Printing Pre Painted Aluminum Coil Polyester Paint JIS G3322 CGLCC Corrosion Resistant

Printing Pre Painted Aluminum Coil Polyester Paint JIS G3322 CGLCC

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

9) requirements on packing and dispatch

3. Applications

1) Construction:

Outside: workshop, agricultural warehouse, corrugated roof, wall, retailer booth, roller shutter door, etc.

Inside: door, doorcase, ceiling, elevator, stairway, vent gutter, etc.

2) Electrial Appliance: refrigerator, washer, switch cabinet, desk, bed, micro-wave oven, bread maker

3) Furniture: central heating slice, lampshade, chifforobe, desk, bed, locker, boofshelf

4) Others: writing panel, garbage can, billboard, 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. Our Advantage: Strictly Quality Control of Production

Inspection for quality of surface coating on the line supervises and controls the apperance effectively to ensure the quality of coating.

The testing for physical performance follow the principle of one coil, one sample. In order to have traceability of every coil's quality, we test T bend, impact, cupping, MEK, gloss, chromatism to ensure quality. Ultraviolet aging test and Salt spraying test apply to special requirement products.
