Structural Steel

Platforms, stairs, reinforcement, and miscellaneous metals are the backbone that carries everything else. We fabricate and install structural steel in the shop and in the field — and we can engineer and permit it when the job calls for it.

In short

We fabricate and field-install structural steel and miscellaneous metals — platforms, mezzanines, stairs, handrail and egress, equipment reinforcement, tie-ins and supports — including engineered, permitted design-build.

Structural work has to be right, code-correct, and safe to install. We shore it properly, build it to drawings, and tie it back cleanly — whether it is a new egress stair or RTU reinforcement on a roof.

When a project needs more than welding, we take it from concept through engineered shop drawings and permits to a finished, code-correct install — reporting straight to the GC.

Design-build proof

Concept to permitted install, reporting to the GC

On a roof access project we cut the penetration, designed and added RTU/roof structural reinforcement, and installed a roof access hatch with an internal ship’s ladder and external aluminum ladder.

We pulled the permits, produced engineered shop drawings through our retained engineer, managed the full scope to a tight timeline, and reported directly to the GC. It earned significant repeat work.

How it runs

How we run structural steel

  1. 01

    Design & drawings

    We produce engineered shop drawings through our retained engineer and pull permits when the scope requires them.

  2. 02

    Shore & prep

    We safely shore and prep the structure — proper jack-stand shoring and a clean, controlled work area.

  3. 03

    Fabricate & install

    We fabricate the steel and install it on site, tied back to the building and base-plated to spec.

  4. 04

    Inspect & close out

    We confirm the install is code-correct, clean up, and report completion to the GC.

Good to know

Structural Steel — questions we hear

Do you fabricate and install structural steel?

Yes. We fabricate and field-install structural steel and miscellaneous metals — platforms, stairs, handrail, reinforcement, tie-ins and supports — in the shop and on site.

Can you do engineered, permitted design-build?

Yes. We take projects from concept through engineered shop drawings and permits to a finished, code-correct install, reporting to the GC.

Do you build stairs, ladders and egress?

Yes — steel stairs, ship’s ladders, aluminum ladders, handrail, diamond-plate treads and bar-grating landings, tied back and base-plated to spec.

Can you reinforce for rooftop equipment?

Yes. We cut roof penetrations and design and install RTU and roof structural reinforcement as a permitted design-build scope.
