Pombi yesimbi ine mashandisirwo akasiyana-siyana nhasi nekuda kwezvakanaka mumapurojekiti, senge 1) mutengo wakaderera wekutanga, 2) kuchengetedza kushoma, 3) hupenyu hurefu hwebasa, 4) nyore kushandisa uye saka zvese.
Mumashandisirwo anoshanda, pombi yesimbi yakatenderedza uye sikweya simbi pombi inowanzoonekwa seimwe yezvinhu zvakakosha zvekuvaka mukutengeserana kwekuvaka. Kana zvasvika kumapurojekiti ekuvaka, machubhu esimbi anoshandiswa mumhando dzakawanda dzekuvaka kubva kudiki dzekuchengetera kusvika kune skyscrapers mumaguta makuru. Semuenzaniso, ivo vanoshandiswa kugadzira hwaro hwezvivakwa zvakakura pamwe chete nehumwe hwaro. Pamusoro pezvo, rectangular simbi pombi imwe yakakurumbira nhengo yehollow chikamu mapaipi ayo ari simbi profiles ane sikweya kana rectangular chubhu chikamu. Rectangular hollow zvikamu zvinotonhora zvakaumbwa uye zvakasungwa kubva kune inopisa yakakungurutswa, inotonhora yakakungurutswa, pre-galvanized kana Stainless simbi. ASTM A500 ndiyo yakajairika simbi yekumisikidza kune hollow chimiro chikamu chinoshandiswa zvakanyanya mukuvaka nhasi.
Nhasi, China hollow chikamu machubhu anopawo zvakanakira kudzivirira ngura mumashandisirwo. Zvimwe zvikamu zvisina mhango zvine makona akatenderedzwa zvichikonzera dziviriro iri nani pane iyo ine makona akapinza. Zvichienzaniswa nezvimwe zvinhu zvechinyakare zvekuvakisa, simbi yekuumbwa yakasimba nekuti yakawedzera kusimudzirwa nesimbi yekusimbisa maitiro. Kuwedzera kwesimba rayo rakakura kudarika simba rose rezvimwe zvinhu zvinokwikwidza zvakasimba. Inopisa yakanyudzwa yakanyungudutswa yesimbi pombi yave ichinzi yakakurumbira zvakanyanya pakati pevashandisi vazhinji nhasi. Kune 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.
Pre galvanized simbi pombi ndiyo imwe yakakurumbira mhando yepombi yesimbi pamusika nhasi, iyo yakave nemarara ichiri mupepa fomati, nekudaro isati yaenderera mberi kugadzira. Pre-galvanization inozivikanwawo seguyo galvanized, nekuda kwekuti simbi inokungurutswa kuburikidza neyakanyungudutswa zinc. Mushure mekunge bepa ratumirwa nepaguyo kuti rive nemarara rinochekwa kusvika pakukura rodzokororwa. Ukobvu chaihwo hunoiswa pabepa rese, semuenzaniso pre-galvanized Z275 simbi ine 275g per square metre zinc coating. Imwe yezvakanakira iyo pre-galvanized simbi ine pamusoro inopisa dip galvanized simbi ndeyekuti ine chitarisiko chiri nani.
