GNEE Company customer case:
Under european steel standard EN 10292, hot-dip galvanized steel sheet and coil
HX300LAD,HX300LAD+Z,HX300LAD+ZF,H300LAD,H300LAD+ZF,H300LAD+Z,for the name of HX300LAD+Z zinc coated steel coil,LA is short for low alloy or micro-alloyed steels containing one or more of alloy Nb ,Ti and V to achieve required proof strength levels.
Hot-dip zinc coated steel plate HX300LAD, HX300LAD+Z, HX300LAD+ZF, H300LAD, H300LAD+ZF generally receive surface protection at rolling plants. The period of protection afforded depands on the outside atmospheric conditions.
These surface protection for galvanized steel plate and coil HX300LAD,HX300LAD+Z,HX300LAD+ZF,H300LAD,H300LAD+ZF including Chemical passivation,Oiling,Chemical passivation and oiling,sealed,phosphated and untreated.
Generally the galvanized steel sheet HX300LAD, HX300LAD+Z, HX300LAD+ZF, H300LAD,H300LAD+ZF shall be done surface treatment after rolling, if when customers indicate in their purchase order without surface treatment terms, we can deliver these galvanized steel materials under untreated condition.In this case, there is increased risk of atmospheric corrision.
Galvanized Steel Plate:

The steel HX300LAD (X=roll condition, LA=low alloyed, D=hot-dip coatable) is producible with the following coatings: - HX300LAD+Z (plating Zn) with coating weights (double-sided) of 100, 140, 200, 225 and 275 g/m² (100 g approximate 7,1 µm per side) - HX300LAD+ZF (plating Zn-Fe) with coating weights (double-sided) of 100 and 120 g/m² (100 g approximate 7,1 µm per side) - HX300LAD+ZA (plating Zn-Al) with coating weights (double-sided) of 095, 130, 185, 200 and 255 g/m² (95 g approximate 7,2 µm per side) - HX300LAD+AZ (plating Al-Zn) with coating weights (double-sided) of 100, 150 and 185 g/m² (100 g approximate 13,3 µm per side) - HX300LAD+AS (plating Al-Si) with coating weights (double-sided) of 060 and 080 g/m² (100 g approximate 17 µm per side) The hot dip galvanizing refined flat products are available by arrangement on ordering with different coating weights (also per side).
