Isidingo samashidi ensimbi athathiwe siye sakhula kancane kancane.

Muva nje, ngenxa yesidingo esandayo emakethe yensimbi kanye nomthelela wezinqubomgomo zokuvikela imvelo, isidingo samashidi ensimbi athathiwe siye sakhula kancane kancane.

Ishidi lensimbi eliphehliwe liwuhlobo lwensimbi oluhlanganiswe ne-zinc ukuze kuthuthukiswe ukumelana nokugqwala kwensimbi nokwelula impilo yalo yesevisi.Angeke isetshenziswe kuphela ekwakhiweni, emikhunjini, emishinini, ezimotweni, ekufakeni ifenisha yasendlini nakwezinye izinkambu, kodwa futhi ingasetshenziswa emikhakheni yamandla amasha njengamandla elanga namandla omoya.Ngokuthuthuka okusheshayo kwemboni yaseShayina, ithemba lemakethe yamashidi ensimbi liya ngokuya likhanya.

Ukuze kuhlangatshezwane nesidingo semakethe, amabhizinisi asekhaya ensimbi nensimbi akhuphule ukukhiqizwa.Kubikwa ukuthi ukukhiqizwa kwamanje kwamashidi ensimbi e-galvanized e-China sekufinyelele amathani ayizigidi ezingu-30 ngonyaka, iningi lawo asetshenziselwa ukuthunyelwa kwamanye amazwe.

Ngaphezu kwemakethe yasekhaya, izimakethe zangaphandle nazo zinesidingo esingenakushintshwa samashidi ensimbi aseShayina.Mayelana nemakethe yamazwe ngamazwe, iChina ingumkhiqizi wensimbi omkhulu kunabo bonke emhlabeni, futhi isisungule ukubambisana okubanzi kwezohwebo neYurophu, iNyakatho Melika, iNingizimu Melika, iNingizimu-mpumalanga ye-Asia nezinye izindawo.

Kodwa-ke, ekukhiqizeni amashidi ensimbi, kunezinkinga ezithile zemvelo.Isibonelo, inani elikhulu lamanzi angcolile kanye negesi engcolile kungase kukhishwe phakathi nenqubo yokukhiqiza, kubangele ukungcoliswa kwemvelo.Ngenxa yalesi sizathu, amabhizinisi asekhaya ensimbi nensimbi asabele ngenkuthalo ikhwelo likahulumeni lokuqinisa ukuvikelwa kwemvelo futhi athathe izinyathelo ezihambisana nemvelo ohlelweni lokukhiqiza ukunciphisa umthelela wazo emvelweni.

Ngesikhathi esifanayo, ngokuvela okuqhubekayo kwezinto ezintsha, amashidi ensimbi anama-galvanized nawo athuthuka njalo futhi asungula izinto ezintsha.Eminyakeni yamuva nje, ubuchwepheshe obusha bokuhlanganisa buye basetshenziswa kabanzi, njenge-hot-dip aluminium-zinc alloy layer, i-magnesium-zinc alloy layer, i-zinc-aluminium-magnesium alloy layer, njll.
