In addition to frame, wall, and roof systems, there are other components of a metal building system generally referred to as accessories. These include roof vents, light transmitting panels, interior liner panels, louvers, wall lights, wall openings, windows, pedestrian doors, overhead doors, fascias, mansards, canopies, and trim in general. Any numbers of these items are required to complete a metal building system. These individual components are also manufactured as integral units for the metal building system. When installed, they will be compatible in both design and appearance with the wall and roof systems that they penetrate.
A roof vent is defined as an accessory, used on the roof that allows the air to pass through. Gravity ridge roof ventilators are manufactured from Galvalume® steel, and may be painted white. The ventilator body is made of 26 gauge steel and the skirt matches the roof slope. Chain operated dampers are furnished when specified. Standard operators include cable, pulleys, cable clamps, and eyebolts. Three continuous vents may be operated from each operator. Each non-continuous vent requires an operator.
Ventilators are equipped with standard bird screens and riveted end caps. Ridge ventilators are 10' long and have 12" throat. Ultra-vents are 1'-11" long with a 12" throat. 20" and 24" round ventilators are also available.
A "light transmitting panel" is a plastic roof panel installed to admit light. The acrylic modified, UV stabilized, light transmitting panels are high strength translucent panels that are made of glass fiber reinforced polyester. The high strength translucent panels match standard panel profiles, are 1/16" thick, weigh 8 ounces per square foot, and are white with a granitized top surface. Insulated light transmitting panels are also available.
Light transmitting panels are installed using the same procedures as a steel panel. Care should be taken when installing fasteners in the light transmitting panels to avoid cracking the material. Pre-drill 1/4" diameter fastener clearance holes in the overlapping sidelap and endlap.
Do not under any circumstance step or walk on surface of light transmitting panel. If foot traffic is necessary over light transmitting panel, use walk boards that are properly supported by building purlins.
Louvers are an opening provided with fixed or adjustable slanted fins to allow for the flow of air. The Manufacturer's louver frames are of 18 gauge galvanized steel frame, painted to match the wall color with 20 gauge blades, and are self-framing and self-flashing. The louvers can come with fixed or adjustable blades. Standard sizes are as follows:
Windows are openings in the wall of a building for the admission of light and air. The standard windows available through SBS are horizontal slide units; with a mill standard finish with bronze painted finish as an available option. The windows are furnished with complete hardware, half screen, and the glass is available in a clear or bronze tint. The windows are self-framing and self-flashing to the wall panels. The windows are certified by Architectural Aluminum Manufacturers Association for the performance requirements of ANSI/AAMA. The aluminum horizontal slide windows are available in the following sizes:
A fixed 2' 0" x 7' 0" slim line window is also available. This narrow, fixed window is perfect for an office environment to admit natural light.
Walk doors are doors used by personnel for access to and exit from a building. Standard personnel doors are manufactured from 20 gauge galvanized steel with an embossed finish in white or bronze prime coat. The doors are flush and have vertical mechanical interlocking seams, which join both hinge and lock edges. The doors are provided with top and bottom inverted 16 gauge galvanized steel channels spot-welded within the door. The door is reinforced, stiffened, and sound deadened with impregnated kraft honey comb core completely filling the inside faces of the door and laminated to the inside faces of the panels. All doors are available with applicable hardware, such as panic hardware, mortice lockset, standard lever lockset, weather strip, closures, or keyed alike. The doors can be all metal, half glass, or narrow lite and available in sizes, 3' 0" x 7' 0", 4' 0" x 7' 0", or 6' 0" x 7' 0" (2 - 3 x 7 leaves, with one or both active). Glazing is by others.
The doorframes are of 16 gauge galvanized steel, pre-painted white with 8" standard jamb depth and constructed for non-hand installation. The frames are provided with head and jamb flashing, optional weather strip, 1 1/2" pair of 4 1/2" x 4 1/2" hinges, and reversible strike plate.
The threshold of the door is aluminum and supplied with flat head screws and expansion shields for attachment to a masonry floor.
Framed openings consist of framing members and flashing which surround an opening for accessories such as windows, louvers, fans, and roll up doors. Overhead door framing is designed to resist applicable wind loads and consists of channel jambs with a structural header at the top of the opening. 26 gauge galvanized steel flashings, color coordinated with wall color is provided to conceal panel edges around the opening.
We offers a wide range of wall panels for use on a metal building; see the section on wall systems. However, many good reasons exist for using other types of materials in combination with metal panels or by themselves. When a metal building is opened for collateral material it is considered an open wall condition. A few common collateral materials are masonry, glass, wood, and concrete or any combination of these.
