Steel has several real advantages over other construction materials, but customizability is arguably its biggest strength — a single structural shell can be configured dozens of different ways without compromising the building’s core durability. Here are the customization categories Toro offers across every steel building.

Wall Accessories
Wall customization comes in the form of commercial doors and translucent light-transmitting panels. Choose from a complete line of commercial doors — self-storage doors, steel curtain roll-up doors, and pre-assembled steel man doors — in different sizes, styles, and colors, with custom sizes, gauges, and hardware available on request. Translucent light-transmitting panels, made from fiberglass-reinforced plastic, let natural light into the space without a traditional window.
Roof Accessories
Roofing customization covers a genuine range of options: a circular gravity-type ventilator (mono-vent) with damper for general ventilation, metal roof jacks mounted on roof panels for stack sizes up to 12 inches, and univents — ventilator units with or without dampers, suited to continuous runs. Curbs are available in standard or custom sizes, matched to your roof pitch, and translucent light-transmitting panels can be added to the roof as well as the walls for additional energy savings.
Trim and Flashing
- Corner Trims: Cover joints between panels at building corners.
- Eave Trims: Cover joints between sidewall panels and roof panels.
- Gable Trims: Close joints between roof panels and end-wall panels on gable roofs.
- Window Trims: Cover joints between window frames and wall paneling.
- Framed Opening Trims: Finish off doors and other framed openings.
- Base Trims: Close off the lower edges of wall paneling.
- Gutters and Downspouts: Collect and direct precipitation away from the structure.
Frame Configuration
- Clear-Span Frames: For structures where the interior space must stay unobstructed — a good choice for aircraft hangars, equestrian arenas, offices, and ice arenas.
- Multi-Span Frames: Used where an interior bearing point is practical; once a span exceeds 100 feet, an interior bearing becomes important for the structure’s safety.
- Lean-To Frames: Built primarily to expand or extend an existing structure with additional space.
Choosing between these comes down to how the interior will actually be used. If your project genuinely needs unobstructed floor space — vehicles maneuvering, livestock movement, sports activity — clear-span is worth the added engineering even past 100 feet where practical. If the space is primarily storage or doesn’t require that open floor plan, a multi-span frame can be more economical once the span gets large. Lean-to frames are less a standalone choice than a planning consideration: if you already know you’ll want to expand later, discussing that with your Building Specialist upfront makes the eventual addition far simpler than retrofitting an unplanned expansion.
Insulation
Insulation is used across garages, stores, barns, grain sheds, warehouses, and hangars to control condensation, manage noise, and reduce energy costs. Toro uses high-quality fiberglass insulation, customized to your specific needs for comfortable working, storage, or living conditions.
Why Customization Doesn’t Compromise Durability
Every one of these options is engineered into the building’s design from the start, not bolted on as an afterthought — the same structural strength that resists high winds, snow loads, and seismic activity holds regardless of which doors, trim, or frame configuration you choose. That’s the real advantage of steel’s customizability: you’re not trading durability for design flexibility, you’re getting both at once.
Permits, Codes & Engineering
Whatever configuration you choose, Toro’s in-house engineering team calculates your building’s design loads for its specific address, following the ASCE 7 standard from the American Society of Civil Engineers or the National Building Code of Canada, before it ships.
