AZ30 Aluzinc Raw Material of prepainted steel coil for general building panels

Yearly capacity: 700,000 tons
Thickness: 0.16-2.5mm
Aluzinc coating: AZ30 – AZ185


Galvalume is steel coil with a lamination of Al-zinc alloy. Currently, 15-25% Al-zinc is most widely used in ppgi manufacture. In Jianglin, we are one of the leading manufacture of Al Zn billet.
With the different factory requirement, Al-zinc alloy formula can be different, which can increase the galvaluming process meanwhile, reduce the chance for stopping the production line.

Comparison between Galvanized coil and Galvalume coil

1. Coating type

Aluzinc coating is 55% Al-zinc content, Galvanized coil is pure zinc.
Aluzinc coil can have better anti corrosive ability, based on research.


2. Better production efficiency

For producing Galvanized coil, the furnace need be higher temperature than Galvalume coils. When producing Galvanized coil, the furnace need twice cleaning process at least each month. However, when producing galvalume coil, there is less chance for cleaning the furnace, which can save factory much cost.

Application Guidance:

DC51D+AZ and DC52D+AZ are mainly used for normal cold processing , most widely commercial products including home appliance, furniture. S250GD, S300GD, S350GD, S550GD are mainly used for structure, or construction.

1.Cold Rolling Production

Jianglin is equiped with 3 production lines of 6 rolls rolling machinery guarantee the precise thickness of the coils. Yearly processing capacity is more than 700,000 tons.

2.Galvanizing Production Line

Jianglin is equipped with 3 production lines of galvanizing including one Zinc coating line and two Aluzinc production line. Yearly production is around 600,000 tons. Some of the cold rolled coils are sold to different factories.
For thickness, we focus on 0.3-0.8mm. Most of Shandong market galvanized coil are from Jianglin.

3.PPGL and PPGI Production Line

Jangling PPGI &PPGL is mostly for oversea clients, which has high quality requirement on zinc coating thickness.


Jianglin Steel corporation is strictly applying 6S management system. For past 5 years, though the global steel market is under very tough environment, we have reached up to 5%-9% revenue increase.


There are basically two kinds of packing methods.

Standarded sea freight package Simple package for short delivery


For each and every batch of GI, PPGI, PPGL, we will check all the thickness, surface, and other parameters, just to guarantee the quality. Meanwhile, we have compelte order tracking system to make every coil trackable. Any mistake happening, we will be responsible.


Jianglin with production capacity of 700,000 tons per year, we have been collaborating the listed shipping companies in the world including COSCO, WORLD WIDE LOGISTICS, CMA, and other shipping companies. During the peak season when containers are hard to book, we always enjoy the previlige to book the shipment with a suitable price and schedule
