Corner Cast

What Corner Cast does

Corner Cast is a privately held Canadian engineering and construction firm founded in 2011 in Montréal, Québec, specializing in modular steel structures fabricated from modified shipping containers. The company designs, engineers, fabricates, and installs turnkey modular buildings for industrial and commercial clients, with a product portfolio spanning Hybrid Container Structures (clear-span steel frames on container foundations), Modular Building Complexes (interconnected container facilities), Custom Container Units (specialized single-container modifications), and Fabric Building dome structures. Core technology relies on COR-TEN steel containers combined with steel superstructures to deliver relocatable, foundation-free buildings that arrive approximately 95% complete with HVAC and electrical pre-integrated.

The company serves enterprise and government customers across eight primary verticals: mining (Agnico Eagle, Rio Tinto, Alcoa, I AM Gold, Stornoway, Cliffs, Newgold), military (Canadian National Defence), aerospace (Bombardier, CAE), port and terminal operations (Termont Logistics at Port of Montréal), railways (CN), water treatment (H2O Innovation, Ville de Montréal), renewable energy, and commercial (Tangerine pop-up banks, Sobeys, University of Manitoba). Corner Cast is part of the PROCO group of companies, which provides access to more than 400,000 square feet of production space and North America-wide labor mobilization. The company has delivered over 260 custom container complexes globally, with projects in Canada, the United States, the Czech Republic, Suriname, and Jamaica, and has won Modular Building Institute Awards of Distinction in 2017, 2019, 2020, 2021, 2022, and 2024.

Corner Cast generates revenue primarily through custom project-based contracts for hardware fabrication and delivery, supplemented by bundled professional services (engineering, inspections, project management, permitting support, transportation, and maintenance). Pricing is non-standardized and determined per project after needs assessment, with billing structured around multi-year contracts for larger engagements. The go-to-market is enterprise direct sales with industry-dedicated landing pages and consultative project management from concept through installation; there is no consumer or self-serve channel, and pricing is not publicly disclosed. The company holds Modular Building Institute membership and E-Rail Safe certification for railway deployments.

Core offering

Corner Cast designs, engineers, fabricates, and installs modular steel structures built from modified shipping containers and hybrid container-and-fabric systems. They deliver turnkey projects—from concept and architectural drawings through fabrication, transportation, and on-site installation—for industrial and commercial clients in remote and challenging environments. Offerings include hybrid container structures, modular building complexes, custom container units, and fabric buildings.

Product overview

Corner Cast offers a portfolio of modular steel construction solutions using shipping containers as primary building elements. The product line consists of three core offerings: Hybrid Container Structures (steel clear-span buildings with container foundations), Modular Building Complexes (interconnected container-based facilities), and Custom Container Units (specialized modified containers). Additionally, the company provides Fabric Buildings for warehousing applications. All products can be customized, are relocatable, require minimal or no foundations, and are designed for rapid deployment across industries including mining, military, aerospace, port operations, railways, and commercial sectors. The company also offers comprehensive services spanning design, engineering, fabrication, transportation, installation, and maintenance.

Differentiator

Problem solved

Functional benefit

Products and services

• Hybrid Container Structures Steel structures that combine a clear-span frame with modified container foundations, eliminating the need for conventional foundations while maximizing interior usable space for industrial and commercial clients.
• Modular Building Complexes Multifunctional facilities composed of interconnected shipping containers modified and assembled to create larger open spaces, featuring COR-TEN steel construction, stackable design, and minimal foundation requirements for industrial and commercial use.
• Custom Container Units Specialized modified shipping containers tailored to specific requirements including doors, windows, insulation, and utility connections for industrial and commercial applications, with modular flexibility, durability, stackability, and reusability without requiring foundations.
• Fabric Buildings Insulated fabric dome structures used for warehousing and storage applications, featuring galvanized steel framework and fire-retardant HDPE fabric or steel roofing options. Offered both as standalone fabric structures and as hybrid solutions combined with container foundations.
• Turnkey Modular Construction Services End-to-end project services including building inspections, engineering, construction supervision, quality control, permitting support, project management, transportation and logistics, and maintenance, bundled with construction projects or offered separately to enterprise and government clients.

Direct peers

• Sprung Instant Structures: Sprung designs and manufactures engineered membrane/steel structures for industrial warehousing, mining camps, and remote-site applications. Comparable to Corner Cast's Fabric Buildings line and its hybrid steel/structural offerings for mining and energy customers.
• Alaska Structures: Alaska Structures manufactures fabric-engineered buildings and modular container-based structures for military, mining, oil & gas, and remote industrial applications — overlapping directly with Corner Cast's primary segments of military, mining, and remote industrial.
• Vanguard Modular Building Systems: Vanguard provides modular buildings and relocatable structures for commercial, industrial, and institutional clients across North America, with turnkey installation. Direct comparable on modular construction delivery model and customer base (commercial, institutional).
• Giant Containers: Giant Containers fabricates modified shipping containers and modular container-based structures for commercial, industrial, and remote-site applications. Direct comparable on container-modification engineering and on Corner Cast's core product line.
• ATCO Structures & Logistics: ATCO's Structures & Logistics division delivers modular buildings, workforce housing, and relocatable industrial structures globally — the closest direct comparable to Corner Cast's container-based modular and turnkey installation model, particularly in mining, energy, and defence.
• ConGlobal Industries: ConGlobal modifies and repurposes shipping containers for industrial, logistics, and infrastructure uses — including site offices, equipment enclosures, and specialized structures. Direct comparable on container modification and on-site industrial infrastructure delivery.
• Satellite Industries: Satellite Industries manufactures portable and modular buildings (offices, storage, workforce housing) for construction, industrial, and events markets. Comparable on modular/portable building manufacturing and rental, though more standardized and less hybrid than Corner Cast.

Emerging players

• Boxabl: Boxabl produces factory-built container-folded housing units targeting residential and light commercial markets. Overlaps with Corner Cast on shipping-container-as-primary-structure philosophy but is focused on housing rather than industrial/infrastructure applications.

Broad incumbents

• Modulaire Group: Modulaire (formerly Algeco) operates one of the largest modular-space rental fleets in Europe and globally, serving industrial, public-sector, and construction customers. Broad incumbent comparable on modular leasing/rental model though concentrated in different geographies.
• WillScot: WillScot is the largest North American provider of mobile offices and modular space, operating a fleet and value-added products at significantly greater scale than Corner Cast. It competes in the broader modular space market though not in container-hybrid industrial construction specifically.
