Galvalume
(Aluminum-zinc alloy coated steel)
Product introduction
 |
Galvalume steel is the result of an ideal alloy of aluminum and zinc.
It consists of aluminum (55% in weight ratio but 80% in surface volume ratio), zinc(43.4% in weight), and silicone (1.6% in weight ratio) so it has both aluminum-unique corrosion-resistance and heat resistance and zinc-unique "galvanic behavior". |
