Max-Rib II

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.

Max-Rib/Mesa with MoisureLok

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.

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.

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.
