Q. If something has been hot dipped galvanized does that mean that it has been done in accordance with the ASTM A153 or ASTM A123 ? Or are there other standards that can be looked at in relation to being hot dipped galvanized.
In other words does ASTM 153 or 123 dominate the industry standard for hot dipped galvanized products?

I am working on an Army Corps of Engineers submittal and I can't quite find specifications or catalog cuts that relate to my ferrous metal hardware being hot dipped galvanized in accordance.

I won't take offense to a rude answer as long as it is a answer.

A. ASTM A123is a general hot dip galvanizing specification for items not otherwise specified (hardware, sheet & wire have more specific HDG specs). Ten grades can be specified, with thicknesses of 35 to 100 microns. Small coating irregularities due to geometry and some 'renovation' (coating touch-up per ASTM A780 ) are permitted.

ASTM A153 is for fasteners and other hardware small enough to centrifuge to remove excess zinc after dipping. No drips are allowed, and thicknesses are specified for threaded parts. The specifications overlap; threads on parts hot dipped per A123 must conform to A153.
