What We Do

Two divisions, one standard

Commercial structural steel and industrial fabrication and construction, from raw material to code-stamped vessels, delivered by the same crews held to the same standard.

Structural Steel

Steel Fabrication

Custom beams, columns, frames, and assemblies fabricated to engineered drawings, the load-bearing backbone of industrial and commercial projects, built to spec and built to last.

Field Construction

Onsite erection, structural install, and field construction managed end to end. We bring the crews, equipment, and project discipline to deliver industrial and commercial work safely and on schedule.

Industrial Fabrication & Construction

Pressure Vessels

ASME Section VIII, Division 1 pressure vessels built under our U stamp. Rolled, welded, and tested to code with full material traceability and documentation.

Process & Power Piping

B31.3 process and B31.1 power piping spools cut, beveled, fit, and welded by procedure-qualified welders, then delivered to the site ready to set.

Plant Maintenance & Turnarounds

National Board R stamp repairs and alterations to installed vessels and piping. Shutdown and turnaround support from crews that show up ready and finish on schedule.

Industrial Field Installation

Setting vessels and equipment, field pipe welding and tie-ins, rigging, and mechanical installation, the construction half of industrial work, self-performed.

Codes & Certifications

Qualified to the code the job is built to

Pressure work is only worth what its documentation proves. Every vessel, spool, and repair leaves our shop with the procedure qualifications and traceability the code requires.

ASME Section VIII, Div. 1
U stamp - new pressure vessel construction.
National Board
R stamp - repair and alteration of pressure-retaining items.
ASME B31.3
