Structural Steel Fabrication & Erection
The structural backbone behind our light gauge steel builds: in-house structural steel and seismic engineering for when projects go higher or need lateral reinforcement. LA City Approved, handled from shop drawing to set frame.
The force multiplier that takes light gauge steel higher.
Most of what we build is light gauge steel. Structural steel is how we take those projects further: the beams, columns, and connections that carry heavier loads, add stories, and solve the lateral and seismic reinforcement an LGS frame alone can't. It's the backbone behind our panelized builds.
That capability is rooted in a seismic-retrofit heritage: in-house structural engineering, AWS D1.1 certified welding, and field erection, delivered end to end from shop drawing to set frame, on time and to code.

From shop drawing to set frame, one accountable team.
We carry structural steel end to end, so detailing, fabrication, and erection stay coordinated and on schedule, with no handoff to a separate fabricator or erector.

Detailing & BIM
Connection design and shop drawings modeled in BIM and coordinated with the structural engineer of record.

Shop Fabrication
Beams, columns, and base plates cut, drilled, and welded to AWS D1.1 in our own facility.

Delivery & Rigging
Members sequenced, trucked, and staged to the erection plan so the frame goes up in order.

Field Erection
Our ironworkers set, plumb, bolt, and field-weld the frame, with crane coordination and in-house QC.
Precision fabrication, from base plate to building frame.
In our 100,000 square foot facility, raw steel becomes installation-ready components, cut, formed, welded, and assembled to exact spec, then shipped ready to set.
Structural Beams & Columns
Fabrication of load-bearing I-beams, H-beams, and columns engineered to spec.
Steel Building Frames
Complete structural frames for warehouses, commercial, and industrial structures.
Base Plates & Connections
Precision-cut base plates and structural connectors for accurate field fit-up.
Custom Fabrication
Brackets, reinforcements, and engineered components built straight to the drawing.
Industrial Steel Systems
Structural support systems for heavy-duty industrial applications and equipment.
Cutting, Forming & Welding
Sawing, shearing, forming, oxy-fuel, plasma cutting, drilling, and certified welding into finished assemblies.




Field installation that brings the frame to life.
Cal Steel does not just fabricate, we erect. Experienced ironworkers and field supervisors install your steel safely, accurately, and on schedule, in close coordination with your general contractor.
Structural Frame Installation
Complete frame assembly and positioning, set true to line and grade.
Beams, Columns & Joists
Primary load-bearing member placement and connection.
Metal & Roof Decking
Metal deck and roof deck systems installed and fastened.
Mezzanine & Platform Erection
Multi-level structural systems for added floor area and access.
Anchor Bolts & Base Plates
Foundation connections set accurately for a true, plumb structure.
Crane Coordination & Rigging
Equipment logistics and safe material handling on site.
Plus field welding and bolting, structural modifications and reinforcement of existing structures, and tenant-improvement steel erection for commercial retrofits.




Certified crews. Code compliance. No shortcuts.
Every project is delivered with certified oversight and clear communication with your general contractor. As the steel arm of TESH Group, Cal Steel pairs that discipline with an owned production base, from master coil to finished, erected assembly.
AWS D1.1 Certified Welding
Certified welders, GMAW (MIG), SMAW (Stick), and FCAW (Flux-Core), in shop and in the field.
Experienced Ironworkers
Trained erection crews and field supervisors with structural expertise.
OSHA-Compliant Safety
Proper rigging, welding procedures, anchoring, and jobsite cleanliness, enforced.
Insured & Bonded
Fully insured and bonded operations for confident project delivery.
BIM-Integrated Detailing
3D modeling fully integrated with established BIM processes.
In-House Quality Control
QC from shop drawings through field signoff, under one accountable team.

823 North June Street. Structural steel and light gauge steel, combined.
A four-unit, three-story residential infill building: a structural steel garage level engineered to carry two panelized light gauge steel floors above. The same team, the same jobsite, structural and light gauge steel working together, delivered as a panelized package and assembled on site in days.

777 Ocampo Drive. A rebuild framed entirely in steel.
Working behind an outside general contractor, Cal Steel is delivering the complete structural steel and light gauge steel package: from a deep basement and its custom curved steel stair up through the second-floor structure. Beams, columns, embed plates, and connections detailed, fabricated, and erected by the same team that frames the panels around them.
