I-Royal Steel Group isebenzisa izixazululo zokupakisha ezijwayelekile zokuthumela kwamanye amazwe ukuvikela imikhiqizo ngesikhathi sokuthuthwa ibanga elide. Zonke izinto zensimbi zihlanganiswe ngokuqinile ngemichilo yensimbi futhi zigoqwe ngezendlalelo ezingangeni manzi ukuze kugwenywe umonakalo, ukuguquka kanye nomswakama. Siphinde sinikeze izinsizakalo zokulayisha eziphephile kanye nokufaka uphawu lobuchwepheshe ngokwezifiso ezilungiselelwe izidingo zamakhasimende.
Ukuze kuhlangatshezwane nomthamo wephrojekthi ohlukene kanye nezidingo zokulethwa, sinikeza ezinye izindlela zokuthumela eziguquguqukayo, okuhlanganisa ukuthunyelwa kwemithwalo egcwele (i-FCL) kanye nokulethwa kwemithwalo eminingi. Kumaphrojekthi amakhulu futhi ayinkimbinkimbi obunjiniyela, siphinde sinikeze izixazululo zokuhamba ezenzelwe wena ukuze kuqinisekiswe ukulethwa okuphephile nokufika ngesikhathi emhlabeni jikelele.
Umbuzo 1: Yimiphi imininingwane esebenza ku-akhawunti yakhoIsiteshi se-C sesakhiwo?
Zonke iziteshi zethu ze-C ezakhiwe zakhiwe ngokuhambisana ngokugcwele nezindinganiso ze-ASTM A36, okuqinisekisa ukusebenza kahle kwemishini kwamaphrojekthi okwakha omhlaba wonke.
