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

4. 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.
| Grade | Tensile test | ||
| Yield strength (Mpa) | Tensile strength (Mpa) | Elongation A80% | |
| DC51D+AZ | - | 270~500 | 22 |
| DC52D+AZ | 140~300 | 270~420 | 26 |
| DC53D+AZ | 140~260 | 270~380 | 30 |
| DC54D+AZ | 120~220 | 270~350 | 36 |
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.
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.
