Melemo ea AR Steel?
Jindalai Steel e fana ka poleiti ea tšepe ea AR ka bongata bo boholo le bo nyane ho baqapi le basebelisi ba limela ba batlang ho lelefatsa bophelo ba ts'ebeletso ea likarolo tsa bohlokoa le ho fokotsa boima ba yuniti ka 'ngoe e kentsoeng ts'ebeletso. Melemo ea ho sebelisa poleiti ea tšepe e sa senyeheng lits'ebetsong tse kenyelletsang tšusumetso le/kapa ho thella ha lintho tse hohlang li ngata haholo.
Letlapa la tšepe le hananang le abrasion le tšoarella ka ho fetelletseng, 'me ha le senyehe, 'me le sireletsa hantle khahlanong le li-scuffs le mengoapo. Mofuta ona oa tšepe o sebetsa hantle lits'ebetsong tse thata, hape o fana ka khanyetso e itseng. Wear resistant steel plate e tla thusa ho lelefatsa bophelo ba dikopo tsa hao le ho fokotsa ditjeho tsa hao ka nako e telele.
