Our analysis shows that SM-like electroweak phase transition (EWPT) in the$SU(2)_1 \otimes SU(2)_2 \otimes U(1)_Y$ (2-2-1) model is a first-order phasetransition at the $200$ GeV scale (the SM scale). Its strength ($S$) is about$1 - 2.7$ and the masses of new gauge bosons are larger than $1.7$ TeV when thesecond VEV is larger than $535$ GeV in a three-stage EWPT scenario and thecoupling constant of $SU(2)_2$ group must be larger than 2. Therefore, thisfirst order EWPT can be used to fix VEVs and the coupling constant of the gaugegroup in electro-weak models.
