You don’t promise 40 years of protection unless you can back it up.
At MBMI Metal Buildings, that confidence isn’t just marketing. It’s engineered into every panel we produce. For decades, our customers have trusted that their buildings will stand strong, resist rust, and keep their color, even after years of blazing sun and brutal weather.
So what’s the secret behind that kind of staying power?
The answer lies in a carefully layered process that combines metallurgical science with high-performance finishes and an unwavering focus on quality.
Every long-lasting panel begins with the right foundation. At our metal building company, that foundation is Galvalume®, a steel substrate coated in a precise mixture of 55% aluminum and 45% zinc.
The aluminum acts as a barrier, shielding the steel from environmental exposure, while the zinc provides sacrificial protection. That means even if the surface is scratched or damaged, the surrounding zinc will corrode first, essentially “taking the hit” to keep rust from spreading.
It’s a smart, self-preserving system. And it’s one of the biggest reasons our high-gloss panels continue performing after decades in the field.
Of course, structure is only part of the story. What really sets MBMI panels apart is what you see and what you don’t.
Our high-gloss paint systems don’t just offer aesthetic appeal. They’re built for performance, using PVDF (polyvinylidene fluoride) coatings that are renowned in the metal building industry for one thing: endurance.
These finishes use ceramic-based pigments that are chemically stable and highly resistant to UV breakdown. That means less fading, less surface wear, and more visual integrity over time.
We’re not talking about a few extra years. We’re talking about decades of color stability, even in areas with intense sun exposure.
One of the most frustrating signs of aging panels is chalking. That dusty white residue that builds up over time and dulls the look of a building. It happens when resins break down under UV light and moisture, leaving powdery particles on the surface.
To combat this, MBMI’s coatings include high-grade resins specifically selected for their chalking resistance. These resins stay strong, maintaining both the finish and the clean, professional appearance our customers expect.
The result? A building that still looks sharp when your neighbor’s panels have already started to show their age.
Durability at MBMI doesn’t stop with paint and metal.
Our panel system includes premium lifetime fasteners. A detail many overlook. These fasteners match the finish of the panels and are made to resist rust, which is critical for protecting structural integrity. Cheaper fasteners might save a few dollars up front, but they often void warranties and become the first point of failure.
We also engineer every building to meet local codes and regional demands, from coastal environments to snowy mountain towns. Our base and eave trim, larger base angles, and cable bracing aren’t just for looks. They improve stability, prevent sagging, and simplify assembly.
In short, it’s a complete system, backed by engineering experience and built with longevity in mind.
Our 40-year panel warranty isn’t a formality. It’s a reflection of how confident we are in our materials, coatings, and process. When customers ask how long their building will last, we don’t hesitate.
And that kind of peace of mind? It’s engineered into every square foot.
There’s a reason customers come back to MBMI when it’s time for their next project. The shine doesn’t fade. The panels don’t chalk. The structure stays sound.
Because when you invest in a building, you’re investing in the future. And we’re proud to build panels that are still performing strong 40 years later.
