Ho boloka likhoele ka phoso, joalo ka libakeng tse metsi, ho etsa hore mafome a be teng.
Tlhokomeliso: Tšoara likhoele ka hloko, u li hlahlobe khafetsa, 'me u li boloke ka nepo ho thibela mathata a mangata.
Khoele ea tšepe e nang le galvanized e boloka tšepe e sireletsehile mafoleng. E boetse e emisa tšenyo. Boitsebiso bona bo matla 'me bo nka nako e telele. E thusa ho boloka chelete hape.

Morero o ka sehloohong oa khoele ea tšepe e entsoeng ka masenke ke ofe?
Khoele ea tšepe e nang le galvanized e boloka tšepe e se ke ea rusa kapa ea senyeha. Lera la zinki le sebetsa joalo ka thebe. Lihahi le lifeme li e sebelisa ho etsa likarolo tse tšoarellang nako e telele le ho lula li le matla.
Ho roala zinki ho thibela mafome joang?
Zinc e kopana le metsi le moea pele tšepe e etsa joalo. Sena se etsa lera le khethehileng ka holimo. Lera le thibela metsi le moea hore li se ke tsa ama tšepe.
Ke hokae moo batho ba sebelisang khoele ea tšepe e entsoeng ka masenke hangata?
Batho ba sebelisa litšepe tse entsoeng ka masenke ho haha, ho etsa likoloi le ho etsa lisebelisoa. E ntle bakeng sa marulelo, likarolo tsa koloi le likotoana tsa mochini.
Na khoele ea tšepe e ka penta?
O ka penta galvanized tšepe coil. Bokaholimo bo hloka ho hloeka le ho omella pele. Li-primers tse khethehileng li thusa pente hore e khomarele lera la zinki.
Ke litekanyetso life tse sebetsang ho galvanized steel coil?
ASTM A653 le ISO 3575 ke melao e ka sehloohong ea li-coil tsa galvanized steel. Melao ena e bua ka hore na seaparo se teteaneng hakae, hore na bokaholimo bo shebahala joang, le hore na bo loantša mafome hantle hakae.
