1. Galvalume Corrugated Steel Sheet finish introduction
Galvalume finish utilizes a perfect blend of aluminum and zinc (55% aluminum and 45% zinc) to
coat a durable steel substrate. A small amount if silicon is also introduced to the coating to ensure
an even and durable adhesion.


2. Galvalume Corrugated Steel Sheet benefits
1) Combine excellent barrier corrosion protection of aluminum with galvanic protection of  zinc 
2) Easy to install, high strength and lower costs
3) Primarily, its long-term resistance to corrosion makes it an ideal solution for roofing, siding
4) Continuous hot-dip process employed for applying the finish ensures cut edge protection
meaning greater resistance to corrosion along sheared edges
5) On top of all of this advanced protection, Galvalume is still cheaper than stainless steel,
adding to its popularity as the go-to material for rugged outdoor applications


3. Galvalume Corrugated Steel Sheet main structure
It is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot-dip process described
in Production Methods. The nominal coating composition is 55% aluminum and 45% zinc. A small
but important amount of silicon is included in the coating alloy


4. Galvalume Corrugated Steel Sheet application
It is most commonly used for commercial, agricultural, and industrial purposes, however, it is now
also being recognized as an excellent form of residential roofing


5. Galvalume Corrugated Steel Sheet installation tips
1) Prepare roof surface by removing old roofing, rotten wood,adding roofing felt to entire surface
2) Calculate the number of sheets of corrugated metal needed
3) Place your first metal sheet in a corner of the roof, flush against the surface
4) Nail in the first metal sheet to the wood of the roof
5) Place the second metal sheet alongside the first with an overlap of 3 to 4 inches (10 cm)
6) Nail the second metal sheet to the roof
