ARA Corp's Aluminum-zinc alloy-coated Steel Sheet (GL)
What is Galvalume : 55% ALUMINUM –ZINC ALLOY COATED STEEL.
Galvalume (GL) ideally combines characteristics of aluminum coated steel and galvanized steel.
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 silicon (1.6% in weight ratio) so it has both aluminum-unique corrosion-resistance and heat resistance
and zinc-unique “galvanic behavior”.
“ARA CORP GALVALUME”, it is new concept steel, which is produced by Korea Galvalume Aluminum-zinc alloy-coated Steel Sheet Mill’s advanced
Technology, is widely used in various kinds of industry such as building interior or exterior, electricity,
Electronic appliances, automobile parts, and drain pipe, due to its high quality and economical efficiency.
Durability - Humidity Test, Salt Spray Test, Outdoor Exposure Test ( for 13 years).
Heat-Resistance – Heat-Resistance of Galvalume is far superior to that of galvanized, and
almost equal to characteristics of Al-coated steel.
Galvanized : Recommendable temperature ; 230°C & under, Discoloration at 250°C
Galvalume : No discoloration even for durable use at 315°C
Weldability - spot and seam welding test pass.
Workability - GL has the same characteristics with galvanized steel sheet in workability & formability, and
especially, micro crack at forming section is much less than galvanized steel sheet.
Therefore, GL has excellent durability at forming section.
Heat-Reflexibility - GL's heat reflexibility almost doubles that of galvanized steel so it has an energy
saving effect. If it is used in roofing and paneling without painting
Paintability – Galvalume can be painted without pre-treatment or weathering when used for signboard or
general purpose, due to its superior adhesive strength between zinc layer and paint,
unlike galvanized steel which requires weathering or pre-treatment.
Surface Treatment. : Chromated, Anti finger Printed, Oiled, CR-Free.

Packing
Steel Plate has lots of good quality: surface is smooth, high plasticity, toughness and mechanical strength, resisting acid and alkali corrosion of gas, solution, and other media.Galvalume Aluminum-zinc alloy-coated Steel Sheet is a kind of alloy steel and not easy to rust, but not absolutely not to rust. Stainless steel plate can resist weak media such as air, Steel Plate steam and water corrosion resistance of steel, acid steel plate refers to the nedia, resisting chemical etching media such as acid, alkali, Galvalume Aluminum-zinc alloy-coated Steel Sheet salt corrosion of the steel plate. Since the beginning of the 20th century, and stainless steel plate has a history of more than a century.
