Electro Galvanized Flat Steels
Electro Galvanized Flat Steels Suitable
for Cold Forming
EN 10152 : 2009
This type of flat steels provide advantage for forming with their minimum level of yield strength and tensile strength. Qualities coming after DC01+ZE; have more operation capability of drawing, forming in presses and cold forming. Besides these, operation, weldability and paintability of these are the best among all coated flat steels.

1) For thicknesses of ≤ 0.70 mm, but > 0.50 mm, a 20 MPa higher maximum yield point value is permissible. For thicknesses ≤ 0.50 mm, a higher maximum yield point value of 40 MPa is permissible.
2) For thicknesses of ≤ 0.70 mm, but > 0.50 mm, the minimum values for fracture elongation are reduced by 2 units, for thicknesses of ≤ 0.50 mm by 4 units.
3) r90 and n90 values are valid for > 0.50 mm thicknesses.
