Kev tiv thaiv siab profile: I-beams ≥800 mm tau kho nrog cov roj sib txuas thiab tau muab qhwv nrog cov ntaub qhwv ob zaug.
Kev xa khoom
Txhim khu kev xa khoom xa tuaj: Kev koom tes rau cov neeg nqa khoom zoo tshaj plaws (MSK, MSC, COSCO ect) kom muaj kev nyab xeeb shipping.
Kev Tswjhwm Zoo: ISO 9001 system; Beams tau nruj tswj los ntawm kev ntim khoom los ntawm kev thauj mus los kom ntseeg tau tias lawv tuaj txog tsis zoo, tso cai rau koj kom muaj teeb meem tsis muaj teeb meem.
Q: Dab tsi yog cov qauv rau koj I-beams hauv Central America?
A: Peb cov I Beams ua raws li ASTM A36 & A572 Qib 50 uas zoo rau Central America. Nws tseem tuaj yeem muab cov khoom lag luam uas ua tau raws li cov qauv hauv tebchaws (xws li MEXICO 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.
