Union’s products are available in several grades designed to suit your desired level of performance. Our premium grades are Metal Construction Association (MCA) certified for use on residential and light commercial applications. The MCA set industry guidelines for quality and durability in response to problems with manufacturers selling substandard products that performed poorly over time. Union is one of only a handful of manufacturers that offer certified steel metal roofing systems. See the MCA’s website at www.metalconstruction.org for more information.Our 300 and 500 series steel metal roofing systems use high strength steel that’s protected by an aluminum, zinc, and silicon anti-corrosion coating, commercially known as Galvalume®. The corrosion resistance of our steel metal roofing system is so outstanding, even our unpainted Galvalume® panels carry a 25 year limited warranty. On top of our premium base metals, we offer several state-of-the-art multi-layer paint systems that offer years of fade and chalk resistance. Below you’ll find descriptions for our various steel metal roofing systems.
