The zinc coating shall withstand bending, without flaking (peeling), when tested in accordance with provisions in ASTM A653. There are no established standards with respect to flaking of the coating during drawing operations; hence, this is subject to negotiation. If the forming is severe, the use of Weirkote Plus Galfan is recommended to prevent flaking.
