Products Standard of hot dipped galvalume aluzinc steel coil
Hot dipped galvalume steel coil is an alloy steel plate composed of 55% Aluminum, 43.5% Zinc,1.5% Silicon. Hot dipped galvalume steel coil demonstrates stable anti-rust and anti-corrosion ability in various acid and alkaline, humid, and rainy environmental tests. So, galvalume steel coil has a wide range of applications in the industry. Mainly production standard as below:
Chinese Standard: GB T 2518
Japanese Standard: JIS G 3321
American Standard: ASTM A792
Europe Standard: EN 10346

Surface Treatment of hot dipped galvalume aluzinc steel coil
There are many surface treatment processes for galvanized coils, and the surface treatment requirements are different according to different uses. The following are common surface treatments,
Hot-dip coated flat products receive one of the following surface treatments at the producer’s plant :
chemical passivation: C
oiling: O
chemical passivation and oiling CO
Anti Fingerprint AFP
The period of protection afforded is limited and depends on the atmospheric and storage conditions.
Hot-dip coated flat products are only supplied without surface treatment (untreated (U)) if expressively desired bythe purchaser on his own responsibility. in this case, there is increased risk of formation of corrosion products onthe surface during storage and transportation.
Chemical passivation protects the surface against humidity and reduces the risk of formation of corrosion productsduring storage and transportation.
Local colour variations as a result of this treatment is permissible and does not impair the quality.
Oiling treatment also reduces the risk of formation of corrosion products.
It shall be possible to remove the oil layer with a suitable degreasing solvent which does not adversely affect the coating.
Chemical passivation and oiling
Agreement may be reached on this combination of surface treatment in accordance with Oiling treament and Chemical Passivation if increased protection against the formation of corrosion products is required.
Anti Fingerprint
Our anti-fingerprint coating is an organic coating approximately 1 micron thick that creates an additional barrier
Not only does it prevent corrosion, it also provides a temporary protective coating during transportation and storage, it is antistatic and can produce
Ideal for gluing and painting as this treatment provides a smooth, pre-primed and ready-to-paint surface
Most paints. During the mechanical forming process, the coating acts as a dry lubricant, helping to reduce sticking on the tool.
In addition to the surface treatment mentioned above, it also includes Skin-pass, Chromate, Unoiled, Dry etc.
