Metal Building Accessories
Metal building accessories are the doors, windows, vents and roof fittings that turn a steel shell into a finished, working building. Universal Steel designs and prices these accessories as part of your building system, to the nearest 1/16 of an inch and to meet most common building codes. Each one is engineered by experienced engineers to exacting tolerances, so the openings, penetrations and fittings are detailed into the frame rather than worked out on site.

Accessories are easy to treat as an afterthought, but on an engineered metal building they are part of the design. When you order a building from Universal Steel, the doors, vents, flashings and curbs are specified alongside the frame, the wall panels and the roof, so every opening is framed for, every roof penetration is detailed, and every fitting arrives ready to go in. That is the difference between accessories engineered into a building and parts bought loose and made to fit afterwards.
Our accessories fall into three groups. Doors and windows cover the openings people and light move through, from galvanized walk doors to fast-install glass doors. Ventilation covers the fittings that move air and exhaust, from continuous ridge vents to roof jacks for duct and fan pipes. And roof penetrations and equipment accessories cover everything that has to pass through or sit on the roof cleanly and without leaking, from pipe flashes to custom curbs for roof-mounted equipment.
Because these are engineered with the building, the cleanest result comes from specifying them up front. Tell us how the building will be used and we will work the right accessories into the design and the quote.
Our accessories
Steel Doors & Windows
The openings for access and light, engineered into the wall framing. Our walk doors use a galvanized 16-gauge frame with embossed door leaves, bonderized and finished with a coat of bronze primer. Our full-glass PDL doors are built for fast installation: you uncrate, set in place, plumb and square, then anchor. And our thermal-efficient windows are energy-rated units that limit heat transfer, framed into the wall line to suit the building.
Walk doors: galvanized 16-gauge frame, embossed leaves, bronze primer; Full-glass PDL doors: pre-built for fast set-and-anchor install; Thermal-efficient windows: energy-rated, framed to suit
Ventilation
The fittings that move air and exhaust through the roof. Our ridge vents, or Univents, are gravity-type units, 10 feet long with a 9-inch or 12-inch throat in 26-gauge steel, available with or without dampers and designed for continuous runs along the ridge. Our monovents are gravity ventilators mounted at the building's peak, where natural air movement gives consistent ventilation throughout the interior; they are typically 20 inches, circular, 26-gauge, and fitted with dampers to regulate airflow. Roof jacks are mountable DuraRib fittings that shield venting duct pipe from attic ventilation and from bath and kitchen fans, sized to hold shingle stacks between 7 and 12 inches.
Ridge vents (Univents): gravity-type, 10ft long, 9" or 12" throat, 26-gauge, optional dampers, continuous runs; Monovents: gravity, peak-mounted, ~20" circular, 26-gauge, with dampers; Roof jacks: DuraRib, shingle stacks 7" to 12"
Roof Penetrations & Equipment Accessories
The fittings that let pipes, vents and equipment pass through or sit on the roof and walls cleanly and without leaks. Our pipe flashes are flexible pieces that make flashing pipes cleaner, easier and more efficient, fitting pipe diameters anywhere from 1/4 inch to 7 inches. Access curbs are custom-built to accommodate roof-mounted equipment. Louvers are adjustable-blade vents set into the wall to control through-wall airflow.
Pipe flashes: flexible, fit 1/4" to 7" pipe diameters; Access curbs: custom-built for roof-mounted equipment; Louvers: adjustable-blade wall vents

Metal Building Accessories questions
What accessories come with a metal building?
Universal Steel offers the full range of fittings that finish a steel building: walk doors and full-glass doors, windows, ridge vents and monovents for ventilation, roof jacks for duct and fan pipes, pipe flashes for clean roof penetrations, louvers for through-wall airflow, and custom curbs for roof-mounted equipment. Which you need depends on how the building will be used, and we will recommend the right set as part of your design.
Are accessories engineered into the building?
Yes. When you order from Universal Steel, the doors, vents, flashings and curbs are specified alongside the frame, walls and roof and engineered to the nearest 1/16 of an inch. That means every opening is framed for and every roof penetration is detailed in the design, so the parts arrive ready to install rather than being cut and fitted on site.
Can I add accessories to my building later?
Some accessories can be added after the fact, but the cleanest, most weather-tight result comes from engineering them into the building from the start, when openings can be framed and penetrations detailed as part of the design. If you are weighing up what to include, tell us how you will use the building and we will work the right accessories into the quote.
