3. Cov yam ntxwv tseem ceeb

ib. Tus kheej -Kev tiv thaiv corrosion kuj

Q235NH cov kav dej txhim kho ruaj khov, xeb-zoo li patina dhau sijhawm uas inhibits oxidation ntxiv. Qhov notus kheej- kho mechanismtshem tawm qhov xav tau rau kev pleev xim ntau zaus, txo cov nqi tu lub neej txog li 50% hauv qhov chaw sab nraum zoov.

b. Structural Robustness

Nrog lub zog tawm los ntawm 235 MPa thiab lub zog tensile siab, Q235NH kav dej tiv taus huab cua huab cua thiab hnyav hnyav. Lawv cov khoom siv kho tshuab muaj zog ua kom ntev -lub sij hawm ruaj ntseg hauv cov txuas hniav, cov txheej txheem kev lag luam, thiab cov tshuab tsuas.

c. Advanced Processability

Cov hlau zoo heev formability pub rau txias dov, kub shaping, thiab laser txiav, txhawb intricate architectural designs thiab prefabricated modular systems. Nws nto tuaj yeem kho nrogkua qaub ntxuav los yog xeb-cov tshuaj tiv thaivkom ceev patina tsim los yog txhim khu kev zoo nkauj.

d. anti-kev ua haujlwm qaug zog

Q235NH qhia tau tias muaj kev tiv thaiv zoo tshaj rau kev thauj khoom cyclic, ua rau nws zoo tagnrho rau kev tsheb ciav hlau, vibrating machinery, thiab cov qauv sab nrauv. Nws lub zog qaug zog ua kom lub neej ua haujlwm ntev nyob rau hauv kev ntxhov siab dua.

e. Sustainable Design

Raws li cov khoom siv rov ua dua tshiab nrog cov pa roj carbon tsawg, Q235NH ua raws li kev coj ua vaj tsev ntsuab. Nws lub neej ntev txo cov khoom pov tseg, thaum nws cov patina ntuj txhim kho hauv nroog toj roob hauv pes nrog kev lag luam, lub sij hawm- hnub nyoog zoo nkauj .

4. Cov ntawv thov

ib. Infrastructure & Kev tsim kho
