La description
Galvalume steel coil is based on cold-rolled steel strip as
substrate, it is solidified of *5% aluminum, *3.4 zinc and 1.6%
silicon solidi-filed at **0℃ high temperature and composition.
Prepainted galvalume steel coil combines durability, excellent heat
resistance, and formability of aluminum, and those of zinc that
offer high heat resistance and excellent corrosion protection, to
form into this kind of dense crystalline quaternary alloy coated
steel.The surface of the galvalume steel sheet is characterized by
smooth, flat and gorgeous stars, and its base color is silver
white.
Galvalume(Aluzinc) Steel Coil Process
The common manufacturing process is known as the hot-dipping
process. Let's review step by step.
1. Pre-treatment: Through the pre-treatment system, the
contaminants on the surface of the base metal will be removed. It
often includes degreasing, rinsing, pickling, etc.
2. Hot-dip Galvalume Process: After going through the annealing
furnace, steel sheets are dipped into the Al-Zn pool. Then there is
an air knife to remove the extra coating to keep the thickness of
the coating.
3. Inspection & Coiling
The coated steel sheet will go through the quality control system
and then be rolled up for sale.
So the structure of Galvalume steel includes: Base metal
(cold-rolled steel sheets)
The al-Zn coating layer (top and back sides)
