Ngokuguquguquka nokuguquguquka, lawa mashubhu adlala indima ebalulekile ezimbonini ezahlukahlukene, kubandakanya nezokwakha nemishini.
Uyini umehluko phakathi kwesigaba esingenalutho kanye ne-I beam?
Izingxenye ezingenalutho amaphrofayili ensimbi anengaphakathi elingenalutho, atholakala ngamajamo afana nesikwele, unxande, noma isiyingi, avame ukusetshenziswa ekwakheni nasekukhiqizeni. Athola amandla emaphethelweni angaphandle esigaba.I-imishayo, ngakolunye uhlangothi, banesiphambano esimise okwe-I esine-flange eqinile kanye newebhu. Isetshenziswa kabanzi ekwakhiweni, imishayo ye-I isakaza isisindo ngobude besakhiwo, inikeze amandla kulo lonke. Ukukhetha phakathi kwabo kuncike ezidingweni ezithile zesakhiwo kanye nokucatshangelwa kokuklama.
Amakhasimende ethu
Impendulo Evela Kubathengi Bethu
Izingxenye ezingenalutho ngokuvamile zenziwe ngezinsimbi ezifana nensimbi, i-aluminium, nama-alloys ahlukahlukene.Lokhu kwehlukahlukana kuvumela izingxenye ezingenalutho ukuthi zihlangabezane nezici ezibonakalayo ezidingekayo kumaphrojekthi wobunjiniyela ahlukene.Izimo zejometri zezingxenye ezingenalutho zivame ukuba nokukhanga kobuhle kunezingxenye eziqinile, okuzenza afanele amaphrojekthi lapho ukuklama nobuhle kucatshangelwa khona.Ngenxa yokusebenzisa kahle izinto zokwakha, izigaba ezingenalutho zinganciphisa ukumosheka kwezinsiza, zihambisane nezinqubo ezihambisana nemvelo.
Ukupakisha:
1. Ukupakisha kubaluleke kakhulu ikakhulukazi endabeni yokuthunyelwa kwamanye amazwe lapho impahla idlula eziteshini ezihlukahlukene ukuze ifike lapho kuyiwa khona, ngakho sibeka ukukhathazeka okukhethekile mayelana nokupakisha.
2. I-Saky Steel ipakisha izimpahla zethu ngezindlela eziningi ngokusekelwe emikhiqizweni. Sipakisha imikhiqizo yethu ngezindlela eziningi, njengokuthi,
