0.7mm Regular Spangle Galvanized Steel Coil Chromated 6+ GB/T 2518-2008

0.12—1.5mm Sheet or coil coated with Aluminium and zinc alloy (Aluzinc) ALZN Regular Spangle Chromated 6+ S350GD

It is a good substrate for organic coating it is generally used in the manufacture of wide sections for wall cladding and insulation cladding. Supplied with a very thin organic finger print free coating for even better performance. In addition to preventing fingerprinting it also reinforces the temporary protection of the material during transport and storage. It acts as a dry lubricant and improves its forming and deep drawing performance.

In addition, it also permits the direct application of paint, without preliminary surface treatment. The many advantages of this product are highly valued in applications such as roofing sections and cladding. Material has a continuous hot dip double-sided coating. Can also be supplied with a moisture barrier for use as metal jacketing for power stations or alternatively with an acoustic barrier with significant labour saving and enhanced engineering properties (Soundmet).

Composition aluminium (55%) Zinc (43.4%) Silicon (1.6%)

Sizes – Thickness 0.25mm – 2.00mm width 1000mm , 1219mm , 1250mm

Material with 185 g/m2 coating AZ185 Skin Passed Anti fingerprint lacquered coating DX51 Substrate

Can be supplied as coil or flat sheet.

Another alternative for increased rigidity is to use a Petrochem profile. The profile allows for thinner material to be used in some instances without losing rigidity. Standard thicknesses are 0.4mm to 0.8mm. Our Aluzinc product ALZN can also be combined with DryMet this adds a PSMB Surlyn barrier to the underside to prevent corrosion attacks from the internal surface that comes into contact with insulation often with changing temperatures and moisture. As well as the standard ALZN-D (Aluzinc with DryMet) it is also available with a ZX profile also called petrochem finish. Our version is ALZN-ZXD combines the performance of Aluzinc, the strength and rigidity of the ZX profile and the internal protection of the Surlyn moisture barrier.

This type of product is also referred to as AluzincTM GalvalumeTM or ZalutiteTM

OVERVIEW OF ALUZINC STEEL COIL

Also known as galvalume or zincalume steel, aluzinc steel is a form of cold rolled galvanized steel with metal coating composed of 55% aluminum, 43% zinc, and 1.6% silicon. Its unique composition gives aluzinc steel some distinctive features by the combination of the physical protection and high durability of aluminum and the electrochemical protection of zinc.

FEATURES OF ALUZINC STEEL COIL

• Superior long term corrosion resistance allows aluzinc steel coils to outperform galvanized coating by 2 to 6 times
• The density of 55% aluminum is smaller than that of zinc. With the same weight and thickness of the plating layer, the area of the galvalume steel sheet is 3% or larger than that of a galvanized steel sheet.
