GL Galvalume Steel Coil And Sheets For Various Colors Of PPGL In Coil And Sheet
1. Mechanical properties of hot dip Al-Zn base
Mechanical properties of steel sheet and steel strip should be in conformity with the stipulations of following table.
Due to 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.
2. Specification
GL is more popular in recent years, especially popular in Philipine due to the merits of PPGL, which suitable for the enviroment there well.
Firstly, the corrosive resistance of the hot-dip alu-zinc coated steel sheet is twice to fifth times as mush as that of the hot-dip zinc- coated base metal.
Secondly, it can satisfy the processing requirements of rolling, coiling and others processes alike.
Thirdly, the color won't change while continuously or intermittently working with an ambient temperature up to 316℃.Neither serious oxygenation nor oxide scale might appear while continuously or intermittently working with an ambient temperature up to 490℃.
Thirdly, the heat and the light reflected are respectively twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.75, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction material of saving energy.
