Galvalume® substrate with Kynar 500® coating
For unsurpassed performance in a light gauge panel, Max-Rib Ultra is the ultimate choice. Max-Rib Ultra combines the long-life performance of a Galvalume steel substrate with a fade and chalk resistant Kynar 500® (PVDF) based Fluropon® paint by Sherwin Williams. The end result is an exceptional metal panel that provides unmatched resistance to chalk and fade and the best assurance that your project will retain its beauty year-after-year. Max-Rib Ultra is the preferred panel for any building where owners are concerned about quality and long-term performance.
Galvalume substrate with a Silicone Modified Polyester (SMP) coating
Combining the long-life characteristics of a Galvalume steel substrate with the proven performance of a high-quality Silicone Modified Polyester (SMP) coating, Max-Rib II is an excellent multi-use metal panel. McElroy Metal’s SMP coating is WeatherXL by Sherwin Williams. This coating would be classified in the “good” category, so it will not perform to the same level as the Sherwin Williams PVDF coating, Fluropon.
Galvanized G100 substrate with a Silicone Modified Polyester (SMP) coating
Combining a zinc-coated G100 Galvanized substrate with a high-quality Silicone Modified Polyester coating, Max-Rib 100 is an ideal panel when a Galvanized substrate is required.
Max-Rib Commodity is a 10-year warrantied economical panel that is ideal for interior applications such as liner panels or basic shade and shelter projects.
Many post frame panels look identical from manufacturer to manufacturer. Mesa is a patent and copyright protected panel that can't be copied and features a nearly invisible lap offering a distinctive look.
Mesa's standard paint system is Kynar 500® (PVDF), the industry's best coating for long-term protection against panel chalk and fade.
When temperature and humidity conditions reach the dew point, moisture can condense on the underside of metal panels and form droplets of water. MoistureLok anti-condensation membrane can be factory applied to Max-Rib and Mesa panels. The MoistureLok membrane traps condensation until environmental conditions go back below the dew point and moisture is simply released in the form of normal humidity.
Matrix soffit panels add an elegant touch to any post frame project. Matrix is available in 12 and
Metal roofing and siding have many levels of quality. When choosing your materials, you'll want to be sure they will meet long-term performance expectations.
To that end, McElroy’s popular Max-Rib panel is available with different substrates and coating combinations. The accompanying chart will help you match product performance with your needs.
Trim, or flashing, is installed at the intersections and terminations of metal wall and roof panels to seal the building and prevent water from entering.
Trim is available in the same variety of colors as McElroy's wall and roof panels, so you can match the wall panel color or choose complementary or contrasting colors. McElroy also fabricates custom trims to match the specifications and design preferences of our post frame builder customers.
McElroy Metal sells a variety of accessories to complete a post frame building, including fasteners, caulks and sealants, closures, and snow retention products. Many of our service centers also carry tools, insulation, cupolas, and more to support post frame customers.

Work with your contractor to ensure quality materials are installed on your project, and always ask what substrate and coating they are proposing. If they don't know or say that their SMP is almost as good as a PVDF coating, that could be a red flag.
