Continous Coil
Coating Process
Coil coatings are applied to coil-formed metal sheets by a continuous, automated process that can happen at up to 700 feet per minute. Coil is unwound, cleaned, treated, primed, painted and baked before being recoiled for shipment.
Extrusion
Coating Process
Extrusion coatings are applied in a manufacturing process on a vertical or horizontal line that consists of cleaning and pretreating aluminum preformed extrusions, through a spray process, and then thermally curing the coating to set the system.

Resins & Pigments
Resins bind together all the components of a paint formulation, serving as the source for durability and physical properties. Resins increase the physical strength and chemical resistance of coating film, and allow the curing process to occur while paint is drying.
Pigments provide color and function to coatings. Organic pigments are natural and very bright in appearance, but have a low resistance to fading and poor weathering ability. Inorganic, or ceramic, pigments are made of metal oxides and mixed metal oxides that have higher resistance to fading and excellent weathering ability.
Coating performance
Exposure to the sun (UV light), moisture and humidity, high temperatures and temperature fluctuations can lead to color changes, chalking, blistering, corrosion and many other physical factors to the protective metal coating.
TEST, TEST AND TEST AGAIN
Weather testing includes both long-term, natural exterior weather exposure and laboratory-accelerated weathering. The testing and evaluation conducted by Sherwin-Williams technical experts meets all appropriate industry association standards and verifies performance, application, weathering and appearance of sample panels.
Natural Exposure
Testing Process
Exterior weather exposure (natural weathering) involves placing sample panels on inclined open racks orientated at the sun, usually at a 45 degree angle in a southerly direction. This angle ensures full UV exposure.
Accelerated Testing
Testing Process
Special environmental cabinets and instruments are used to speed up the weathering process and measure its effects under extreme conditions.
What is ASTM?
ASTM International, formerly known as the American Society for Testing and Materials (ASTM), is a globally recognized leader in the development and delivery of international voluntary consensus standards. ASTM standards help level the playing field so that businesses of all sizes can better compete in the global economy. **www.astm.org
What is AAMA?
American Architectural Manufacturers Association (AAMA) stands as a strong advocate for manufacturers and professionals in the fenestration industry and dedicated to the promotion of quality window, door, curtain wall, storefront and skylight products. They work to improve product, material and component performance standards. **www.aamanet.org
Other Associations
We’re in good company when it comes to our Green Agenda, and we’ve demonstrated our commitment to sustainability through memberships in Energy Star, USGBC (U.S. Green Building Council) and LEED and CRRC (Cool Roof Rating Council).
Chalking
Chalking is caused by degradation of the resin system at the surface of the finish, usually due to exposure to ultraviolet (UV) rays. As the resin system breaks down, resin particles take on a white appearance and imbedded pigment particles lose their adhesion to the film
Gloss Retention
Gloss is defined as the ability to reflect without any scattering of light. Direct UV exposure can degrade the top coat luster.
Fading
Fading is caused by UV and hydrolytic degradation of the resin system. If organic pigments are present in the color, they may also be degraded. Fading is calculated using Delta (dE) values – a single number that represents the distance between two colors.
