Galvalume® substrate with Kynar 500® coating
For unsurpassed performance, Max-Rib Ultra is the ultimate choice. Max-Rib Ultra combines the long-life performance of a Galvalume substrate with a fade and chalk-resistant Kynar 500® (PVDF) based Fluropon® paint by Sherwin Williams. 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 with a high-quality Silicone Modified Polyester (SMP) coating, Max-Rib II is an excellent multi-use metal panel. While a good product, this coating will not perform at the same level as the Kynar 500® (PVDF) based Fluropon®, used for our Max-Rib Ultra offering.
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.

Quality Materials = Long-term Customer Satisfaction
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.

Post Frame Trim Details
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.
Post Frame Accessories
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.

Tips for Building Owners
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.

Superior Manufacturing Processes
Our warm forming process reduces the cracks in paint and coating that occur during the typical metal panel manufacturing process.

Factory-Applied Rust Inhibitor
Our factory-applied edge coating process applies a clear coat rust inhibitor at panel ends.

Superior Coating for Long Service Life
We coat our Max-Rib Ultra panels with a Kynar 500-based PVDF coating to ensure a long service life with high resistance to fade and chalk.
