What Shawflex does

Shawflex is a Canadian manufacturer of custom engineered electrical wire, cable, and assembly solutions, operating as a wholly-owned division of Mattr Corp. since its founding in 1960. The company produces CSA and UL certified armoured and unarmoured cables spanning Teck 90, TC Tray, LSZH, building wire (RW90/RWU90/XHHW-2), and nuclear-grade (EQ Class 1E) variants, complemented by custom cable assemblies, terminations, and harnesses manufactured through its Kanata Electronic Services subsidiary. With approximately 14,000 unique parts and 167 billion documented cable design possibilities, Shawflex serves customers across nuclear power (CANDU and advanced reactors), aerospace (including space-grade wire harnesses for NASA's Canadarm2 and Space Shuttle Discovery), marine shipboard, mining, transit/railway, EV infrastructure, renewable energy, telecommunications, utilities, and general industrial verticals across 35+ countries.

The company operates a dual business model combining make-to-order catalog products with engineer-to-order bespoke solutions, with pricing conducted via quote for custom work and not publicly disclosed. Revenue is generated through direct enterprise field sales for custom engineered products targeting major industrial projects (with named customers including NASA, Bruce Power, Westinghouse Electric, and the Jack & St. Malo deepwater project), supported by a channel partner network for catalog distribution. Technical differentiators include nuclear-grade Class 1E safety cables, high-temperature and high-radiation resistant designs, LSZH halogen-free constructions, VFD power cables, Safe-T-Ground fire-resistant grounding systems, and vertical mineshaft cables; the company holds a broad stack of CSA, UL, IEEE, and ICEA certifications and participates in the Copper Mark sustainability framework.

In 2025 Shawflex is executing two materially significant strategic moves: relocating to a new 240,000 sq ft state-of-the-art manufacturing facility in Vaughan, Ontario (expanding from 140,000 sq ft) and signing an MoU with Westinghouse Electric to supply cable and assembly solutions for AP1000, AP300, and eVinci advanced reactor projects in Canada and globally.
