Epoxy coated rebar presents a particularly troublesome problem. Steel
heads act like an electric hammer, striking any rebar or forms they
contact, over 10,000 times per minute, with a force from hundreds to
over 2,000 pounds per blow. Contact with a steel vibrator head of as
little as one second can chip enough coating to subject the steel to
deep rust. Oztec's patented High Efficiency "RubberHeadTM" vibrator
head not only meets DOT non-metal head specifications for protecting
coated rebar and expensive forms, but exhibit some very special and
unique properties. The High Efficiency "RubberHeadTM" urethane dimpled
construction sends strong shock waves off the entire length of the
head, with a larger radius of action, producing denser concrete with
less voids to patch.
