The galvalume & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil
Advantage:
Strong corrosion resistance, 3 times that of galvanized steel sheet.
The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

Galvalume steel coil test:
Strictly follow coating thickness measurement, hardness testing (pencil hardness, scratch hardness), flexibility testing (impact, the shaft bends, T bend, cup drawing, stretch), adhesion test (scratch test), degree of curing test (glass transition test, solvent resistance test, the dry heat test), other performance testing (Pressure spot test, baking test, stain resistance test, chemical resistance test, the abrasion test, Drop test, the coefficient of friction test);
Packaging Details:
Each bare coil to be securely tied with two bands through the eye of coil (or not) and one circumferential.
the contact points of these bands on the coil edge to be protect with edge protectors.
Coil then to be properly wrapped with water proof /resistant paper, it then to be properly and completely metal wrapped.
Wooden and iron pallet can be used or as your requirements.
And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance.
