| PAINT SYSTEMS:
Kynar 500 - The PVDG (Fluorocarbon) paint system combines ceramic pigmentation with polyvinylidene florid for a superior, long-lasting performance. (Usually guaranteed for a minimum of 20 years) PVF2 finishes are respected for their durability residence, and color retention. PVF2 finished meet both Kynar 500 and Hylar 5000 specifications; Kynar and Hylar are produced under license from Alf Atochem North America, Inc. and Ausimont, respectively. Acrylic: - Polyester-based paints are synthetic polymers which have a durable, abrasion-resistant surface. Generally these come with a three to five year warranty. A variation of this product comes with a siliconized polyester blend that provides a good chalk resistance and gloss retention. Siliconized polyesters generally come with a 10 to 20 year warranty. Galvanized - Zinc Coating - commonly found in steel which relies on a chemical reaction of zinc, which slowly melts away while protecting the underlying metal. The thicker the coating the better the protection. The coating conforms to ASTM standard A-653 with a G60 or G90 designation which is adequate for most roofing applications.Galvanized - Zinc Coating - commonly found in steel which relies on a chemical reaction of zinc, which slowly melts away while protecting the underlying metal. The thicker the coating the better the protection. The coating conforms to ASTM standard A-653 with a G60 or G90 designation which is adequate for most roofing applications. Aluminum Coating - the difference between aluminum and zinc is that the aluminum acts as a physical barrier formed by aluminum oxidation process. ASTM A-463 requires that the metal be coated with aluminum at 0.65 ounces per square foot on both sides. Galvalume: Aluminum-Zinc - Combine the chemical action of zinc and the barrier protection of aluminum. Galvalume was developed by the Bethlehem Steel Corp. and is described in ASTM A-792. This make-up is 55 percent aluminum and 43.5 percent zinc and 1.5 percent silicone. This product also goes by the name of Zincalume which is a registered trademark of BPI Steel. Bonderized Steel: For those looking for a premium bonding surface for post painting applications, zinc phosphate pretreatment provides the perfect surface for field painting of flashings, gutters, downspouts and other roofing materials. In a continuous, controlled process, coils of galvanized steel are first thoroughly cleaned and rinsed. A conditioning agent is then applied to promote the formation of a fine crystalline zinc phosphate coating. This process then converts the bare galvanized surface to an inert, crystalline zinc phosphate which is subsequently rinsed and sealed with a dried-in-place chromate conversion coating. This entire process creates what we would call a Bonderized surface. Careful measurement and control of coating weight results in a crystalline coating that bonds with the galvanized substrate and creates a micro porous surface for exceptional adherence of the paint film. This non-conducting zinc phosphate layer provides a diffusion barrier against the penetration of water and oxygen along with additional chemical resistance. It all adds up to a surface that promotes adhesion and works to reduce potential corrosion underneath paint coatings. This product is produced by Ispat Sidbec Inc. and by other various steel mills around the world under the trade names of Corten, Kupten, Triacor, and others. It is a high strength cold rolled steel of architectural interest because after installation and exposure to normal weather the surface, in place, develops a pleasing iron oxide matte finish, which accents the appearance of any building on which it is use. The weathering process that occurs after installation eventually decreases and from that point on the finish acts as a protective coating for the base metal. Like many other architectural products with desirable features, some cautions must be exercised during installation. The roofing sheets are simple to install using the same methods as any other metal roofing sheets. However, care must be taken that the roof drains well so that no residual moisture can be trapped between two or more overlapping sheets. If moisture is trapped, the weathering process may continue where the moisture is trapped and the reaction will not stabilize as planned. The runoff of moisture from these panels will badly stain concrete or stucco. Be careful where the run-off is directed to prevent staining. Also, the fasteners used, either nails or screws, should be of non-plated stainless steel, anodized aluminum, copper, bronze or brass. Zinc and cadmium coated items are not suitable for use in contact with Corten Steel. |
