  The first results on next-to-leading order QCD corrections to production of
two $Z$ bosons in hadronic collisions in the extra dimension model of Randall
and Sundrum are presented. Various kinematical distributions are obtained to
order $\alpha_s$ in QCD by taking into account all the parton level
subprocesses. We estimate the impact of the QCD corrections on various
observables and find that they are significant. We also show the reduction in
factorization scale uncertainty when ${\cal O}(\alpha_s)$ effects are included.
