Mattr

Mattr is a global materials technology company that combines specialist manufacturing capabilities, advanced material technologies and market-leading brands to produce engineered solutions for demanding infrastructure projects. The company traces its history back to 1968 and was formerly known as ShawCor Ltd.; it now trades as Mattr, reflecting a broader ambition. It is led by President and CEO Mike Reeves.

Mattr's operations span engineered wire and cable manufacturing, heat-shrink and cold-shrink tubing technology, spoolable composite linepipe and fiberglass storage tank manufacturing. Its brands include Shawflex, which makes engineered wire, cable and assemblies; AmerCable, which supplies electrical power, control and instrumentation cables; DSG-Canusa, which produces heat-shrink and cold-shrink tubing; Flexpipe, which makes spoolable composite linepipe; and Xerxes, which manufactures fiberglass fuel and water storage tanks and stormwater management solutions.

The company's work serves a range of infrastructure-dependent sectors, among them electrification, transportation, mining, energy, communications and water management. In January 2025 Mattr acquired AmerCable, establishing its United States wire and cable manufacturing footprint. Its geographic presence is described as global, with a growing position in the United States.

Mattr states that it builds around differentiated materials technologies, manufacturing expertise and brands positioned to lead their respective markets.
