- Unilume steel consists of aluminum (55% in weight ratio but 80% in surface volume ratio), zinc (43.4% in weight ratio), and silicone (1.6% in ratio) so it has both aluminum-unique corrosion-resistance and heat resistance and zinc-unique "galvanic behavior"
As outdoor exposure test(for 13years), Unilume is at least 3~4 times superior to galvanized steel.
