Product Description
Product Overview
The 20×40×12 Steel Workshop Kit is a dependable, Canadian made workshop designed for customers who need a deeper and more spacious work area than a standard single-bay shop. This size offers room for tools, machinery, workbenches, storage racks, and project space all under one roof. Built with high strength Canadian steel, this workshop delivers reliable performance in real Canadian weather and requires minimal maintenance.
Manufactured in Barrie, Ontario, this building is engineered by our Canadian engineering team to meet the National Building Code of Canada and the snow and wind loads required for your location. Certified stamped structural and foundation drawings are included to support an efficient permitting process.
This size is often chosen by tradespeople, hobbyists, and rural property owners who need a well-organized, year round workspace.

Why This Size Works
With 40 feet of depth, this workshop provides ample space to separate work zones, store equipment, and maintain a clean, functional layout. The clear-span interior eliminates posts and keeps the entire floor open and easy to use. The 12 foot wall height supports tall shelving, larger machinery, and overhead equipment. This size is ideal for users who need extra depth to work efficiently.
Engineering and Durability
This building is engineered with Canadian steel for Canadian climates. The rigid frame provides long term structural strength, and the 26 gauge exterior panels protect against snow, rain, wind, UV exposure, and seasonal temperature changes. With insulation options up to R 60, this workshop can be comfortably heated and used year round.
Installation
All components arrive pre cut, pre punched, and labelled to make installation straightforward. Many customers hire a local contractor, while others assemble the workshop with a small crew. Installation and foundation support is available depending on your location.
