Qhov Zoo

• Lub zog siab thiab kev nruj heev ua tau: cog tseg lub zog ntau dua los yog sib luag rau ntawm 530}, elongation ntau dua los yog sib luag rau 18%, tuaj yeem tiv thaiv hnyav; Zoo heev qis-kub cuam tshuam todness (xws li S355ml tseem ruaj khov ntawm -50 degree), hloov kho mus rau ib puag ncig txias mob hnyav lossis muaj ib puag ncig txias heev.
• Zoo heev vuam thiab kev ua kev ua tau zoo: cov teeb meem carbon qis dua (xws li S355%) thiab cov kev pab cuam muaj sib luag (thiab pab txhawb kev sib tsoo tsis muaj kev sib tw ua ntej; Nto ua tiav ra tsawg dua lossis sib npaug rau 12.5μm, yooj yim rau kev txias los yog khoov, stamping thiab lwm yam txheej txheem.
• Corrosion Kuj thiab kev lag luam: muaj tooj liab, muaj lwm yam los txhim kho cov huab cua tsis kam lossis sib npaug tom qab kub}} dip galvanizing; Lub zog siab tso cai hnyav txo qis ntawm 15% -20%, txo cov khoom noj thiab tag nrho cov nqi engineering.

Cov Ntawv Thov

• Architecture thiab infrastructure: siv nyob rau hauv high {{} {} Cov nqaj ntoo loj, muab cov khoom khoov thiab cua tsis zoo. ‌
• Engineering machinery thiab tsheb: Siv thiab ua crane booms, excavator chassis txaj, trailer ntev lub neej los ntawm ntau dua 3 zaug. ‌
• Tshiab Zog thiab Cov Lus Cog Tseg Tshwj Xeeb: Siv rau Cua Fais Fab Txhawb Kev Txhawb Nqa Sab Nraws Sab Hauv, hloov pauv mus rau qhov chaw muaj kev sib txuam thiab ntev}} term loads.
