Fall 2019 | Vol. 1 | No. 3 Your Global Resource for Infrastructure Protection H Galvanized Reinforcing Steel Delivers Years of Corrosion Protection By Philip G. Rahrig, Executive Director for American Galvanizers Association ot-dip galvanized reinforcing steel placed in concrete bridge decks and pre-cast panels has provid-ed corrosion protection in many cases for more than 50 years. Cored samples in these structures indicate the steel substrate will not experience corrosion for many decades beyond. Until the past five years, there has been only one commonly used method of galvanizing reinforc-ing steel, which is immersing individual cut-lengths into a kettle of molten zinc until the impervious zinc alloy coating is formed. More recently, though, proprietary versions of that method and a continuous strand method have been developed to of-fer complementary products for inclusion in any project requiring straight lengths, fabricated chairs, and column cages.
