AASHTO M 232M/M 232-06 Download


Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware
standard by American Association of State and Highway Transportation Officials,



AASHTO M 232M/M 232-06 is identical to ASTM A153/A153M-05 except provisions specified in this document.

This specification covers zinc coatings applied by the hot-dip process on iron and steel hardware. The hot-dip galvanizing process consists of parts being immersed in molten zinc for a sufficient time to allow a metallurgical reaction between iron from the steel surface and the molten zinc, resulting in the formation of Zn/Fe alloy layers bonding the coating to the steel surface.
