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.
