King Fabrication

What King Fabrication does

King Fabrication, L.L.C. is a privately held heavy specialty structural steel fabricator founded in 1997 and headquartered in Houston, Texas. The company operates from an 18-acre main facility at 19300 West Hardy Road with nearly 190,000 sq. ft. under roof, a separate marine yard on the Houston Ship Channel, and a dedicated 12,000 sq. ft. precision machine shop equipped for very large structural components. It sells one-off custom fabricated products and project-based services — not a catalog or license model — to enterprise and government customers in the Marine, Industrial (including Oilfield), Civil Engineering, and Energy sectors.

Its product portfolio spans marine structures, barges, unique and pedestrian bridges, architectural projects, spillway/floodgates and other hydroelectric components, and precision components sold to other fabricators. Underlying capabilities are organized into six service lines: Material Processing (Messer MPC2000 80-foot plate burning, Peddinghaus beam lines, sawing, drilling, beveling), Heavy Fabrication, Precision Machining (large-capacity grinders, horizontal boring mills, vertical turret lathe), Surface Preparation and Coating (SSPC QP3/QS1-certified blasting, hot-dip galvanizing up to 60-foot kettles, metalizing/thermal spray), Quality Control and Personnel Certification (AWS QCI inspectors, NDE Level II, NACE CIP I/II, phased array ultrasonic), and final Assembly up to 250 tons. Engineering design is integrated in-house via Tekla Structures, Rhino, Tekla FabSuite/EPM, AutoCAD, Fabtrol, and SolidWorks, enabling design-build and delegated design participation.

The business model is project-based B2B contracting with no public pricing. Go-to-market is enterprise field sales targeting large-scale infrastructure, marine, and industrial projects, with the marine yard enabling worldwide barge shipment (completed projects across five continents). Revenue is concentrated in custom one-off heavy fabrications rather than recurring license or subscription revenue. The company carries 20 certifications and has accumulated 15 named award-winning bridges, with recognition from bodies including AISC, ENR, AIA, Architectural Digest, the Chicago Athenaeum, and the Byway Organization. Owner-operator status and absence of disclosed outside funding indicate an independent, founder-controlled LLC.

Direct peers

• Hirschfeld Industries: One of the largest US structural steel fabricators, specializing in heavy bridge and industrial steel fabrication. Highly comparable to King Fab's core heavy fabrication and bridge work, though at meaningfully larger scale.
• Veritas Steel: Major US bridge and structural steel fabricator with multiple plants. Directly comparable to King Fab's signature bridge and heavy structural business, and overlaps on large plate-girder and arch bridge work.
• High Steel Structures: Pennsylvania-based heavy steel bridge fabricator serving DOTs and design-build projects. Comparable to King Fab in bridge focus and AISC-certified quality systems, though larger and more bridge-concentrated.
• Florida Bridge & Iron: Heavy structural steel and bridge fabricator based in Florida. Comparable to King Fab in producing award-winning bridges and heavy marine/industrial structures, with similar AISC-certified quality programs.
• ADF Group: Canadian structural steel fabricator serving bridge, industrial, and architectural markets in North America. Comparable to King Fab in complex architectural and structural steel projects, including design-build participation.
• Canam Group: Major North American structural steel and bridge fabricator with plants across the US and Canada. Comparable to King Fab's heavy structural and bridge work, though at materially larger scale.
• Trinity Marine Products: US-based manufacturer of marine barges and structural marine products. Directly comparable to King Fab's barge and marine structures product line, though Trinity operates at significantly larger scale.

Regional players

• Cimolai Group: Italian heavy steel fabricator with significant bridge, marine, and industrial work in Europe and select US projects. Comparable in technical capability (heavy plate, complex geometry) but primarily competes outside the US Gulf Coast market.

Others

• AISC-certified bridge fabricators (industry segment): The American Institute of Steel Construction certifies and lists ~60+ bridge fabricators that compete for similar DOT and design-build bridge work that King Fab targets. Industry association rather than a single competitor, but defines the competitive set.

Broad incumbents

• MasTec Industrial (Wanzek): Large diversified infrastructure and energy construction services firm with industrial fabrication capabilities. Overlaps with King Fab on oil & gas, marine, and heavy industrial projects, but as part of a much broader portfolio.
