Wamkelekile ukubuza malunga nempahla yethu.
Ukubambelela kwimbono yakho "yokwenza izisombululo ezikumgangatho ophezulu kunye nokwenza abahlobo nabantu abavela kwihlabathi liphela", sihlala sibeka umnqweno wabathengi ukuqala ngawo.Umbhobho wentsimbi we-A53, Asme Sa106 Low Carbon Steel Umbhobho Umthungo, Umbhobho wentsimbi ongenamthungo weSt52, Bonke oomatshini abangenisiweyo balawula ngokufanelekileyo kwaye baqinisekise ukuchaneka komatshini kwiimveliso. Ngaphandle koko, sineqela labasebenzi bolawulo olukumgangatho ophezulu kunye neengcali, abenza iimveliso ezikumgangatho ophezulu kwaye banamandla okuphuhlisa iimveliso ezintsha ukwandisa ikhaya lethu lemarike nakwamanye amazwe. Silindele ngokunyanisekileyo ukuba abathengi beze kwishishini elikhulayo kuthi sobabini.
Isishwankathelo
Isicelo
Isetyenziswa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi, intsimbi yesakhiwo sealloyi kunye nentsimbi engatyiwa ngumthungo yemibhobho yentsimbi engenamthungo yoxinzelelo oluphezulu nangaphezulu kwemibhobho yebhoyila yomphunga.
