Galvalume Steel Gi Sheet Coil Aluzinc ASTM JIS EN Strip Zinc Coated
Galvalume steel GI Sheet Coil Aluzinc 1500mm ASTM JIS EN GB Strip Zinc coated gi sheet coil
What is Galvalume steel?
Galvalume is comprised of a steel sheet dipped in a coating of 55% aluminum, 43.4% zinc, and 1.6% silicone.
The unique coating gives the steel greater protection from the elements, which allows it to outlast traditional
galvanized steel.
What is Aluzinc steel?
Aluzinc steel is a super material compared with regular Galvanized Steel. Aluzinc is a coating material formed
from a mixture of Aluminum (55%), Zinc (43.4%) and Silicon (1.6%). Durable and long-lasting, it provides superior
performance and corrosion resistance under all environmental conditions.
What is GI coil?
Galvanized Steel Coils / Sheets (GI) JS METALS is a leading supplier of galvanized steel sheet & coil. Galvanized
steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to
produce galvanized steel: continuous hot dipping and electro-galvanizing.
