Gerdau Ameristeel Launches ZBAR(TM), Next Generation in Reinforcing Steel Corrosion Protection

    KNOXVILLE, TN, June 2 /PRNewswire-FirstCall/ - Gerdau Ameristeel
 Corporation (TSX: GNA.TO, NYSE:   GNA) - Gerdau Ameristeel announced today
 the introduction of a new patent pending dual coating process for concrete
 reinforcing steel. This process involves applying a thermal-bonded zinc
 inner layer combined with a thermal-bonded polymer outer layer to a
 conventional reinforcing steel bar. The innovative process and product,
 called ZBAR(TM), provides extra protection against corrosion.
     "We are excited to introduce a new product for the construction
 industry that will help protect and extend the life of concrete
 structures," said Neal McCullohs, Vice President of Downstream Operations
 for Gerdau Ameristeel.
     ZBAR(TM) has been evaluated per ASTM A944, is readily available and can
 be substituted for any reinforcing steel product. ZBAR(TM) consists of
 using A615 or A706 reinforcing steel bars combined with two powerful
 corrosion barriers, each with uniform thickness.
     "Lab results show that a concrete structure using ZBAR(TM) has more
 than sufficient resistance to chloride-induced corrosion for an expected
 lifetime of 100 years," states Dr. Gerardo Clemena, Ph.D., principal
 research scientist for the Virginia Transportation Research Council.
