PANEL OPTIONS
Color or GALVALUME®. Our online design and pricing system gives you two panel options – SMP Colors and GALVALUME PLUS®. Our standard colored panels consist of GALVALUME PLUS® sheets that have been prime-coated with SMP paint. Both panel types are tough and come with warranties – 25 years for GALVALUME® sheets and 30 years for colored sheets. You might want to consider colored panels for your roof. The GALVALUME PLUS® panels are less expensive, but the colored panels give your steel a more sophisticated look.
Color and Roof Pitch. The roof pitch of your steel building can help you decide the type of panels, color or GALVALUME PLUS®, for your roof. Colored panels are appropriate for high-pitched roofs, which are more noticeable. Choose GALVALUME PLUS® sheets if your steel building has a low-pitched roof, which can barely be seen.
Skylights. We offer high quality skylights, one of the most popular panel options available for steel buildings. These are translucent panels that allow natural light to come inside the building. Placing an adequate number of these translucent panels will provide enough illumination during the day, allowing you to save on energy costs. Placing two skylights per bay, is the standard configuration.
BASE CONDITION
A steel building’s lateral member that runs the entire perimeter of the building or near its base is called its “base condition”. This girt provides the lower anchor for the wall panels and determines exactly they relate to the foundation. In order to prevent water and pests from entering the building at its base, a portion of the panels must extend below the outside of the concrete slab.
To accomplish this, we offer a variety of approaches depending on the your situation. If your steel building has a concrete slab foundation, we recommend the first three options – base angle, base trim, and deluxe base trim. However, for special conditions, we propose that the remaining options – base girt, base channel, and base channel with trim, be used.
Base Angle. Unless otherwise specified, the default base condition is the standard base condition. It is part of the base cost of any steel building you design online. This approach requires that the slab be formed with a 1 ½” sheet notch to allow the sheets to extend below the top of the slab. Then, a single angle member is attached with exposed fasteners to both the wall sheets and the slab. Note that his approach has several disadvantages when compared to the other options. First, since the wall panels are in direct contact with the concrete, which may cause a chemical reaction, the sheets may eventually be lose their color. Also, the approach may cost more considering that you have to extend the concrete slab for 1 ½” more.
Base Trim. The only difference between a base angle and a base trim is the added trim piece. This extra trim acts as a barrier against pests and prevents the sheets from coming in contact with the slab. It comes in all standard trim colors.
Deluxe Base Trim. We recommend this approach for steel building construction with concrete slab foundations. It combines the trim and base angle into one piece, providing the benefits of the base trim approach and at the same time concealing the wall fastener. It is only available in neutral color burnished slate.
Base Girt (liner ready). This option is designed for steel buildings that sit on piers rather than a full concrete slab. A base girt system, unlike other base options, is not attached directly to the foundation. Instead, the base girt is attached to clips on the columns about 6” above the foundation. It also provides a connection for liner panels.
Base Channel.(liner ready). The base channel approach consists of a “C” section that covers the entire perimeter of the building flush with the floor. The “C” section provides a fixed connection point for inside panels. The base channel requires a sheet notch in the slab and is commonly used when liner panels are going to be installed.
Base Trim and Base Channel. This approach combines the solutions provide by the two options. The base trim removes the need for a sheet notch in the slab. There is no more need to extend the slab an extra 1 ½” below the frame line. In addition, the base channel provides the connection for the liner panels.
TRIM AND GUTTER
The trim used on a steel building has two functions. Aside from the fact that it seals a specific transition point where building components are joined together, it also has an aesthetic function. Trims provide steel buildings a more polished and professional finish. Providing protection from the elements is the more important function. Trims prevent water and air from entering the small gaps at transition points. Water can damage the building and its contents while air makes your steel building’s insulation less effective.
Trim covers the corners and edges of your steel building. For instance, an eave trim is used to create a transition from the roof to the sidewalls while a rake trim joins the end walls to the roof.
Our premium-quality trim packages do not contain generic pieces. They are engineered and tailor-made to specifically match the dimensions of your steel building, guaranteeing a secure fit. All exposed edges of the trim are hemmed to create a smooth finish and to ensure easy and effortless installation - saving you headaches created from delayed construction and additional labor costs.
Jamb Cover Trim. This is an inexpensive way of improving the appearance of your steel building. The jamb cover trim provides protection and cover to the red-iron jamb and header around a framed opening.
Gutters and Downspouts. These optional accessories also serve as trim. Aside from this function, they control the runoff of snow and water from the roof. Gutters and downspouts also enhance the appearance of your building, aside from preventing water from splashing on the sides.
Ridge Caps. Die-formed ridge caps are used to cover the peak of the steel building opening, connecting the panels on either side. Compared to ridge rolls, which must be bent into place and must be sealed with closures, die-formed ridge caps are easy to install. They are designed to perfectly match the panel profile and roof pitch of your steel building. What’s more, aside from creating a seamless transition across the roof, they also seal it against leaks and pests.
