Ukuthengiswa okuqondile kwasefekthri kwamashubhu eyisikwele se-galvanized carbon steel
Amashubhu ayisikwele yigama lamashubhu ayisikwele namashubhu awunxande, okungukuthi, amashubhu ensimbi anobude obuhlangothini obulinganayo nobungalingani. Zenziwa nge-rolling strip steel ngemva kokucubungula. Ngokuvamile, insimbi ye-strip iyapakishwa, isicaba, igoqwe, bese ishiselwa ukuze yakhe ishubhu eliyindilinga, elibe seligoqwa libe yishubhu lesikwele bese lisikwa libe ubude obudingekayo.

Isingeniso Somkhiqizo
Eyaziwa nangokuthi insimbi egobile egobile eyisikwele nonxande, ebizwa ngokuthi amashubhu ayisikwele namashubhu awunxande, namakhodi F kanye no-J ngokulandelanayo.
1. Ukuchezuka okuvumelekile kokuqina kodonga lweshubhu yesikwele akumele kudlule ukuhlanganisa noma kususe u-10% wogqinsi oluvamile lodonga lapho ukujiya kodonga kungengaphezu kuka-10mm, kanye nokuhlanganisa noma khipha u-8% wogqinsi lodonga lapho ukujiya kodonga mkhulu kuno-10mm, ngaphandle kokuqina kodonga lwamakhona nezindawo zokushisela.
2. Ubude obujwayelekile bokulethwa kweshubhu yesikwele buyi-4000mm-12000mm, kanti u-6000mm no-12000mm yibona obuvame kakhulu. Amashubhu ayisikwele avunyelwe ukulethwa ngobude obufushane kanye nobude obungaguquki obungekho ngaphansi kuka-2000mm. Angaphinde alethwe ngendlela yamashubhu esixhumi esibonakalayo, kodwa amashubhu esixhumi esibonakalayo kufanele anqanyulwe lapho esetshenziswa umthengi. Isisindo sobude obufushane kanye nemikhiqizo yobude obungaguquki akumele seqe u-5% wevolumu ephelele yokulethwa. Kumashubhu ayisikwele anesisindo sethiyori esikhulu kuno-20kg/m, akumele eqe u-10% wevolumu ephelele yokulethwa.
3. Ukugoba kweshubhu yesikwele akufanele kudlule ku-2mm imitha ngayinye, futhi ukugoba okuphelele akufanele kudlule u-0.2% wabo bonke ubude.
