Galvalume is a highly durable, corrosion-resistant coating for steel roofing, developed by Bethlehem Steel in the 1970s. It's made by hot-dipping steel coils in a molten alloy of aluminum, zinc, and silicon. This coating, which can be left as a plain finish or painted, offers at least twice the corrosion protection of traditional galvanized steel. Galvalume roofing is a popular, low-maintenance choice known for its longevity, often lasting over 40 years and providing long-term cost savings.

1.What is Galvalume steel coil?
Galvalume steel is carbon steel coated with an alloy that combines the impervious properties of aluminum with the malleability and galvanic protection of zinc. The alloy coating gives galvalume steel coil and sheets a smooth, plain finish.
2.Will Galvalume rust if you cut it?
That's why Galvalume's corrosion resistance is about two to four times better than galvanized steel. Galvalume's self-healing characteristics help control the red rusting at any cut/exposed edges.
3.What are the disadvantages of Galvalume?
Not Suitable for Coastal Areas: Galvalume's coating is not designed to withstand the challenges posed by coastal environments, including properties exposed to crashing waves, expansive bays, marshes, and other coastal settings.
4.When should Galvalume not be used?
Galvalume should not be used in alkaline environments. This is due to the aluminum in Galvalume; it does not hold up well in that type of environment. Galvalume does not do well when damaged.
