TECHNICAL CHARACTERISTICS
| Coating | Z50 up to Z725 g/m2 Coating is expressed in weight of zinc (g) over one square meter of product (total of two sides). |
| Surface finishes | A (normal appearance) Standard finish for industrial use B (improved surface) Skinpassed surface B1 (smooth) Smooth cylinder skinpass B2 (bright) Double smooth cylinder skinpass C (superior) Highest standard of finish |
| Surface appearances | N – Normal spangle
M – Reduced spangle |
| Surface treatments | Oiling Surface protection from oxidation, with improved suitability for plastic deformation. Chromating Chromate conversion coating resulting in the formation of a passivating film. Only trivalent chromium is employed. Ecorsteel® Transparent or semi-transparent organic coating with special protective, lubricant and antifingerprint properties. No-rinse Pre-treatment to allow subsequent painting cycle by purchaser. |
