Ishidi elinothayela libhekisela eshidini lensimbi elimbozwe nge-zinc futhi linokumelana okuhle nokugqwala, elikhiqizwa ngokuyinhloko inqubo yokufaka ama-hot-dip galvanizing.Eminyakeni yamuva nje, ngentuthuko esheshayo yomnotho, isidingo samashidi ensimbi ezimbonini zezimoto, ezokwakha, ezokukhiqiza kanye nesezimboni zasendlini sikhule kakhulu.Amashidi afakwe uthayela angenye yezinhlobo zensimbi ezikhula ngokushesha e-China eminyakeni yamuva.
Ungqimba lwezinki lweshidi lensimbi elicwilisiwe elishisayo linogqinsi olufanayo, ukunamathela okuqinile, aluxebuki ngesikhathi lucutshungulwa, kanye nokumelana nokugqwala okuhle.Ingaphezulu libushelelezi futhi lihlanzekile, ubukhulu bunembile, indawo yebhodi iqondile, ama-spangles alinganayo futhi amahle.
