SURFACE APPEARANCE

Surface appearance	Description
A	Some defects are allowed such as pores, slight indentations, small marks, minor scratches and slight discolouration that do not affect the formability or adhesion of subsequent surface coatings.
B	The best side should have no imperfections that could potentially jeopardise the even appearance of a high-quality paint finish. If only one side is coated, this requirement will be applicable to the uncoated side, unless otherwise agreed. The other side must at least meet the requirements of the side with appearance A.

SURFACE TREATMENTS EN 10152

SURFACE TREATMENTS Symbol	Type of treatment According to EN 10152
P	Phosphated
PC	Phosphated and chemically sealed
C	Chemically passivated
PCO	Phosphated, chemically sealed and oiled
CO	Chemically phosphated and oiled
PO	Phosphated and oiled
O	Oiled
U	Uncoated, untreated

ELECTROLYTIC ZINC COATING

1) A coating density of 50 g/m² corresponds to a coating thickness of approximately 7.1 µm.
