The Standard Model is in agreement with all experimental results. But many issues like masses and mixing angles can not be explained. This suggests new physics beyond SM. In particular the SU(3)_CxSU(3)_LxU(1) is a model beyond the SM. The most important point of this model is that it can explain 3 families of fermions at low energy by triangle anomaly cancelation. Two families of the quarks are in 3-plet. The other family of the quark is in anti 3-plet. And the 3 families of the leptons are in anti 3-plet. I will discuss the different type of 331 models, and the particle contents, fermions, Higgs and gauge bosons. In particular, I will discuss the Z' production in Tevatron and LHC. Using collision data collected by the CDF II detector at Fermilab Tevatron, the 331 Z' boson is excluded with masses below 920 GeV.
