值得驕(jiao)傲(ao)的(de)是,津西生產的(de)電氣化鐵(tie)路接觸(chu)網支柱用(yong)熱(re)軋H型鋼（津西高鐵(tie)線桿）在工程建設中被選用(yong),助力蜀道變通途！
成貴高鐵是我國第一條按照中國國家鐵路集團有限公司頒布的《鐵路工程綠色通道建設指南》設計的鐵路，是中國首條綠色山區鐵路，綠色環保的設計理念貫穿始終。而津西生產的高鐵線桿不僅重量輕、強度高、壽命長，而且可回收利用、不污染環境，施工強度小、速度快、工期短，可以節省大量人力物力，同時強韌性能好、可焊接性、機械加工性能好，用于支撐電氣化接觸網，在施工過程中，最大限度的減少施工對環境的影響，有效縮短施工工期。
成貴(gui)高(gao)(gao)(gao)鐵(tie)(tie)(tie)是我國“八(ba)縱八(ba)橫”高(gao)(gao)(gao)速(su)(su)鐵(tie)(tie)(tie)路網蘭州（西(xi)(xi)寧(ning)）至(zhi)(zhi)廣(guang)州通(tong)(tong)(tong)道的(de)(de)重要組(zu)成部(bu)(bu)分。線(xian)路在成都(dou)樞紐(niu)與西(xi)(xi)成高(gao)(gao)(gao)鐵(tie)(tie)(tie)、成渝高(gao)(gao)(gao)鐵(tie)(tie)(tie)連接，在貴(gui)陽(yang)(yang)樞紐(niu)與貴(gui)廣(guang)高(gao)(gao)(gao)鐵(tie)(tie)(tie)、滬昆高(gao)(gao)(gao)鐵(tie)(tie)(tie)連接，沿(yan)(yan)(yan)途的(de)(de)川南(nan)宜(yi)賓、滇北(bei)昭通(tong)(tong)(tong)、黔西(xi)(xi)畢節等(deng)地區(qu)結束(shu)了沒有高(gao)(gao)(gao)鐵(tie)(tie)(tie)的(de)(de)歷史，實現了成都(dou)和貴(gui)陽(yang)(yang)西(xi)(xi)南(nan)兩大(da)客運(yun)(yun)中心的(de)(de)高(gao)(gao)(gao)鐵(tie)(tie)(tie)互聯(lian)互通(tong)(tong)(tong)，完善了我國西(xi)(xi)部(bu)(bu)高(gao)(gao)(gao)速(su)(su)鐵(tie)(tie)(tie)路網結構(gou)，形成川渝黔地區(qu)通(tong)(tong)(tong)往珠三角、長三角等(deng)沿(yan)(yan)(yan)海(hai)發(fa)達地區(qu)的(de)(de)快(kuai)速(su)(su)客運(yun)(yun)通(tong)(tong)(tong)道。成貴(gui)高(gao)(gao)(gao)鐵(tie)(tie)(tie)的(de)(de)全(quan)(quan)線(xian)開(kai)通(tong)(tong)(tong)運(yun)(yun)營(ying)，將極(ji)大(da)便利沿(yan)(yan)(yan)線(xian)人民群(qun)眾(zhong)出行，暢通(tong)(tong)(tong)我國西(xi)(xi)南(nan)與東南(nan)沿(yan)(yan)(yan)海(hai)地區(qu)聯(lian)系(xi)，加快(kuai)沿(yan)(yan)(yan)線(xian)旅游和礦產資(zi)源開(kai)發(fa)，對(dui)助力脫(tuo)貧(pin)攻堅，推動西(xi)(xi)部(bu)(bu)大(da)開(kai)發(fa)戰略(lve)實施，具有十(shi)分重要的(de)(de)意義。線(xian)路全(quan)(quan)長648公里，此次開(kai)通(tong)(tong)(tong)的(de)(de)為宜(yi)賓至(zhi)(zhi)貴(gui)陽(yang)(yang)段長372公里。成都(dou)至(zhi)(zhi)樂山(shan)段已于2014年底開(kai)通(tong)(tong)(tong)運(yun)(yun)營(ying)，樂山(shan)至(zhi)(zhi)宜(yi)賓段2019年6月開(kai)通(tong)(tong)(tong)運(yun)(yun)營(ying)。全(quan)(quan)線(xian)通(tong)(tong)(tong)車后，成都(dou)與貴(gui)陽(yang)(yang)兩個(ge)省會城市最快(kuai)2小時58分可達。
從“和諧號(hao)”到“復興(xing)號(hao)”，經過十(shi)(shi)幾(ji)年的(de)快速(su)發(fa)展(zhan)，高(gao)(gao)鐵(tie)已成(cheng)為人們日(ri)常出行(xing)的(de)重要交通(tong)工(gong)具，“千里江陵一日(ri)還(huan)”早已變(bian)成(cheng)現實。高(gao)(gao)鐵(tie)不斷(duan)刷新著“中(zhong)國(guo)速(su)度(du)”，為發(fa)展(zhan)帶來新的(de)機遇。津西自2009年起生產(chan)并(bing)銷(xiao)售電氣化(hua)鐵(tie)路接觸(chu)網支柱用熱軋H型(xing)鋼(gang)，十(shi)(shi)年間不斷(duan)強化(hua)產(chan)品(pin)質量建設，實施品(pin)牌營(ying)銷(xiao)戰略，通(tong)過優質服務贏得(de)用戶青睞(lai)，與中(zhong)國(guo)中(zhong)鐵(tie)、中(zhong)國(guo)鐵(tie)建等電氣化(hua)公司形成(cheng)了(le)戰略合作伙(huo)伴關系(xi)，充分發(fa)揮(hui)專業化(hua)、系(xi)列化(hua)、規(gui)模化(hua)型(xing)鋼(gang)生產(chan)基地(di)優勢，為推動(dong)國(guo)家高(gao)(gao)鐵(tie)建設做出積極的(de)貢獻。目前，津西高(gao)(gao)鐵(tie)線(xian)(xian)(xian)(xian)(xian)桿市場占有率達90%以上，廣泛應用于京(jing)(jing)張線(xian)(xian)(xian)(xian)(xian)、京(jing)(jing)雄(xiong)線(xian)(xian)(xian)(xian)(xian)、京(jing)(jing)廣線(xian)(xian)(xian)(xian)(xian)、京(jing)(jing)滬線(xian)(xian)(xian)(xian)(xian)、哈(ha)大(da)線(xian)(xian)(xian)(xian)(xian)、滬寧(ning)線(xian)(xian)(xian)(xian)(xian)、滬杭線(xian)(xian)(xian)(xian)(xian)、滬昆線(xian)(xian)(xian)(xian)(xian)、京(jing)(jing)沈線(xian)(xian)(xian)(xian)(xian)、石(shi)濟線(xian)(xian)(xian)(xian)(xian)等國(guo)內(nei)六(liu)十(shi)(shi)余條高(gao)(gao)鐵(tie)工(gong)程。
