MFS MESA FAB SHOP PUEBLO, COLORADO
Home / About

A four-decade
steel shop on the
edge of the plains.

Family-owned, family-run. We’ve been fabricating and erecting steel in Southeastern Colorado since 1985 — through three recessions, two construction booms, and one full overhaul of the AISC standard.

Our story

It started in
a garage.

Tom Guardamondo started Mesa Fab in 1985, welding handrail in his dad’s garage in Pueblo. Forty years later it’s still a family shop.

We work on jobs that range from a single mezzanine through full thousand-ton commercial frames. The estimating team prices them all the same way: tight, fair, and exactly what it’ll cost.

Architects and general contractors hire us because we don’t pass the buck. Our drawings, our shop, our crews, our erection. If a beam is wrong, there’s one phone number to call and one answer at the other end of it.

That accountability is the whole pitch. The rest — AISC certification, on-time delivery, competitive pricing — is just the cost of being honest about the first part.

How we operate

Three goals.
Same as 1985.

We pulled these off the wall of the original shop. They’ve aged well.

01 / Goal
Quality workmanship at competitive rates.
Not the cheapest bid. Not the most expensive. The one that holds the budget and lands the job on the truck on the day you needed it.
02 / Goal
Continue excelling in fabrication and erection.
We never stopped investing in shop equipment, welder qualifications, and crew training. The trade keeps moving — so do we.
03 / Goal
Earn a respected reputation beyond Southeastern Colorado.
We’re a regional shop on purpose, but our work shows up across Colorado and into New Mexico. Quality travels.
