1)waya wachitsulo woviikidwa ndi galvanized wotenthaNdi waya wa kaboni womwe umapangidwa ndi galvanized pamwamba pogwiritsa ntchito electroplating kapena hot plating. Ntchito yake ndi yofanana ndi ya waya wachitsulo wowongoka ndi wotenthetsa. Ingagwiritsidwe ntchito ngati ma tendons osalumikizidwa, koma zinc ya 200 ~ 300g iyenera kuyikidwa pa malo a mita imodzi. Nthawi zambiri imagwiritsidwa ntchito ngati chingwe cha waya chofanana cha Bridges chokhazikika pa chingwe (kuphatikiza apo, zophimba za chingwe zosinthika zimagwiritsidwanso ntchito ngati chitetezo chakunja)
