Ngokusebenziseka lula nangokuzivumelanisa nezimo, ezi tyhubhu zidlala indima ebalulekileyo kumashishini ahlukeneyo, kubandakanya ulwakhiwo kunye noomatshini.
Yintoni umahluko phakathi kwe-hollow section kunye ne-I beam?
Iinxalenye ezingenanto ziyiprofayili zesinyithi ezinengaphakathi elingenanto, ezifumaneka kwiimo ezifana nesikwere, uxande, okanye isangqa, ezisetyenziswa kakhulu ekwakheni nasekwenzeni. Zifumana amandla kwiikona zangaphandle zecandelo.Imisebe ye-IKwelinye icala, ine-cross-section efana ne-I ene-flange eqinileyo kunye ne-web. Isetyenziswa kakhulu ekwakheni, ii-I-beams zisasaza ubunzima kubude besakhiwo, zibonelela ngamandla kuyo yonke indawo. Ukukhetha phakathi kwazo kuxhomekeke kwiimfuno ezithile zesakhiwo kunye nezinto eziqwalaselwayo kuyilo.

Impendulo evela kubathengi bethu
Amacandelo angenanto adla ngokwenziwa ngeentsimbi ezifana nentsimbi, i-aluminium, kunye nee-alloys ezahlukeneyo. Olu luhlu luvumela amacandelo angenanto ukuba ahlangabezane neempawu zezinto ezifunekayo kwiiprojekthi ezahlukeneyo zobunjineli. Iimilo zejometri zamacandelo angenanto zihlala zinomtsalane ngakumbi kunoluhlu oluqinileyo, nto leyo eyenza ukuba zifaneleke kwiiprojekthi apho uyilo kunye nobuhle zizinto eziqwalaselwayo. Ngenxa yokusebenzisa kwazo izixhobo ngokufanelekileyo, amacandelo angenanto anokunciphisa inkunkuma yezixhobo, avumelane neendlela ezinobuhlobo nokusingqongileyo.
Ukupakisha:
1. Ukupakisha kubaluleke kakhulu, ingakumbi xa impahla ithunyelwa kwamanye amazwe, apho impahla idlula kwiindlela ezahlukeneyo ukuze ifikelele kwindawo efanelekileyo, ngoko ke sibeka inkxalabo ekhethekileyo malunga nokupakisha.
2. I-Saky Steel ipakisha iimpahla zethu ngeendlela ezahlukeneyo ngokusekelwe kwiimveliso. Sipakisha iimveliso zethu ngeendlela ezininzi, ezinje,
