Imoto yethu kufuneka ibe kukubonelela ngempahla esemgangathweni ngexesha elibekiweyo.
Wamkelekile ukuba undwendwele inkampani yethu, umzi-mveliso kunye nendawo yethu yokugcina apho ibonisa isitokhwe sethu esiya kuhlangabezana nolindelo lwakho. Okwangoku, kulungele ukutyelela iwebhusayithi yethu, kwaye abasebenzi bethu bokuthengisa baya kuzama konke okusemandleni abo ukukuzisa eyona nkonzo ilungileyo. Qinisekisa ukuba uqhagamshelane nathi ukuba ufuna ulwazi oluthe kratya. Injongo yethu kukunceda abathengi baqonde iinjongo zabo. Senza iinzame ezinkulu ukuphumeza le meko yokuphumelela.
Malunga carbon steel welded umbhobho, kukho poeple uhlobo ebizwa MS umbhobho, nto leyo ithetha imibhobho eyenziwe ngentsimbi ethambileyo/ephantsi carbon steel(carbon steel ukuba umxholo carbon ngaphantsi kwe 0.25%). Lo mbhobho onobubele uxhaphake kakhulu, usetyenziswa kakhulu kwisakhiwo sokwakha, i-scaffold kunye nokunye. Lo mbhobho wobubele uthambile ngokwentelekiso, awukwazi ukunyamezela ukomelela okukhulu kunye noxinzelelo, ngoko ke unokusetyenziswa kuthutho lolwelo olunoxinzelelo oluphantsi. Ngenxa yokuba olu hlobo lwentsimbi lunepropati ephantsi yomatshini, aluyi kusetyenziswa kwiukusetyenziswa Imeko enemfuno ephezulu, ke xa abantu bekhankanya umbhobho we-MS, uhlala ethetha umbhobho odityanisiweyo.
Isicelo
Isetyenziswa ikakhulu kumandla kunye noxinzelelo lwamalungu, kunye nenjongo eqhelekileyo yomphunga, amanzi, igesi kunye nemibhobho yomoya.

A Isimbuku sezi elementi zintlanu masingabi ngaphezu kwe-1.00%.
B Ngayo yonke i-0.01% yehla kwi-carbon content, umxholo we-manganese ophezulu uvumelekile ukuba unyuke ngo-0.06%, kodwa ubuninzi abukwazi ukudlula i-1.35%.
C Ukuncipha ngakunye kwe-0.01% kowona mxholo wekhabhoni uphezulu kuya kuvumela owona mxholo uphezulu wemanganese ukuba unyuke nge-0.06%, kodwa ubuninzi bungagqithi kwi-1.65%.
