Galvanized Sheet Metal Strips Thickness Customized Corrosion Resistance

Alu-zinc Galvalume Steel Coils And Sheets 55% GL Various Thickness

1. Description

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. Mechanical properties of hot dip Al-Zn base

Mechanical properties of steel sheet and strip should be in conformity with the stipulations of following chart.
Because the effects of aging, mechanical properties of the steel strip shall deteriorate with storage time passing, E.g. yield strength and tensile strength will rise, elongation after fracture decreases, formability deteriorates etc. it is suggested to use the material as soon as possible.

For products with nominal thickness greater than 0.50mm, but less than or equal to 0.70mm, the elongation after fracture is allowed to decrease by 2 units. For products with nominal thickness not greater than 0.50mm, the elongation after fracture is allowed to decrease by 4 units.

3. 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.

4. 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.

5. Packing

Standard Seaworthy Export packing:peripheral anti-rust board, inside anti-rust paper, plastic cannula, latitude strapping, radial srapping, etc.
