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 16 inchwidths and in colors that match McElroy's wall and roof panels.
