Dab tsi yog qhov txawv ntawm Kub-dip Galvanized Rectangular Steel Pipe Thiab Txias-dip Galvanized Square Pipe?

Txias galvanizing=electroplating, zinc txheej yog nyias thiab yooj yim rau poob, haum rau sab hauv tsev;
Kub-dip galvanizing=dipped hauv zinc. Cov txheej zinc yog tuab, zoo ib yam, thiab tsis tshua muaj corrosion-resistant. Nws yog tsim rau sab nraum zoov, engineering, thiab sab nraum zoov qauv. Thaum muas tej yaam num, nrhiav kub -dip galvanizing, uas yog ntau zaus tsawg dua.
