When you buy galvanized metal from a producer or supplier, you are guaranteed only that the zinc coating you paid for is the correct coating weight, not the corrosion protection it provides. You assume, based on ASTM standards, that heavier zinc means better and longer protection. And that used to be true. But not any longer.
InterCoat®ChemGuard means less zinc, but longer protection. And even though no one in the industry will give you assurance of performance, we will. Here is a very simple warranty; it states clearly that very low weight zinc coatings will greatly outperform heavier weight zinc coatings in the standard corrosion tests (ASTM B117 Salt Spray).
Very clear, very simple, very strong. You can rely on this product and here is our statement to prove it.
