The American Galvanizers Association (AGA) has assembled three industry experts to provide an informative webinar on recent developments in the use and performance of Hot-Dip Galvanized (HDG) rebar. HDG rebar has emerged as a solution to the transportation industry’s objective to provide concrete bridge decks and substructure units a 75-100 year design life with minimal maintenance.

Participants will learn about HDG rebar production and the corrosion protection zinc provides to reinforcing steel. Speakers will discuss relevant industry standards for specifying HDG rebar. The proven performance of HDG rebar through case studies of structures in service for over half a century will be presented, along with the criteria and rationale used by selected state DOT’s and Authorities regarding the use of HDG rebar.

How HDG rebar provides the lowest cost of ownership shown through life cycle cost comparisons of HDG with other competitive products.

Learning Objectives:

At the completion of the webinar, participants will be better informed on specifying corrosion resistant reinforcing steel for their next transportation project. Viewers will also be able to:

  • Understand how hot-dip galvanized (HDG) rebar provides corrosion protection for reinforcing steel in concrete
  • Demonstrate HDG rebar performance with real world examples
  • Understand the current criteria of various state DOTs and Authority’s, and their corrosion protection criteria for various bridge types
  • Recognize the ability of ASTM A767 (Class 1) HDG rebar to provide 100-year life without major maintenance

Viewers who complete the session will receive one Professional Development Hour (PDH) credit.
