BV Qib E420 Lub cev muaj zog
Lub cev muaj zog ntawm BV Qib E420 suav nrog lub zog siab, qhov hnyav, ua haujlwm ntev, ductility thiab tsis kam tiv thaiv corrosion. Hlau, raws li peb txhua tus paub, muaj lub zog zoo txawm tias nws yog qhov hnyav. Qhov tseeb, qhov piv ntawm lub zog rau qhov hnyav rau steel yog qhov qis tshaj li lwm yam khoom siv hauv tsev muaj rau peb.
