The choice of steel plays a big role: steels are used of class 1 supporting the aspect and the mechanical resistance of the coating. However some defects inherent in hot galvanization must be accepted, such as cords of the weldings that one should not deteriorate with sandpapering, of the visual aspects chechmates with possibility of marbled or rough zones and of light run zinc visible along the sections without consequences on the behaviour with corrosion
