What Locweld does
Locweld Inc., founded in 1947 in Candiac, Quebec, designs and manufactures steel lattice transmission towers, tubular steel poles, substation structures, and rock anchor solutions that form the backbone of the North American electrical grid. The company operates from a 220,000 square foot manufacturing facility with 210+ employees and has produced more than 100,000 lattice towers supporting over 20,000 miles of transmission lines across the United States and Canada.
The company's capabilities span the full lifecycle from in-house structural design and load analysis through steel fabrication (cutting, welding) and project management. Its four core product lines — Lattice Structures, Steel Poles, Substation Structures, and Rock Anchor — are engineered as custom solutions for varied voltage levels and terrains, with quality control and compliance to industry grid standards. Locweld sells primarily to electric utilities, power transmission companies, and grid operators, with secondary exposure to government-funded infrastructure projects. Pricing is project-based and not publicly disclosed; commercial engagement runs through direct enterprise field sales and industry events.
In May 2025, Locweld was acquired by Stella-Jones Inc. (TSX: SJ) for $58 million cash-free, debt-free with potential additional performance-based payments of up to $7 million, and now operates as the cornerstone brand of Stella-Jones' Steel Structures division. Stella-Jones committed $15 million in capital investment to expand Locweld's operational capacity, and the company has subsequently announced a new greenfield U.S. manufacturing facility to extend its geographic footprint.

Locweld competitors and assessment
Company assessmentBroad incumbents
- KEC International: Indian EPC and transmission tower manufacturer with global operations, parent of SAE Towers. Competes with Locweld on lattice tower supply for utility-scale projects worldwide and provides a broader EPC service offering that bundles towers with construction.
- Quanta Services: Large publicly-traded infrastructure services company that designs, installs, and maintains electric power infrastructure, including sourcing lattice towers and poles for utility projects. Adjacent competitor and major customer-side channel for transmission structures.
- Valmont Industries: Large, publicly-traded diversified manufacturer of engineered support structures including utility transmission and distribution poles, lattice towers, and substations. Overlaps with Locweld on steel poles and lattice structures, but competes across a much broader portfolio (irrigation, coatings, lighting).
Direct peers
- DIS-TRAN Steel: US manufacturer of substation and transmission steel structures, including lattice towers and pole structures, serving electric utilities. Directly comparable in fabricated structural steel products for grid infrastructure, though with a heavier tilt toward substation structures.
- Sabre Industries: US-based manufacturer of steel lattice transmission towers, tubular steel poles, and substation structures for electric utilities. Directly comparable in product scope, customer base, and engineering-driven project model, with significant presence across North America.
- SAE Towers: A wholly-owned subsidiary of KEC International and a leading global manufacturer of steel lattice transmission towers and monopoles. Directly competes with Locweld for utility-scale transmission projects in North and South America, with comparable engineering and fabrication capabilities.
- Brooks Manufacturing Co. A North American manufacturer of steel lattice towers and substation structures, now part of Stella-Jones' Steel Structures division alongside Locweld. Directly comparable as a sister brand serving the same utility transmission customer base with overlapping product lines.
- Power Transmission Solutions Inc. North American fabricator of transmission and distribution steel structures serving utilities and EPC contractors. Overlaps with Locweld on lattice towers and substation structures with comparable project-based sales model and engineering-to-fabrication scope.
Emerging players
- Mitas Industries: North American manufacturer focused on steel monopoles and related structures for transmission, distribution, and lighting. Partially overlaps with Locweld's tubular steel pole and lattice structure product lines, particularly in the US market.
Regional players
- Trinity Steel: Manufacturer of steel utility structures including transmission poles and lattice components serving US utilities. Comparable in fabrication capabilities and customer base, with a primarily US footprint, though smaller scale than Locweld.
