Because of the sacrificial nature of the zinc, the coating provides corrosion protection for areas of exposed steel surfaces, such as cutting edges and areas where coating has damaged (scratches, impacts, etc.). The answer is simply that it is difficult to directly measure the thickness accurately. 3.2.5.1 Discussion—Solidification of the zinc coating is typically uncontrolled, which produces the variable grain size associated with this finish. The product can be pretreated by zinc-phosphating or alternative pretreatment suitable for zinc-based coated steel in receiving plant to improve the coating adhesion. Ventilation of the workplace must be arranged properly because welding of zinc-based coated steels produces welding fumes containing zinc oxide. For G90, this is 0.32 oz/ft2. Thickness mm.
