Structural Steel Fabrication Services
Single-source structural steel fabrication — PE-stamped engineering and AISC 303 shop drawings in-house, fabrication managed through our network of AISC-certified shops with AWS D1.1 certified welders. Beams, columns, stairs, platforms, and equipment supports — delivered nationwide. Fixed-fee quotes in 48 hours.
What is structural steel fabrication?
Structural steel fabrication is the cutting, bending, welding, and assembly of rolled steel shapes — W beams, HSS columns, channels, angles, and plates — into the beams, columns, braces, stairs, and platforms that make up a building's frame. The work is governed by AISC 360-22 (design), AISC 303 (Code of Standard Practice for shop drawings), and AWS D1.1 (welding).
We deliver structural steel fabrication as a single-source package. The PE-stamped connection design and AISC 303 shop drawings are produced in-house by our California-licensed Professional Engineers; fabrication is managed through our vetted network of AISC-certified shops with AWS D1.1 certified welders. One contract, one point of contact, one chain of custody from S-sheet to jobsite — and shop selection matched to project geography to keep freight reasonable on nationwide projects.
Who we work with
- • General contractors needing single-source steel
- • Owners and developers (commercial, industrial, healthcare)
- • EPC firms on industrial and energy projects
- • MEP contractors needing equipment support steel

Structural steel fabrication — frequently asked questions
What is structural steel fabrication?
Structural steel fabrication is the process of cutting, bending, welding, and assembling rolled steel shapes (W, HSS, channels, angles, plates) into the beams, columns, braces, stairs, platforms, and miscellaneous supports that make up a building's structural frame. The work is governed by AISC 360-22 (steel design), AISC 303 (Code of Standard Practice), AWS D1.1 (welding), and the project's structural drawings — and on essential or seismic-classified projects requires PE-stamped connection design and shop drawings. We deliver structural steel fabrication as a single-source package: PE-stamped engineering plus managed fabrication through AISC-certified partner shops, shipped nationwide.
Do you fabricate the steel yourselves or just design it?
Both. We provide the PE-stamped connection design and AISC 303 shop drawings in-house, then manage fabrication through a vetted network of AISC-certified fabrication shops staffed with AWS D1.1 certified welders. You get a single point of contact for engineering, drawings, fabrication, QA, and shipping — instead of coordinating an engineer, a detailer, and a fab shop separately.
Are your fabrication shops AISC certified?
Yes. Every shop in our network holds active AISC certification (STD / BU / IBR / CMF as appropriate to the work) and operates under AWS D1.1 prequalified welding procedures with certified welders. We select the shop based on project scope, tonnage, schedule, and shipping geography — not a fixed location — which keeps freight cost down and lead times short.
Do you provide steel connection design?
Yes. We deliver PE-stamped delegated connection design per AISC 360-22 Chapter J — shear tabs, single and double angles, end plates, moment connections, brace gussets, base plates, and HSS slotted connections. Each connection is designed to the required strength noted on the structural drawings (or to AISC standard maximums when SER-of-record requests), with weld and bolt sizes calculated and shown on the shop drawings.
Do you produce steel shop drawings?
Yes — we produce AISC 303 compliant shop drawings and erection drawings for fabricators, including assembly drawings, single-part details, anchor bolt setting plans, bill of materials, and weld symbols per AWS A2.4. Drawings are issued in PDF + DWG/DXF and CNC-ready (DSTV/NC1) where the shop runs a beam line, drill line, or coper.
What miscellaneous steel do you design and detail?
Misc steel includes stairs (egress and architectural), guardrails and handrails, ladders, mechanical equipment platforms and dunnage, roof screens, lintels, embed plates, pipe supports, and equipment skids. We design these to AISC 360-22 + IBC 2021 Chapter 16 loads (including ASCE 7-22 seismic Fp on supported equipment) and detail them for shop fabrication.
Do you handle seismic-rated steel supports for equipment?
Yes. Steel rails, frames, dunnage, and curbs supporting nonstructural equipment must transfer the ASCE 7-22 §13.3 Fp force into the building structure. We design the steel members and welds for combined gravity + seismic + wind, including Ω0 amplification on connections of essential equipment (Ip = 1.5), and coordinate the anchorage to concrete per ACI 318-19 Chapter 17.
What deliverables come with a structural steel package?
Engineering: PE-stamped connection design calculation report, AISC 303 shop and erection drawings (PDF + DWG/DXF), CNC files (DSTV/NC1), AWS D1.1 prequalified WPS references, bolt and weld schedules, anchor bolt setting plan, and a bill of materials. Fabrication: mill test reports (MTRs), AWS-certified welder logs, AISC shop QA records, surface prep / paint / galvanizing per spec, and palletized shipment with piece-mark manifest. Special inspection coordination per IBC Chapter 17 on request.
Do you ship fabricated steel nationwide?
Yes. We coordinate fabrication through partner shops geographically matched to the project to minimize freight, then ship anywhere in the continental US (and Hawaii / Alaska / Canada on request). Loose pieces ship on flatbeds with piece-mark manifest; large assemblies ship as oversize loads with permit routing handled.
How fast can you turn shop drawings and connection design?
Engineering only (connection design + shop drawings): 2–3 weeks for a typical ≤ 50-ton commercial package; 5–10 business days for misc steel (stairs, platforms, supports). Engineering + managed fabrication: add 4–8 weeks for fabrication and shipping depending on tonnage, finish (mill / paint / hot-dip galvanized), and shop queue. Send the structural drawings (S-sheets), specifications, and a tonnage estimate — fixed-fee quote in 48 hours.
