Your Coating Choice Matters!
You’ll find two popular paint systems for metal roof and wall panels: Kynar 500® and Silicone Modified Polyester. The price point between the two on a residential project can be minimal, especially when considering the improved performance of the Kynar 500 system against fade and chalk.
Let’s look at a real-life example to showcase the difference. Both PVDF (Kynar 500) and Silicone-Modified Polyester (SMP) panels were installed on a home in Louisiana. On day one, the colors were an identical shade of green.
The accompanying photo, taken only eight years later, tells a powerful story of the differences between the paint systems as it highlights both the chalk and fade of the SMP paint system. Note that there is no visible fade or chalking on the darker (PVDF) panels.

Substrates Matter Too!
Underneath the paint/coating, the substrate of the actual metal is the heart of a metal roof panel.
You'll find two common substrates for metal panels: Galvanized and Galvalume®. Galvanized substrates feature a zinc coating applied to the raw steel, while Galvalume substrates feature an alloy of zinc plus aluminum.
Galvalume substrates offer homeowners the highest quality long-term solution.
Our recommendation is based on decades of research and actual field performance. Galvalume delivers better results, excellent corrosion resistance, and long-term aesthetics. Galvalume substrates also carry a warranty from Steel Mills against rupture or perforation due to corrosion. Similar Steel Mill warranties for Galvanized substrates simply don’t exist.

Ways We’re Different
We’re working hard to earn your business so multiple paint systems and substrate offerings aren’t the only things we do differently at McElroy Metal.
Check out the three additional options below that we offer specifically for our Post-Frame customers.
Thermoforming for the Win!
Thermoforming (or warm forming) is just another example of our commitment to customer satisfaction and constant improvement.
Traditionally steel panels have been manufactured from steel at room temperature. While that process worked for decades, new advances have proven that warming the steel prior to production can result in a better product with a longer life expectancy for Silicone Modified Polyester (SMP) paint systems.
Edge Rust Inhibitor
The cut ends of metal panels expose raw steel to Mother Nature’s elements, also resulting with the appearance of red rust. McElroy Metal provides factory applied edge coating to our Max-Rib and Mesa panels at our Post Frame manufacturing facilities*.
McElroy Metal’s edge coating processes applies a clear coat rust inhibitor at panel ends which helps to minimize corrosion.

Factory Applied Anti Condensation Fabric
Max-Rib roof panels with McElroy's MoistureLok, offer a great option to address condensation challenges. The design of our MoistureLok product traps moisture and then releases it back into the air as natural humidity once conditions go back below the dew point.

Choosing the Right Partner
Once you’ve decided on a post-frame building, it’s time to choose the right partners to make your dreams come true!
First, you want to select a reputable contractor who installs only high-quality building materials. If you’re exploring options, check out our Find-A-Contractor tool, which allows you to search for builders near you.
While selecting a great contractor is critical to your project’s success, it’s equally important to select a tier-one manufacturer for your metal roof and wall panels. While you might have a local manufacturer closer to you, there are tradeoffs for working with a regional manufacturer instead of a national one, like McElroy Metal.

Green Buildings and Solar Metal Roofing
Simply put, Green Building makes sense from both an environmental and economic standpoint. While reducing our carbon footprint has a societal benefit, individuals, companies and other entities benefit greatly, due to lower energy consumption and expense.
