ABOUT
ZHONGYANG:
Our factory
manufactured with high-quality material, applying the method of
hardening and tempering and nitriding, thus it enjoys the
characteristics of long working life, wear resistance, and anti
corrosion. Besides, the technique of hard alloy spraying or chrome
plating can be used on the working surface of screw, which will
make it have better using effectiveness. We can supply screw and
barrel for Krauss Maffei ,ShangHai JwellL,CINCINNATI, HaiTian,weber
and so on, we also can make screw and barrel according to your
drawings, we even can design screw and barrel for you as long as
you have connection size.
