Prepainted GALVALUME sheet combines well with most other building materials and treatments. Its versatility allows it to be used almost anywhere on building exteriors, assuring compatibility and simplicity in the overall design approach. GALVALUME is sheet steel with a hot dip-applied alloy coating of about 55% aluminum and 45% zinc. Its excellent corrosion resistance has been proven by field performance on buildings for more than two decades. An estimated 40 billion square feet of prepainted GALVALUME sheet covers buildings in all kinds of climates and environments in North America, Europe, Asia and Australia. The combination of long-lived GALVALUME sheet with a wide range of modern high-performance paint systems results in a functional, durable, eye-appealing building product.

Ensuring that prepainted GALVALUME sheet will give the best possible performance is the joint responsibility of building panel manufacturers, architects and contractors. But even the best products can perform better if they are used with that extra attention to detail characteristic of quality and craftsmanship.
