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

5. 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.
6. 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.
