Emkhakheni wokwakha nokukhiqiza, amashidi ensimbi anezinsimbi avele njengento ebalulekile ngenxa yokuqina kwawo nokumelana nokugqwala. Inqubo yokufaka uthayela, ikakhulukazi i-hot-dip galvanization, ihlanganisa ukumboza insimbi ngongqimba lwezinc ukuze kuthuthukiswe impilo ende nokusebenza kwayo. Njengoba izimboni emhlabeni wonke ziya ngokuya zamukela amashidi ensimbi, kubalulekile ukuqonda izinqubomgomo zamazwe ngamazwe kanye nezindinganiso ezilawula ukukhiqizwa nokusetshenziswa kwazo. Izinkampani ezifana ne-JINDALAI Steel Group Co., Ltd. zihamba phambili kulokhu kuguquka, ziqinisekisa ukuthi imikhiqizo yazo ihlangabezana nezidingo eziqinile zomhlaba.
Emazweni omhlaba, ukukhiqizwa kanye nokusetshenziswa kwamashidi ensimbi kungaphansi kwezinqubomgomo ezisemthethweni ezahlukahlukene ezihloselwe ukuqinisekisa ikhwalithi nokuphepha. Izinhlangano ezifana ne-International Organisation for Standardization (ISO) kanye ne-American Society for Testing and Materials (ASTM) zenze imihlahlandlela abakhiqizi okufanele bayithobele. Lawa mazinga ahlanganisa izici ezifana nobukhulu be-zinc coating, izakhiwo zensimbi zensimbi, kanye nobukhulu obuphelele bamashidi. Ukuthobela le mithetho akuqinisekisi kuphela ikhwalithi yamaphepha anamathangi kodwa futhi kuthuthukisa izinqubo zokuhweba ezinobulungiswa phakathi kwabakhiqizi emhlabeni jikelele.
Ukuhlukaniswa kwamashidi anamathani kusekelwe ngokuyinhloko endleleni yokufaka uthayela kanye nesicelo esihlosiwe. Amashidi ensimbi afakwe emanzini ashisayo athandwa kakhulu ngenxa yokumelana nokugqwala kwawo okuphakeme, atholakala ngokucwiliswa kwensimbi ku-zinc encibilikisiwe. Le ndlela iphumela ekujiyileni futhi okuhlala isikhathi eside uma kuqhathaniswa namanye amasu okugalela. Ukwengeza, amashidi anamathani angahlukaniswa ngokuqina, ububanzi, nobude bawo, enzelwe ukuhlangabezana nezidingo ezithile zephrojekthi. Ukuqonda lezi zigaba kubalulekile kubakhiqizi nakubathengi ngokufanayo, njengoba kuba nomthelela ekukhethweni kwezinto zokusebenza zezinhlelo zokusebenza ezahlukahlukene.
Uma kuziwa ekucacisweni kosayizi, amashidi ensimbi athathiwe atholakala ngebanga lobukhulu ukuze kuhlangatshezwane nezidingo ezihlukahlukene zokwakha. Osayizi abajwayelekile bahlanganisa amashidi angamafidi angu-4×8, amafidi angu-5×10, nosayizi bangokwezifiso njengokucaciswa kweklayenti ngalinye. Ugqinsi lwalawa mashidi ngokuvamile lusukela ku-0.4 mm kuya ku-3 mm, kuye ngohlelo lokusebenza. Kubalulekile kubakhiqizi abafana ne-JINDALAI Steel Group Co., Ltd. ukuthi banikeze imininingwane enembile kasayizi ukuze baqinisekise ukuthi imikhiqizo yabo ihlangabezana nezidingo zemboni yezokwakha neyokukhiqiza.
Ukusebenza kwamashidi anathayela kudlulela ngale kokusekelwa kwesakhiwo; futhi zidlala indima ebalulekile ekuthuthukiseni ukukhanga kobuhle bezakhiwo nemikhiqizo. Ukubonakala kwamashidi ensimbi anamagqabhagqabha kubonakala ngokucwebezela, okusansimbi okungase kuqhubeke ukwelashwa ngemiphumela yokubuka eyengeziwe. Le khwalithi yobuhle, ehlanganiswe nezinzuzo zokusebenza zamakhasi, iwenza abe yinketho ekhethwayo kubadwebi bezakhiwo nabakhi. Njengoba isidingo samashidi ensimbi siqhubeka sikhula, ukubambelela ezindinganisweni nezinqubomgomo zamazwe ngamazwe kuzohlala kubalulekile ekuqinisekiseni ukuthi abakhiqizi baletha imikhiqizo yezinga eliphezulu ehlangabezana nezidingo zemakethe yomhlaba wonke.
Sengiphetha, isimo sokwenziwa kwamashidi ensimbi sakhiwe izinqubomgomo nezindinganiso zamazwe ngamazwe ezibeka phambili ikhwalithi, ukuphepha, nokusebenza. Izinkampani ezifana ne-JINDALAI Steel Group Co., Ltd. zizibophezele ekuthobeleni le mithetho, ziqinisekisa ukuthi imikhiqizo yazo ayihlangani nje kuphela kodwa idlule lokho okulindelwe yimboni. Njengoba imboni yezokwakha neyokukhiqiza ithuthuka, ukubaluleka kwamashidi ensimbi ngokungangabazeki kuzoqhubeka nokukhula, kuqhutshwa ukuguquguquka kwawo kanye nokuqina kwawo ezinhlelweni ezihlukahlukene.
