As of 2015, BIEC International produces Galvalume painted and unpainted corrugated standing seam roofing for structural and architectural applications. The structural roofing panels, which are constructed from 55 percent Aluminum-Zinc coated sheet steel, can be factory formed to any length up to 45 feet and can vary in width from 10 to 30 inches.
The structural panels can also be formed on the job site using portable rolls that are available in lengths up to 200 feet. The seams on the panels are generally 2 to 3 inches above the roof drainage surface, while the panel corrugation profiles are available in flat or trapezoid shapes. In structural applications, the sheets are normally fastened directly to the joist roof or purlin substructure.
Architectural Galvalume standing seam roofing panels normally have a flat panel profile and are available in widths ranging from 10 to 24 inches. These panels are generally shorter than Galvalume structural panels. They also have smaller seams, which are generally 3/4 to 2 inches above the roof surface. While unpainted roof panels are normally used for structural applications, architectural panels are generally painted and are available in a wide range of colors.
In addition to roofing, Galvalume coated sheet steel products can be used for siding applications, covering unexposed automotive parts and appliances. There are also many other possible miscellaneous applications, such as outdoor cabinetry, furniture, gutters, computer cases and piping.
