Exposed Fastener Panel Products

Max-Rib is a low profile (3/4") panel that is very popular with homeowners across the country due to its aesthetic appeal and price point. This panel profile is also very common in the industry and many manufacturers offer this panel in a wide variety of steel substrates and coatings. Homeowners should make sure the product being installed on their home matches their long-term performance criteria. For residential applications, McElroy strongly recommends a Galvalume steel substrate with Kynar 500^® (PVDF) coatings, which offer optimal performance and protection against fade and chalk.
