Kev Tswjhwm Zoo: ISO 9001 txheej txheem; beams saib xyuas los ntawm kev ntim khoom mus rau kev thauj mus los kom ntseeg tau tias lawv ncav cuag koj li qub, ua rau qhov project tsis muaj teeb meem.
Q: Dab tsi yog cov qauv rau koj I-beams hauv Central America?
A: Peb cov I Beams tau ua raws li ASTM A36 & A572 Qib 50 uas feem ntau siv rau Central America. Peb kuj tuaj yeem muab cov khoom lag luam ua raws li cov cai hauv zos (xws li Mexico's NOM).
Q: Lub sijhawm xa khoom mus rau Panama ntev npaum li cas?
A: Lub Sijhawm Sijhawm Hiav Txwv Freight los ntawm Tianjin Chaw nres nkoj mus rau Colon Free Trade Zone 28-32 hnub wks. Kev tsim khoom thiab xa tawm tag nrho yog 45-60 hnub. Kev xa sai sai tuaj yeem npaj tau, ib yam nkaus.
Q: Koj puas pab nrog kev lis kev cai?
A: Yog lawm, peb cov kws tshaj lij kev lag luam yuav ua daim ntawv tshaj tawm kev lis kev cai, them se & tag nrho cov ntawv ua haujlwm kom paub tseeb tias kev xa khoom zoo.
