How it goes

Drawing to standing steel,
five clean steps.

Estimating and project-management teams handle jobs from 10 to 1,000+ tons. Same workflow either way — the math just gets bigger.

01 — Intake
Drawings & Estimate
Send contract or shop drawings. Estimating returns a tight, itemized number.
02 — Detail
Approval Drawings
Our AISC-certified detailing partners produce shop drawings and return them electronically — turnaround in 5 to 10 business days.
03 — Build
Fabrication
Cut, fit, weld, finish, paint. AISC-certified workflow with traceable material.
04 — Deliver
Load & Ship
Bundled and trucked on a schedule that matches your erection sequence.
05 — Erect
Field Erection
Our crews stand the steel. Same shop, same accountability, signed off at handover.
Common questions

A few things
GCs usually ask first.

The answers to the calls we take ten times a week. If yours isn’t here, send drawings — we’ll answer the rest.

How fast can you turn around a bid?

Usually within a week of receiving drawings. Complex jobs — heavy structural with a lot of misc, AESS scope, or unusual stainless — can run longer. We’ll tell you up front when we open the file.

Do you fabricate, erect, or both?

Both. We fabricate in our Pueblo shop and erect with our own crews. One company end-to-end, one phone number when something needs to change.

What kind of steel do you handle?

Heavy structural steel and miscellaneous metal fabrication. Columns, beams, trusses, bracing, base plates, gussets — alongside stairs, railings, embeds, canopies, screen walls, and the hundred small pieces that go on the same job.

Where do you work?

Headquartered in Pueblo, Colorado. We fabricate here and ship nationally. Our erection crews run regional jobs out of Pueblo and travel when the project calls for it.

Are you AISC certified?

Yes. We’re a Certified Structural Steel Fabricator under the American Institute of Steel Construction program, re-audited annually by a third party. Welder qualifications maintained current under AWS D1.1 and D1.6.
