Under steel standard EN 10292,HX260YD,H260YD,HX260YD+ZF,HX260YD+Z,H260YD+ZF,H260YD+Z galvanized steel coil and sheet are mainly used for roofs and outer walls.For galvanized steel plate HX260YD,Y is short for interstitial free steels whose composition is controlled to achieve improved values.Especially for controlled Mn chemical.Chemical passivation and oiling treatment for galvanized steel plate,HX260YD,H260YD,HX260YD+ZF,HX260YD+Z,H260YD+ZF,H260YD+Z ,this agreement may be reached on this combination of surface treatment if increased protection against the formation of white rust is required.Besides,sealed and phosphated treatment also can be chosed by customers.

Xinsteel suggest customers accept the surface quality treatment,normally choose Class B,improved surface,with this surface quality,small imperfections such as stretch leveling breaks,skin pass marks,scratches,indentations,spangle structure and zinc run-off marks and light passivation marks are permissible.
