This allows the same reinforced con-crete design specifications (bar size, lap lengths, etc.) to be used for galvanized rebar as unprotected rebar. 3 Straight lengths of galvanized rebar Galvanized rebar stored at job site Microstructure of a hot dip galvanized coating Rebar emerging from the molten zinc bath Eta (100% Zn) 70 DPN

The galvanised coating

The formation of the zinc-iron alloy coating depends principally on the chemical composition of the steel that is galvanized. All common steels and irons can be hot dip galvanized, but steels with particular silicon contents may produce a very fast reaction between the iron and the zinc (read below about Galvanizing reactive steel).

. Q: "What is hot dip galvanizing CLASS B-2?" Answer: Class B-2 is a materials classification from ASTM A153 for hardware products such as castings, fasteners and miscellaneous threaded objects that are centrifuged, spun, or otherwise handled to remove excess zinc. Class B is refers specifically to rolled, pressed, and forged articles.

Galvanizing

Hot-dip galvanizing has been utilized for over 250 years to protect steel and iron from the destruction of corrosion. The process, which has evolved over the years, entails dipping fabricated steel into a kettle of molten zinc. The iron in the steel reacts with the zinc to form a tightly bonded alloy coating which protects the steel from corrosion.

Distortion & Warping

With proper consideration and understanding of how the hot-dip galvanizing process affects steel, asymmetrical designs or structures containing sections of unequal thickness can be successfully galvanized, as can fabrications where cold-working techniques (bending, hole
