Clear-span, multi-span & lean-to frame systems
Straight Wall Buildings:
Frame Styles
Straight wall buildings offer several frame configurations, each suited to different space and cost requirements: clear-span frames for a fully unobstructed interior, multi-span frames with interior bearings for cost efficiency at wider spans, and lean-to frames for expanding an existing structure.
Two structural steel building types
Cold-Formed vs. Red Iron: Straight-Wall Steel Building Framing
Cold-Formed Steel Framing
Cold-formed steel buildings use lightweight, shaped steel components, including C-channel framing, to create a versatile structure for garages, workshops and storage buildings. Bolted connections and lighter components can simplify handling and assembly, making smaller kits a practical option for DIY owners or local contractors. Toro custom-engineers each building for its intended use and location’s applicable loads and codes.
Red Iron Steel Framing
Red iron steel buildings use substantial structural steel I-beams to accommodate larger spans, taller building heights and demanding commercial or industrial applications. This framing system is well suited to warehouses, manufacturing facilities and large agricultural buildings, with options for expansive clear-span interiors. Where specified, the structure can also be engineered to support mezzanines or overhead cranes. Toro designs the building around your operational needs and local loads and codes, with assembly typically handled by a local contractor.

Frame family 02
Multi-Span Frames
Best when unobstructed space isn’t required and an interior bearing is feasible.
Multi-span option
Long Bay
An open web truss subframe supports the roof and makes mechanical and electrical runs easier to install.
Unobstructed interior
Up to 65′
Frame family 03
Lean-To Frames
Used to expand or extend an existing structure, such as adding an office or storage area. A lean-to must be supported by attaching to the existing frame.

Questions
Yes, mobile and portable building options are available for temporary site needs.
Common accessories include overhead doors, insulation systems, skylights, ventilation systems, mezzanines, interior partitions, and security features.
Vents improve airflow and temperature control, reducing condensation and maintaining air quality. Skylights provide natural daylight, lowering energy consumption and improving interior visibility. These accessories enhance building comfort and operational efficiency.
Straight wall steel buildings can be engineered for wide clear spans. Cold formed models are typically suited for smaller widths, while red iron buildings can exceed 50 feet in width and support large open interiors without interior columns.
Steel storage buildings can be customized with doors, windows, ventilation and interior layouts to suit what you're storing. Insulation is available as an option and isn't included in the kit.
