DX51D SGCC PPGI Steel Coil , Pre Painted Aluminium Sheet For Building Material

Building Material Pre Painted Aluminum Coil ASTM, GB, JIS DX51D+Z

1. Descprition about base metal

Galvalume is the result of an ideal alloy of aluminum and zinc. It consists of aluminum(55%), zinc(43.4%), and silicone(1.6%).

Characteristics of Galvalume:

1) Corrosion resistence:

At verious enviromental conditions, GL shows better corrosion resistence than GI if the thickness is same, its service life is 2 to 6 times than ordinary galvanized steel. The corrosion resistence in the machining parts is much better than that of hot-dip galvanized due to micro cracks demormation parts of aluminum zinc plate is smaller than hot-dip galvanized.

2) Heat resistence:

GL plate can be used for a long time even if under 315℃.

3) Heat reflective

The reflection coefficient is double than that of hot-dip galvanized steel, which can reduce the inner tempeture in summer

2. Information to be supplied by the purchaser

The following information is required from the purchaser so that we may supply the products to confrom with the requirements:

1) complete designation

2) where appropriate, details on the required decorative properties(color, gloss, embossing, printing) and required subsequent surface treatment

3) other requirements on the characteristics of the products

4) nominal dimensions of the product related to the substrate

5) quantity

6) internal and maxinum external diameter and mass limit for coils, or limit dimensions and mass limit for the bundles of sheets

7) type of test and type of inspection document

8) slection of the test methods and specification of the mininum or maximum calus for the relevant properties

9) requirements on packing and dispatch

3. Quality Assurance

HANKE has already passed the authentification by the ISO9001, ISO14001 and KS D 3520 in succession and established a completed set of quality assurance system, and under this system, there has a complete set of regulations for ordering, order handling, quality design, purchasing raw materials, working production schedule, production, test, inspection, packaging, storage, delivering, etc.

4. Details for Main applications

1) Construction

The prepainted steel sheet for construction is an attractive substitute for wood and other materials owing to its advantages, including excellent and fast color, good durability performance, chalking resistence, good corrosion resistence, etc, it is an efficient construction material, with energy saving, preventing pollution and good economic effect. At the same time, various colors , surface structures and coatings provide products with great flexibility and option.

2) Electrial Appliance

The prepainted steel sheet for household appliances often takes electro-galvanized, hot-dip zinc-coated and color rolled steel sheet as its base metal, which is widely applied in manufacturing refrigerators, large-scale air-conditioning systems, refrigerating cabinet, bread maker, furniture,etc.

5. Advantages of HANKE PPGI:

1) Such as: fast color, good durability performance,chalking resistance, etc.

2) Minimized the maintenance cost.

3) Various colors, surface structures and coatings provide such products with great flexibility and option.

In China, more than 90% color coated sheets are applied in construction.
