Eminyakeni yakamuva,uthango lwensimbi olwakhiwesekusetshenziswe kakhulu ekuphileni kwansuku zonke, njengocingo lwensimbi, ama-railings ezitebhisini nama-balcony railings. Lapho bebuka ubuhle bothango lwensimbi, abantu bakholelwa ukuthi abantu abaningi basenezinkinga ezithile, ingabe bakhathazekile ngokuthi uthango lwensimbi luzogqwala maduze?
Ngokombono, ngokuhamba kwesikhathi, uthango lwensimbi luvame ukugqwala ngaphansi kwethonya lendawo yesikhathi eside yangaphandle. Ngokuya ngemvelo, isikhathi sokuqala kokugqwala siyahlukahluka. Kodwa-ke, sinendlela yokuyeka ukubhekana nenkinga yokugqwala kwama-iron art guardrails. Sivame ukukhuluma ngokwelashwa kokugqwala kwemikhiqizo yobuciko bensimbi.
Kuyasiza futhi ukukhetha ukwelashwa okuvame ukusetshenziswa kakhulu kwe-hot-dip galvanizing yensimbi ezicijile. Ukuze kuthuthukiswe ikhono lokulwa nokugqwala lemikhiqizo yensimbi, abakhiqizi nabo banochungechunge lwezinqubo zokwelashwa ezingaphezulu njengokucosha kanye ne-phosphating ngaphambi kokufakwa kwe-hot-dip galvanizing. Ngesikhathi esifanayo, i-hot-dip galvanizing isebenzisa inqubo yokufaka i-hot-dip galvanizing iyonke, okuyiyo yonke i-hot-dip galvanizing ngemva kokuqedwa kokuhlanganiswa nokushisela komkhiqizo, okungagwema ngempumelelo ukugqwala kwendawo yokushisela. Ngemva kokuqeda ukugqugquzelwa kwe-hot-dip, umdwebo wangaphandle noma umuthi wokufafaza nge-electrostatic kufanele umiswe, ukuze imikhiqizo yethu ikwazi ukuthuthukisa ukulwa nokugqwala ngenkathi yethula imikhiqizo yensimbi yemibala ehlukene.
