Galvanized steel phaj yog welded steel phaj nrog kub-dip lossis electro galvanized txheej rau saum npoo, uas yog dav siv hauv kev tsim kho, khoom siv hauv tsev, tsheb thiab nkoj, ntim khoom, kev lag luam electromechanical, thiab lwm yam.
Txoj kev loj hlob ntawm kub dip galvanizing ntau lawm nyob rau hauv Tuam Tshoj tau lagging qab.Los ntawm 1950s mus rau 1960s, 13 flux kub-dip galvanizing units rau ib daim ntawv steel phaj tau ua tiav ua tiav, muaj peev xwm ntawm 100000 t / A. Txawm li cas los xij, vim qhov tsis zoo ntawm cov khoom siv qis, tus nqi siab, tsis zoo, ib puag ncig muaj kuab paug, tsis zoo. cov txiaj ntsig kev lag luam thiab lwm yam, lawv tau raug tso tseg thiab hloov mus rau kev tsim khoom.Los ntawm lig 1970s, Tuam Tshoj pib tsim loj-scale broadband kub-dip galvanizing units.
