Unlimited applications
Roofs, fasciae and soffits: The superior appearance and performance of today's standing seam metal roof -- now more widely specified than any other metal roof type -- has resulted in a resurgence of interest among architects and owners to make the roof visible. Roofs have become part of the architecture and are no longer just an element to keep out water. Metal roofing systems, produced from prepainted Galvalume sheet, offer great potential for the use of roof colors that complement the color of the other architectural elements. A wide variety of roof panel widths and seam effects can be achieved. Both high- and low-standing seams are available.
Designers should become familiar with and work within the modular dimensions of the particular standing seam roof system being specified. Through-roof penetrations for skylights, hatches and other features should be laid out to fall between -- not directly on -- seams. Overall building geometry and dimensions should relate to the pattern and interval of roof seams.
Claddings, sidings and spandrels: For curtain-wall, cladding and siding applications, large facade areas can be covered with the confidence that panel appearances and desired architectural effects will be uniform over the entire area of application. Because the quality of factory-controlled paint applications cannot be matched in the field, the use of prepainted Galvalume sheet panels helps to assure that color rendition and panel appearance will be uniform throughout the project.
Flexibility in color choice also provides greater opportunity for the selective use of metal on facades, in combination with masonry, concrete, wood and other materials. For projects that combine other exterior finishes and materials with metal, the availability of such materials as prepainted Galvalume sheet minimizes difficulty in matching or complementing desired colors.
Mansards and canopies: Many architectural exterior building elements can be designed and produced from the same prepainted Galvalume sheet steel used for the building roof and envelope.
Economies of scale can be achieved by integrating the overall building design approach, and assuring that each exterior architectural element complements and works with all others. The materials used to create canopies, mansards, sculptural fasciae and other special architectural forms can be provided by the same suppliers who install systems and components for roofing and exterior walls. Also, installation can be done by the same crews using similar equipment, minimizing jobsite complexity and construction delays.
Prepainted Galvalume sheet, used for such applications, helps assure superior performance and appearance, not just in the crucial building envelope, but throughout the project. The main elements and details can be designed to function as parts of a total architectural system.
Copings, rake edges, gravel stops and trim: Frequently, a project designer's work is allowed to end once the basic design approach has been established; the rest is left to detailers. But fulfillment of an overall design concept often lies in the successful execution of the details. Here, too, prepainted Galvalume sheet can offer special design advantages.
All of the "little elements" -- trimwork, stops, copings and others -- which are critical to accomplishing the overall design effect, can be executed using the same materials, treatments and colors that are used for coverage of larger exterior areas. The technical problems of transitions, seaming and joinery are minimized by using identical materials. Of equal importance, designers can be certain that awkward, unsightly or technically inappropriate details won't spoil a project's appearance or undermine design intent.
