Frequently Asked Questions

I'm interested in specifying hot-dip galvanizing for reinforcing steel. Are there any concerns with fabricating rebar after galvanizing?

   

Rebar is commonly fabricated after galvanizing. In order to minimize the possibility for coating damage, avoid bending the rebar at a radius of more than 8 times its radius. ASTM A 767, Specification for Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement, has a table that provides maximum bend diameters for various-sized rebar.
