Galvanized zinc steel coil

HOT-DIP GALVANIZED I-BEAM is also called hot-dip galvanized I beam or hot dip zinc beams are immersed after rust steelh-500 degrees Celsius melts in zinc, beams attached to the zinc layer on the surface, to serve as an antiseptic purposes, suitable for all kinds of acid and alkali mist and other corrosion environments
HOT-DIPPED GALVANIZED COIL is characterized by protection base metal(Fe) as corrosion resistance of zinc itself and acts effective sacrificed-anodic of zinc. It is characterized by extremely excellent workability due to produce by continuous annealing, temper rolling and after treatment process.

Size Range: 0.125~2.5mmX 50~1500mmXC; both narrow strips and wide coils are available
Zinc coating: Z40, Z60, Z80, Z100, Z120, Z140, Z180, Z220, Z275 or as per customized.
Coil ID: 508mm/610mm Coil weight: 5~20MT
Surface: regular/minimized spangles, chromate, skin pass or not, chromate 6 or free,
55% AL-ZN COATED STEEL COIL is a steel substrate coated on both sides with an aluminum-zinc alloy with the composition of the coating, 55% aluminum, 43.4% zinc and 1.6% silicon. The excellent corrosion resistance of Aluzinc is a result of the properties of the two metallic substances: the barrier effect of the aluminum existing on the surface of the coating and the sacrificial protection of zinc.
