1, mtengo wotsika wa chithandizo: mtengo wa madzi otenthaKaboni Chitsulo cha Angle BarKupewa ndikotsika mtengo kuposa mtengo wa utoto wina;
2, yolimba: Chitsulo chopangidwa ndi chitsulo chotentha (hot-dip galvanized). Chitsulo cha ngodya chili ndi mawonekedwe a kunyezimira pamwamba, zinc wosanjikiza wofanana, palibe kutayikira kwa madzi, palibe kudontha, chomatira mwamphamvu, chokana dzimbiri mwamphamvu, m'malo okhala m'midzi, makulidwe okhazikika a dzimbiri otetezedwa ndi chitsulo chotentha amatha kusungidwa kwa zaka zoposa 50 popanda kukonza; M'mizinda kapena m'mphepete mwa nyanja, chitsulo chopangidwa ndi chitsulo chotentha chotsutsana ndi dzimbiri chimasungidwa kwa zaka 20 popanda kukonza;
3, kudalirika kwabwino:bala la ngodya yachitsulo cholimbandipo chitsulo ndi kuphatikiza kwa zitsulo, chimakhala gawo la pamwamba pa chitsulo, kotero kulimba kwa chophimbacho kumakhala kodalirika kwambiri;
4, kulimba kwa chophimbacho ndi kolimba: wosanjikiza wa galvanized umapanga kapangidwe kapadera ka zitsulo, komwe kamatha kupirira kuwonongeka kwa makina panthawi yonyamula ndikugwiritsa ntchito;
5, chitetezo chokwanira: gawo lililonse la plating likhoza kuphimbidwa ndi zinc, ngakhale m'malo otsetsereka, ngodya zakuthwa ndi malo obisika zitha kutetezedwa mokwanira;
6, sungani nthawi ndi khama: njira yopangira ma galvanizing ndi yachangu kuposa njira zina zopangira ma plaster, ndipo nthawi yofunikira yopaka utoto pamalopo mukatha kuyiyika ikhoza kupewedwa.
