What is Galvalume TM

Developed by BIEC International Inc., Galvalume is a 55% Aluminum - 45% Zinc alloy coating for steel. Metal roofing is one of the largest applications for Galvalume.  It is also used for automotive, appliances, and in other industries where its corrosion resistance and high heat reflectivity is required.

The Galvalume coating  is applied using a continuous hot-dip process.

Galvalume metal roofing brings together the qualities of aluminum and zinc.  The combination doubles the corrosion resistance of galvanized metal roofing alone. The aluminum-zinc coating also provides corrosion resistance and heat reflectivity. It enhances bare edge protection and helps make possible the multiple forms and shapes required of metal roofing.

Unpainted, it is silver-like.  Most often it is available painted.
