Tendon Systems

What Tendon Systems does

Tendon Systems, operating as CMC Cable, is a US-based post-tensioning solutions provider and division of publicly-traded Commercial Metals Company (CMC, founded 1915). The company supplies fabricated, unbonded post-tension cable and related systems to commercial and residential construction industries, with applications spanning slab-on-grade foundations, bridges, buildings, parking structures, and rock-and-soil anchors. Its core product portfolio includes Unbonded Monostrand Systems (high-density polyethylene-sheathed tendons per ASTM/PTI standards), Encapsulated Systems for corrosive environments (coastal areas, parking garages with de-icing salts), Multistrand and Specialty Systems, and the trademarked Shearail shear stud reinforcement product designed per ACI 421.1R99 guidelines to eliminate shear capitals in flat plate slabs.

The company operates four PTI (Post-Tensioning Institute) certified fabrication facilities located in Fontana, CA; Fort Myers, FL; Suwanee, GA; and Belvidere, IL, giving it nationwide production coverage. Tendon pairs its hardware portfolio with in-house engineering services covering design preparation, field installation drawings, cost estimation, pour layout and sequencing, and value engineering during the preconstruction phase. Additional service lines include barrier cable installation, concrete scanning and coring, and restoration services for existing post-tension systems. Through parent CMC, the company also participates in adjacent product lines including ChromX, GalvaBar, CryoSteel, and the TruSHIELD/TruSTRENGTH/TruWEAR performance steel brands, plus wholly-owned subsidiary Tensar for geotechnical and ground improvement solutions.

The go-to-market is sales-led and project-driven. Pricing is quote-based rather than published, with revenue derived from two streams: hardware sales of fabricated post-tension cable and related accessories, and professional services revenue from preconstruction engineering. Marketing is conducted through the company website (featuring a Request a Quote function), direct phone contact at each fabrication facility, and active participation in industry associations including PTI, ACI, and AGC. Customer segments are organized horizontally across commercial construction, residential construction, and specialty geotechnical applications, with no public disclosure of named end customers or revenue concentration.
