What Southerntier Custom Fabricators does

Southerntier Custom Fabricators (STCF) is a privately held, family-owned custom sheet metal and HVAC air handling fabricator founded in 1982 in Elmira Heights, NY, and now operating from a 60,000+ square foot automated facility on 8½ acres in Elmira, NY. The company designs, fabricates, and delivers rectangular, spiral round, and oval HVAC ductwork, specialty fabrications, and its proprietary RUF Duct (a double-wall, foam-in-place pre-insulated outdoor duct system, UL-723 and ASTM E-84 certified) for commercial, industrial, institutional, healthcare, clean-room, and industrial-process customers. Core capabilities include CAD/CAM design linked to the Quickpen estimating system, Vicon 60" coil blanking and ductwork line, waterjet cutting (6'x12' and 12'x12' beds), Linde LM-250 plasma cutters, spiral machines up to 98" diameter, Iowa Precision Cornermatic and Whisperlock assembly equipment, automated bar code labeling, and AWS-certified MIG/TIG welding across ferrous and non-ferrous metals.

STCF operates a project-based B2B business with quote-driven pricing for work ranging from small walk-in jobs (with 72-hour component-part turnaround) to design/build industrial installations. Revenue streams span HVAC system fabrication, thermo-plastic fabrication (PVC, polypropylene, lexan, polycarbonate), component parts, steel materials supply (over 200,000 lbs of stock), welding/finishing services, and project tracking/delivery across the Northeast and Mid-Atlantic US (NY, NJ, Baltimore, Washington DC, NYC) and Ohio. Customer relationships are anchored by mechanical and sheet metal contractors, with secondary demand from K-12 and university facilities, hospitals, clean rooms, and emerging verticals such as cannabis cultivation (e.g., Curaleaf). The company maintains an owned delivery fleet including crane-equipped trucks for rooftop installation.

Leadership is held by second-generation President Ian Morrell (since 2016), with founder Art Morrell as Chairman, Director of Finance Jennifer McManus, and a senior team averaging 23 years in project management and 15 years in fabrication tenure. STCF has no institutional investors, no disclosed funding rounds, and no public financials; revenue derives entirely from custom manufacturing services and project-based contracts rather than recurring software or subscription revenue.
