Light-gauge steel fabrication forms the basis of the A-Linx modular building system.
A-Linx’s modular building system is structured around a light-gauge steel (LGS) manufacturing process that shifts major stages of construction into a controlled factory environment. The system uses prefabricated exterior, interior and load-bearing wall systems, along with roof trusses, to support different building types. Designed to meet the National Building Code of Canada, the platform can be applied to ADUs, medium-density housing and multi-storey developments of up to 20 levels, placing A-Linx among a limited group of Canadian modular construction manufacturers able to operate across this range. (main image: 42 Mill Street in Georgetown, Halton Hills, Ontario, was constructed using the modular building system by A-Linx, combining a light-gauge steel frame with COMSLAB flooring. The six-storey building is 108,000 sqft (10,033 sqm) with 76 units.)
The manufacturing workflow begins with BIM-based coordination that resolves services pathways, structural requirements and panel dimensions prior to fabrication. Cold-formed steel components are then produced with defined openings and service penetrations. As the company states, “Our tighter tolerances and precision assembly processes dramatically reduce site issues, allowing your project to advance with previously unthinkable speed, accuracy and economy.”
Production Manager Matthew Pellitteri notes that the method is built around predictable performance rather than predefined geometries. “From inception, when we start dealing with our clients, we hold true to the promises that are made. What we promise them is a superior quality product that can go in more quickly and is more economical than what is traditionally used.”
A key feature of the A-Linx modular building system is its adaptability. Instead of relying on standardised module sizes, A-Linx configures its assemblies around the project. Pellitteri describes this directly: “The client does not have to design around our system; we design around theirs.” This flexibility allows the LGS building system to support varied site conditions, layouts and unit mixes across residential and mixed-use developments.

Factory sequencing and shorter on-site programmes
A-Linx structures its production sequencing so that substantial parts of the construction timeline occur in the factory. Panels for upper storeys can be manufactured while lower levels are being installed. Pellitteri explains the approach: “As they are on the first floor, we have already fabricated the third and fourth floors.” If design changes arise, adjustments can be incorporated during fabrication, reducing disruption once installation is underway.
Installation on site often progresses quickly once panels are delivered. Superintendent Eric Parrault describes the process: “It shows up preassembled; you just fly it into place, and in two weeks you have an entire floor.” This method also reduces exposure to winter conditions. As Glos Associates’ Shane Mitchell says, “If the panels are prefinished, you can erect them in the rain or the snow… with the A-Linx system, we can erect a building throughout the winter.”
Given that A-Linx is a division of Amico, site installation is carried out by Amico Design-Build teams. Amico Design-Build Superintendent Gilbert Hofman highlights the continuity this creates: “We used the same 18 people on site. It takes them no time to understand the system. When it comes to the next section, they automatically know what to do.” With services apertures integrated during fabrication, mechanical and electrical trades progress in parallel with the structural assembly.
Habitat for Humanity Windsor Essex applies the system to a multi-home programme
The A-Linx modular building system will be used in a collaboration with Habitat for Humanity Windsor Essex to construct 16 homes for a development in Amherstburg, Ontario. Units will be produced in the Oldcastle facility before being transported to site once foundations are complete. Habitat continues to explore modular construction in situations where controlled production and defined installation processes support predictable outcomes for homeownership projects.
While this is one of several initiatives the organisation has undertaken, it illustrates how an LGS building system can operate within multi-unit delivery settings requiring repeated fabrication and coordinated installation. For A-Linx, the programme shows the application of factory-led workflows to a structured housing model.
Justin Amicone, General Manager at Amico Design Build and A-Linx, described the programme as “a demonstration of how Canadian manufacturing capacity can be applied to the housing challenge”, noting the potential for it to serve as “a replicable model for regions across the country.”
A system designed for consistent application across building types
The A-Linx modular building system uses digital coordination, light-gauge steel fabrication and offsite assembly to establish a consistent production workflow from design through to installation. Its three Ontario facilities operate with the same manufacturing approach, allowing projects to be delivered with defined tolerances and coordinated sequencing. The combination of panelised fabrication and controlled assembly conditions provides a repeatable method that can be applied to different building types and project requirements.
