Industries using powder coating that are considered to be Architectural include companies manufacturing metal doors, aluminum windows, metal siding, and other more structural items such as I-beams, basement jacks, and roof-truss hardware.
The list of applications above is varied, and so are the requirements for the powder that they use. For the exterior applications such as siding and windows, the powders used need to have top notch weatherability, along with adhesion. For the interior applications such as for I-beams and basement jacks, corrosion resistance and powder adhesion are prime considerations. There is a significant component of these industries that is controlled by Architects drawing specifications, with details covering both function but also color and finish.
