Nhasi, mapuranga esimbi anozivikanwa zvikuru mumabasa ekuvaka. MuUnited Kingdom, semuenzaniso, 90% yezvivakwa zvine nhurikidzwa yemaindasitiri uye 70% yeakawanda nyaya maindasitiri uye zvivakwa zvekutengesa zvinoshandisa simbi yekumisikidza. Varidzi vezvivakwa, vagadziri vezvivakwa, vagadziri vezvivakwa, uye makondirakiti akasarudzika pombi yesimbi mumapurojekiti ekuvaka ekutengeserana pamusoro pezvimwe zvinhu kunyanya nekuda kwesimba rayo, kugadzirisa kushoma, uye kusimba. Kunze kwezvo, humwe humwe hunhu hwakakosha, hwakadai serunako runokatyamadza, kutaridzika kwakachena, uye kuita zvakasiyana-siyana mune zvese zvitsva uye retrofit kuvaka zviri kubatsira kusimbisa zvakasimba simbi sechinhu chesarudzo chezvikoro, zvekutengesa uye zvedzidzo mapurojekiti ekuvaka.
Gore rega rega, kune akawanda vatengi vanobva kumatunhu akasiyana kuti vatenge akasiyana maratidziro emarara simbi pombi muTianjin. Mumakore achangopfuura, nekushandiswa kwechirongwa chenyika "enda kunze" uye kudyidzana kwepasi rose kwehupfumi, Tianjin simbi pombi iri kushingaira mumusika wepasi rose uye yakaita basa rakakosha mukutengeserana kwebhizinesi repasi rose. Kusiyana nezvimwe zvivakwa zvesimbi, Tianjin galvanized simbi pombi inokurumidza kugadzirira kushandiswa kana yaunzwa. Hapana kumwe kugadzirira kwepamusoro kunodiwa, hapana kuongororwa kunotora nguva, kuwedzera pendi kana machira anodiwa. Kana chimiro chaunganidzwa, makondirakiti anogona kubva atanga nhanho inotevera yekuvaka pasina kunetsekana nezve galvanized simbi zvinhu. Kana ukasarudza galvanized pipe, unogona kudzivisa mari yekuchengetedza uye kutsiva mapaipi akaora. Nepombi ine galvanized, mapaipi ako anogona kugara kwenguva yakareba kupfuura isina galvanized, izvo zvinokuchengetera mari yakawanda mupurojekiti.
Nekuda kwesimba rakakura, kufanana, huremu huremu, nyore kushandisa, uye zvimwe zvakawanda zvinodikanwa zvivakwa, pombi yesimbi yakashandiswa zvakanyanya sepombi yesimbi mumapurojekiti akasiyana ekuvaka nhasi. Kuenzaniswa nekugadzira matanda, mutengo wekutanga wekuvaka unowanzo kudhura. Nguva refu, zvisinei, simbi inoguma ichichengetedza munhu wese mari. Kwauri muvaki, uchaona zvakachipa kukweva zvimedu nekuti zvinogadzikiswa, zvinoreva kuti makambani ekubvisa marara kazhinji haabhadharise kutora simbi yako. Kune muridzi wemba, mari inochengetwa inouya nezvinhu zvakaita sekuchengetedza uye inishuwarenzi. Mafuremu esimbi haawore, kutsemuka kana kukuvadzwa netumbuyu, uye makambani einishuwarenzi anowanzo bhadharisa mari shoma painishuwarenzi yemuridzi wemba yemafuremu esimbi pamusoro pemapuranga emapuranga.
Inopisa yakanyudzwa yakanyungudutswa yesimbi pombi yave ichinzi yakakurumbira zvakanyanya pakati pevashandisi vazhinji nhasi. Chimwe chinhu, iyo galvanization process inodzivirira simbi kubva mukukuvadzwa kunopisa kunogona kuitika panguva yekufambisa, kuiswa uye sevhisi. Iyo zinc layer pamusoro pepombi inogona kuumba chipingamupinyi chekudzivirira kune zvigadzirwa zvesimbi kuwedzera hupenyu hwebasa mumashandisirwo. Kune chimwe chinhu, iyi dhizaini zvakare inopesana nekupfeka uye kukwenya, izvo zvinoita kuti simbi itaridzike. Kuyedzwa uye zvidzidzo zvakaratidza kuti avhareji yehupenyu hwekutarisira simbi yakabatiswa inoshandiswa seyakajairwa chigadziriso zvinhu inodarika makore makumi mashanu munzvimbo yekumaruwa uye 20-25 makore kana kupfuura munzvimbo yakanyanyisa yedhorobha kana yemahombekombe. Panyaya iyi, makondirakiti anogona kushandisa chigadzirwa ichi nechivimbo muprojekiti.
