1. Zoo tshaj steel qib rau corrosion-resistant ntim
A. Txheem huab cua hlau (raug nqi, zoo rau cov mob me me)
Corten A (ASTM A242)- Cov huab cua huab cua classic, ua ib qho kev tiv thaiv patina.
Corten B (Astm A588 qib B)- Lub zog siab dua, zoo dua rau cov qauv ntim khoom.
Spa-H (Jis G3125)- Japanese Weathering hlau, muaj ntau hauv Asian-Makeers.
Zoo tshaj plaws rau:General-hom phiaj xa shipping ntim, cia units nyob rau hauv cov chaw mos ntug.
B. Txhim Kho Huab Cua Hlau (zoo dua rau cov ntug hiav txwv / cov pa ntsev)
NSGP-1 (Nippon Steel)- 3 X tau ntau dua corrosion-resistant tshaj corten hauv qab ntsev.
JFE EW-Tawv®- Muaj cov CU, CR, thiab NI rau cov tubrogrogrge.
A709 HPS 70W- Siv rau hauv cov choj tab sis haum rau cov thawv muaj zog.
Zoo tshaj plaws rau:Offshore ntim, ntug dej hiav txwv.
C. Stainless Hlau Clad lossis Coated Xaiv (Hwm Tiv Thaiv)
Aluminized Hlau (Al-Si Txheej)- Tiv thaiv ntsev thiab noo noo, siv nyob rau qee cov thawv ntim tshwj xeeb.
Stainless-Clad Hlau- Sib txuas cov tub ntxhais me me nrog cov txheej txheej txheej txheej txheej txheej txheej txheem (piv txwv li, 316L).
Kub-DIP Galvanized (HDG) + Weathering Hlau- Ntxiv kev tiv thaiv rau cov ntawv tseem ceeb.
Zoo tshaj plaws rau:Tshuaj Cia, cov tsev txwv huab ua kom huab.
2. Qhov tseem ceeb xaiv rau thawv hlau
✔ Huab cua- Nqaum? Kev lag luam? Siab vaum?
✔ Teem nyiaj- Huab cua hlau yog pheej yig dua li stainless tab sis tej zaum yuav xav tau txij nkawm nyob rau hauv cov neeg mob heev.
✔ Yuav tsum muaj zog- Corten B (A588) muaj zog dua corten a (A242).
✔ Kev nyiam ua kom zoo nkauj- xeb-nyiam patina (weathering hlau) vs. painted / galvanized saib.
