Sippel Steel Fab

What Sippel Steel Fab does

Sippel Steel Fab is a privately held, AISC-certified structural steel fabricator headquartered in Ambridge, Pennsylvania, founded in 1985 following earlier origins in weld repair and light fabrication. The company operates an integrated four-service platform spanning in-house Detailing (SDS2 3D modeling, connection design, shop drawing generation, BIM coordination, and stair/rail design), Engineering (delegated connection design, design-build solutions, and design-assist), Fabrication (AISC Building BU and Bridge SB certified, AWS D1.1 welding, CNC plasma/oxy-fuel processing, CNC multi-spindle drilling, cambering, and heavy-lift capability with 16 cranes up to 80 tons handling members of 50+ tons), and Painting (AISC Complex Coating Endorsement, industrial blasting, high-performance coatings, and AESS architectural finishes). Its Ambridge shop occupies a former American Bridge Fabrication site on the Ohio River that has been modernized over 25 years into a multimodal barge, rail, and trucking logistics hub optimized for oversized inbound raw materials and outbound project loads.

The company targets large, complex structural steel projects that require sophisticated connection design, oversized members, constrained urban sites, and tight construction schedules. Documented project work spans healthcare (UPMC Presbyterian, Allegheny Health Network Wexford, MetroHealth, Cleveland Clinic Taussig Cancer Center), commercial high-rise (PNC Tower), sports and entertainment (University of Notre Dame Stadium), transportation infrastructure (Pittsburgh International Airport Terminal Modernization), and industrial manufacturing (Mercedes-Benz Van Plant in Ladson, SC). Customers are enterprise general contractors and project owners engaged through design-assist and design-build delivery methods during early design phases, with project-based quote pricing and no standardized product tiers.

Sippel generates revenue through one-time project contracts rather than recurring licensing, with project values implied by single contracts ranging from approximately 2,300 to 16,500 tons of structural steel (e.g., Pittsburgh International Airport at 16,500 tons and UPMC Presbyterian at 10,200 tons). With 51-100 employees and no disclosed external funding, the company has grown organically over 40+ years, leveraging AISC and AWS certifications, capital-intensive heavy-lift infrastructure, and an Ohio River logistics position to compete for structurally complex bids that smaller or non-certified fabricators cannot pursue.
