What size steel jobs do you take on?

We routinely run packages from a few hundred tons up to multi-thousand-ton stadium and healthcare projects. We are sized to put multiple raising gangs on one site when the schedule demands it.

Are your ironworkers union?

Yes. Our raising and decking crews are signatory union ironworkers with the welding and rigging certifications healthcare, civic, and stadium owners require.

Do you handle steel and precast on the same project?

Frequently. Many of our hospital, parking-deck, and stadium projects combine structural steel and structural precast in a single Assemblers Group scope.

Structural Steel Erection

Precision installation of structural steel for commercial, industrial, and large-scale infrastructure — backed by certified ironworkers and decades of field experience.

From single-story tilt-up retrofits to multi-story steel frames over occupied campuses, Assemblers Group handles steel erection as a tightly choreographed sequence: deliveries staged to match the lift plan, crews sized to the daily piece count, and a foreman responsible for plumb, bolt-up, and weld QC at every connection.

We work shop drawings cooperatively with the fabricator and engineer of record, flagging conflicts before they hit the field. On healthcare, education, and stadium projects we have completed steel erection inside live campuses with strict safety, noise, and access constraints.
