Spiral Pipe of Texas

What Spiral Pipe of Texas does

Spiral Pipe of Texas (SPOT) is a Fort Worth, Texas-based custom sheet metal fabricator founded in 1981 that produces commercial HVAC ductwork and related accessories. The company's core manufacturing platform uses spiral lock-seam construction with CAD/CAM detailing, plasma cutting, and MIG/TIG/spot welding to fabricate spiral round duct (3"–92" diameter, 26–16 gauge), spiral flat oval duct (3"–36" minor axis), rectangular/square duct, and specialty industrial ductwork including stainless (304/316), aluminum (3003), PVC-coated, and powder-coated variants. Differentiated product lines include the proprietary SPOT Flange™ connection system, the Gasket-Tite™ self-sealing connector (4"–24"), PhenoliDuct™ (closed-cell phenolic insulated duct integrating Kingspan KoolDuct® with R-12 value), and SPOT AgION™ antimicrobial-coated ductwork (EPA/FDA registered). All products are manufactured to SMACNA, ASHRAE 90.1, and SPIDA standards.

The company's go-to-market is sales-led and project-based. Experienced estimators provide quote-based pricing; project managers are assigned from quote through delivery. Products are sold to commercial and general contractors, mechanical and sheet metal shops, engineers and architects specifying duct systems, and industrial customers in healthcare, education, convention, and process/exhaust applications. Distribution is direct: truckload quantities are shipped to job sites, orders can be will-call picked up at the Fort Worth warehouse with published pricing on standard sizes, and a network of local sales representatives supports quoting and coordination across US coverage areas. SPOT is a pure fabricator and explicitly does not install products, avoiding competition with its contractor customers.

Revenue is generated primarily through one-time custom fabrication sales priced per project, with secondary standardized will-call pricing on commodity spiral pipe. Revenue is not publicly disclosed; the company is privately held with no institutional investors, subsidiaries, or M&A activity identified. Named enterprise projects include Cabela's (120,000 lbs of ductwork, ~2 months), Cowboys Stadium, Lewisville ISD Natatorium, University Medical Center Jackson, and convention centers in New Orleans, Oklahoma City, and Austin, indicating episodic but sizeable anchor contracts rather than recurring SaaS-style revenue.
