Sheet Metal Connectors

What Sheet Metal Connectors does

Sheet Metal Connectors, Inc. (SMC) is a Minneapolis, Minnesota-based fabricator of standard and custom commercial and industrial HVAC sheet metal ductwork, founded in 1969 by Jerry Myers as a three-employee shop and now operating 175+ employees across three sites. The company manufactures spiral pipe and fittings (including the proprietary E-Z Flange and Complete Seal gasket systems), rectangular duct and fittings in TDC, Slip/Drive, and Raw styles, double-wall and rectangular double-wall duct, PVS (polyvinyl-coated) duct, flat oval spiral, phenolic-lined Thermaduct and KoolDuct, plus accessories such as dampers, louvers, turning vanes, and the EZ RAIL system. Underlying technology centers on 4-ply spiral lockseam pipe formation (delivering roughly 2.5x the crush resistance of welded pipe), factory-installed EPDM gaskets that meet SMACNA Leakage Class 3, optional PVC coating that lifts rigidity by approximately 300%, and pre-fabrication workflows intended to reduce field labor by 15-20%.

SMC sells business-to-business to HVAC contractors and mechanical companies, with a primary go-to-market of direct sales via toll-free phone, email, and on-site project consultation, supported by a proprietary self-serve platform called PriceDuct that delivers instant quotes and online ordering with steel-price-indexed pricing. Revenue is generated through three streams: catalog hardware sales, custom fabrication services (welding, end treatments, fitting design), and PriceDuct online sales. Pricing is unit-based for standard items and quote-based for custom work and large orders, with technical and customer support available 7 a.m. to 4:30 p.m. Central. End-uses span stadiums, sports and entertainment venues (U.S. Bank Stadium, Target Field, AMSOIL Arena), universities, K-12 schools, multi-family housing, hospitality, retail, restaurants, warehouses, manufacturing, and greenhouses and indoor farms.

The company is privately held and operates as a yellow-label union shop, with manufacturing in Minneapolis, MN and Rockford, IL plus a Damper and Louver Division operated as Standard Metal Products. Jim Myers, the founder's son, became President and CEO in 2015, restoring second-generation family leadership. SMC holds multiple patents (Complete Seal, Super Heto, EZ RAIL) and positions itself as both a regional duct manufacturer and a national component manufacturer, distributing exclusively within the United States.

Direct peers

• McGill AirFlow: One of the largest North American commercial HVAC ductwork manufacturers, producing rectangular and spiral duct, fittings, and accessories. Direct competitor to SMC in commercial sheet metal duct fabrication, with broader national plant footprint.
• Ductmate Industries: Manufacturer of HVAC ductwork components and connection systems (including pre-engineered connection technologies analogous to SMC's E-Z Flange). Comparable as a duct component/connection-systems peer with proprietary product platforms.
• Semco Ductwork: Specialty spiral ductwork manufacturer serving commercial and industrial HVAC. Closely comparable to SMC's spiral pipe and fittings business with a similar product focus and contractor customer base.
• Eastern Sheet Metal: Regional commercial HVAC sheet metal fabricator producing rectangular duct, spiral pipe, and custom fittings for contractors. Comparable in product mix, customer type, and mid-size regional fabricator profile.
• Hamlin Sheet Metal: Commercial/industrial sheet metal HVAC fabricator producing spiral and rectangular ductwork, fittings, and accessories. Comparable in product line, custom fabrication services, and contractor-led GTM.

Broad incumbents

• Lindab (HVAC division): European-based global HVAC ductwork manufacturer with broad product portfolio including rectangular duct, fittings, and accessories. Comparable in core commercial HVAC ductwork, with broader international scale than SMC.
• Greenheck Fan Corporation: Major commercial HVAC equipment manufacturer offering fans, dampers, louvers, and air-handling equipment — overlapping with SMC's damper/louver subsidiary (Standard Metal Products) and broader HVAC product mix.
• Titus HVAC: National manufacturer of air distribution products (diffusers, grilles, terminal units, dampers). Comparable as part of the broader commercial HVAC air distribution value chain in which SMC supplies ductwork upstream.
• Ruskin Company: Manufacturer of commercial HVAC dampers, louvers, and air control products. Overlaps with SMC's Standard Metal Products damper and louver division and competes in the same commercial HVAC product categories.

Others

• Koch Filter Corporation: Manufacturer of HVAC air filtration products and accessories. Adjacent/complementary rather than directly competitive — comparable as a U.S.-based specialty HVAC component supplier serving similar mechanical contractor channels.
