This project aims to build an efficient, durable, and fully functional prefabricated steel workshop for a client in Ontario, Canada. Measuring 80 feet long, 40 feet wide, and with a 22-foot eave height, the workshop’s design takes into account Ontario’s climate characteristics (such as winter snow loads) and utilizes advanced prefabrication techniques to ensure rapid construction, controlled quality, and long-term economic efficiency.
Detailed Design and Structural Description
1. Main Structure
Beams and Columns: The entire workshop’s structural skeleton is constructed from high-strength H-shaped steel. This steel shape provides excellent bending and compressive resistance while optimizing material utilization. Columns (H-shaped steel columns) serve as vertical supports and are rigidly connected to the H-shaped steel beams that form the horizontal framework, creating an extremely stable load-bearing system.
Extensive Column-Free Space: Through precise engineering calculations, a completely column-free interior space (40-foot spans) was achieved. This provides maximum flexibility for equipment layout, production line planning, and vehicle traffic flow, making it an ideal choice for industrial buildings.
2. Roof System
Gable Roof: The roof features a classic double-slope design with a central ridge. This design is not only traditionally beautiful but, more importantly, functional. It effectively and quickly channels rainwater and snow down the sides, significantly reducing the risk of roof loads during Ontario’s heavy snowfall.
Roofing Materials: The roof covering is constructed of high-strength metal panels. These panels are durable and corrosion-resistant, and they integrate seamlessly with the underlying purlin system to form a complete, waterproof, and robust roof system.
3. Enclosure System
Wall Panels: The exterior walls of the workshop are constructed of polyurethane sandwich panels. These panels consist of two metal panels with dense polyurethane foam injected between them. Their greatest advantage is their high thermal insulation value, effectively maintaining the workshop’s internal temperature, significantly reducing heating and cooling energy consumption during Ontario’s harsh winters and hot summers, and saving operating costs. Furthermore, they are quick to install and have a clean, attractive appearance.
4. Door and Window Systems
Rolling Doors: Large rolling doors are installed at the main entrance. This type of door saves space, opens easily, and provides excellent security, making it ideal for the daily operations of workshops and warehouses.
Plastic-Sealed Windows: The windows utilize plastic-sealed windows (usually with PVC frames). These windows offer excellent sealing properties, effectively preventing cold air infiltration and hot air loss. They also provide excellent sound insulation and weather resistance, making them a standard feature of energy-efficient buildings.
5. Interior Space Utilization
To maximize the 22-foot vertical space, a mezzanine structure was designed within the workshop. This mezzanine, typically composed of steel frames and steel panels, can be used for offices, storage, rest areas, or tool rooms, leaving valuable ground floor space fully dedicated to core production activities.
Project Advantages Summary
Fast Construction: All steel components were prefabricated in the factory and assembled on-site like building blocks, significantly shortening the construction period.
Durability: The steel structure and carefully selected materials resist deformation, corrosion, and adverse weather conditions, ensuring a long service life.
Economical and Efficient: Prefabrication reduces on-site labor and waste; excellent insulation performance reduces long-term energy costs.
Flexible and Compliant: The design fully considers Ontario building codes, particularly regarding structural loads (snow and wind) and energy conservation.
Overall, this 80×40-foot prefabricated steel workshop, with its H-beam main frame, double-slope metal roof, polyurethane sandwich panel walls, functional mezzanines, and efficient roll-up doors and plastic-enclosed windows, perfectly embodies a modern, high-performance industrial building solution tailored for clients in Ontario, Canada.
