What is Strongpanel?

Strongpanel applies thicker galvanized zinc coating to the panel to help it resist rust better. Many competitive panels save costs by using less zinc. More zinc means more protections against rust. It's that simple.

Here's how it works. The steel is run through a bath of molten zinc. The zinc chemically bonds to the steel, so there's a layer of zinc between the steel and the air. Before the steel can rust, the zinc "sacrifices" itself, slowly oxidizing while protecting the steel. The result? A panel that can stand up to the elements over the long haul.

But that's only the first part of Strongpanel's four-step protection against rust. Our zinc phosphate coating prepares the galvanized surface for adhesion of the primer and provides additional protection against rust.

Next, we apply a unique two-part coating, a primer paint and then a siliconized polyester finish coating to provide a rich, durable surface color and additional protection. More than just a layer of paint, this coating is actually an oven-cured system of four seperate coatings, each of which contributes to the overall strength and durability of the panel.

Warranty Information

It's warranted twice!

Strong panel steel roofing and siding doesn't just have one warranty, it has two! A limited 25-year warranty on it's color-coated finish. And a limited 10-year warranty against corrosion caused by acid rain.

Now warranties aren't unique. But the way we back ours is. Every sheet of Strongpanel is "signed" with an I.D. number on the back. That's proof that National Steel takes quality seriously and intends to honor its warranty. That's confidence.

How long is a building good for? As long as it keeps standing and does the job you built it to do. So the more a building can stand up to, the better the building, and the more value you get for your money.

A Strongpanel building is as good as it gets in steel panel buildings. It's thicker. It's stronger. It resists rust better. It comes with a 25-year warranty on the paint, and a 10-year warranty against acid rain. And it provides you with more value for your dollar.
