Mr. Richard L. Trate, Managing Director – Stainless Rebar of Carpenter Technology Corp., USA reports that over 200 tons of stainless steel reinforcing bar was recently supplied to The Fort Miller Co. of Schyulerville, NY. The Carpenter 2205 duplex alloy rebar was used to produce pre-cast concrete modules for a new NYSDOT-designed highway bridge. The bridge will be on the Belt Parkway, over the Ocean Parkway, in Brooklyn, NY. Fort Miller pre-cast the modules in a climate-controlled facility and then completely assembled the structure on their property. After inspection, the bridge will be disassembled, moved to the site and re-assembled quickly and efficiently. The modular approach and the use of stainless steel rebar helped meet the two main objectives specified by NYSDOT: to erect the bridge in a busy urban area with minimum disruption to traffic and the surrounding neighborhoods; and to erect a bridge that will last a lifetime with minimal maintenance. Carpenter Technology believes this to be the first major use of stainless rebar in a pre-cast application in the USA. The use of stainless rebar added only about 1% to the total project cost and it will greatly extend the bridge lifetime.
