Ubude bokuhanjiswa kombhobho wensimbi engenasici bubizwa ngokuba ubude obucelwe ngumsebenzisi okanye ubude bekhontrakthi.Kukho imigaqo emininzi yobude bokuhanjiswa kwinkcazo:

A. Ubude obuqhelekileyo (okwaziwa ngokuba ngubude obungaguqukiyo): Nawuphi na umbhobho wensimbi ongenasici onobude obuphakathi komlinganiselo wobude benkcazo kwaye ngaphandle kwesicelo sobude obusisigxina kuthiwa ubude obuqhelekileyo.Ngokomzekelo, imithetho yokucaciswa kwemibhobho yesakhiwo: i-hot-rolled (exotshiweyo, eyandisiweyo) ipayipi yensimbi 3000mm ~ 12000mm;umbhobho obandayo otsaliweyo (oqengqiwe) wentsimbi 2000mm ~ 10500mm.

B. Ubude bokusika-ukuya-ubude: Ubude bokusika-ubude kufuneka bube phakathi kwesikali sobude obuqhelekileyo, obucelwe kwisivumelwano A ubude obusisigxina.Nangona kunjalo, ekusebenzeni, akunakwenzeka ukuqinisekisa ukuba ubude obusisigxina bunqunywe.Ngoko ke, ixabiso lephutha elilungileyo ukuba umgaqo wobude obusisigxina uvunyelwe kwinkcazo.

C. Ubude beenyawo ezininzi: Ubude beenyawo ezininzi kufuneka bube phakathi kwesikali sobude obuqhelekileyo.Ikhontrakthi kufuneka ibonise ubude beenyawo enye kunye nokuphindaphinda kobude obupheleleyo (umzekelo, i-3000mm×3, eyi-3 yokuphindaphinda kwe-3000mm, kunye nobude obupheleleyo bu-9000mm).Ngokwesiqhelo, ubude bubonke kufuneka bongezwe ngempazamo eyi-20mm, kunye nomda wokusika kufuneka ushiywe kubude berula nganye.Ukuthatha umbhobho wesakhiwo njengomzekelo, umgaqo kukushiya isibonelelo sokusika: ububanzi bangaphandle ≤159mm ngu-5 ~ 10mm;Idayamitha engaphandle>159mm yi 10~15mm.

D. Ubude bokulinganisa: ubude bomlinganiselo wombhobho wensimbi engenasici bungaphakathi kwesikali sobude obuqhelekileyo, xa umsebenzisi ecela Xa ubude obuthile bokulinganisa bulungiswa, buya kuboniswa kwinkontileka.

Kuyabonakala ukuba ubude besikali bukhululekile kuneemfuno zobude obumiselweyo kunye nobude obuphindwe kabini, kodwa bunzima kakhulu kunobude obuqhelekileyo, obuya kuzisa ukwehla kwezinga lesivuno senkampani yokuvelisa.Ngoko ke, kunengqiqo ukuba inkampani yokuvelisa inyuse ixabiso.Ukuguquguquka kokunyuka kwexabiso ngokuqhelekileyo malunga ne-4% yexabiso lesiseko.
