G550 Galvalume Steel Coils And Sheets 55% Aluzinc Corrugated Roofing Sheets
1. Storage of products
Coils or Sheets should be stored in a dry and ventilated room, instead of being stored in the open air or a place with moisture and a great change of temperature.
The products should be stored in a clean enviroment, preventing from various corrosive substances.
The storage place should be smooth and level, have a good bearing capacity.
Horizontal steel coil should be placed on the brackets with rubber cushions or wooden cushions and be locked with the lock catch on the topside. It mustn't be placed on to the fround or vehicles directly.
To avoid being pressed, the steel coil mustn't be stored in stacking. When the steel sheets are stored in stacking, a limit to every stack should be specified and the sheets with large weight and size should be placed in the lower part of the stack.
The storage of the steel sheets and coils should be scientifically arranged in advance, so as to avoid unnecessary shifting.
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.
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.
