finnco is a metal rolling and forming specialist. The shop doesn’t chase every category of metalwork. There’s no laser. No paint booth. No CNC machining center. What there is: seven plate rolls covering gauge material to 3-inch plate, two heavy press brakes up to 750 tons, three angle rolling machines, tube bending capability, shearing, punching, and the welding stations needed to complete the parts that come off those machines.
This focus is deliberate. A shop that does one thing for 50 years does it differently than a shop that added the capability last quarter. The operators know how AR400 behaves when it hits the rolls. They know which die to pull for a multi-hit part on 1-inch T-1. They know that a cone with progressive radii requires a different setup than a standard cylinder, and they’ve done thousands of both.
That institutional knowledge is Finnco’s actual product. The machines are the tools. The experience is the differentiator.
The Work
Every week, roughly 30 jobs move through Finnco’s floor. Part counts range from 1 to 500. Some parts are small — 16-gauge × 10″ × 1″. Some are large — 1-inch plate × 50 feet × 10 feet. Some are single-operation: one bend in the press brake, or rolled to a single radius. Others require multiple operations — pre-formed on the brake, rolled to progressive radii, then welded complete.
The customer base spans more than 150 companies per year, concentrated in the Upper Midwest: Wisconsin, Illinois, Iowa, and Minnesota. Industries include construction, agriculture, mining, heavy equipment, on-road transportation, and military/defense. Many of these are long-term relationships built on a pattern that repeats itself: a buyer sends a difficult RFQ, gets a fast response, receives the part on time and to spec, and doesn’t have a reason to look anywhere else next time.
Finnco has never collected formal testimonials. The stream of returning customers and referrals speaks for itself.
The Location
Finnco has always been in Milwaukee’s Harbor District, on the south side of the city. The Harbor District is part of Milwaukee’s industrial DNA — a neighborhood of manufacturers, fabricators, and trades companies that have powered the region’s economy for over a century. Proximity to I-94, I-43, and the Port of Milwaukee provides efficient freight access across the Midwest and beyond.
The facility isn’t a showroom. It’s a working shop, organized around the flow of material from receiving to shipping: shear to size, punch if needed, form or roll, weld if required, load for pickup or delivery. The layout reflects the same philosophy as the business itself — purpose-built, no wasted motion, every piece of equipment earning its floor space.
The Approach
Quoting: Same-day or next-day. Finnco estimates from customer drawings and provides clear pricing with realistic timelines. No RFQ disappears into a queue.
Turnaround: 5 to 10 business days from receipt of material for most jobs. The team communicates proactively on delivery expectations — if something changes, the customer knows before they have to ask.
Prototyping: Yes. Finnco regularly works with customers prototyping new parts. Proving out a design before committing to production is part of the service.
Material: Finnco works with customer-supplied metal or can source material directly. A36, stainless steel, Grade 50, AR400, AR500, T-1, and specialty alloys are all within the working range.
The Commitment
Finnco doesn’t pretend to be the biggest shop. It doesn’t try to be everything to everyone. What it does — rolling, forming, bending, shearing, punching, and welding — it does with the depth of capability, the speed of response, and the reliability that come from five decades of deliberate specialization.
When the job matters and failure is not an option, Finnco is the shop that gets it done.
