Galvanized steel kavyog dav exported los ntawm Tuam Tshoj rau kev tsim kho, infrastructure, roj & roj, dej, fencing, thiab industrial daim ntaub ntawv. Rau cov neeg yuav khoom thoob ntiaj teb, kev nkag siabyuav ua li cas galvanized steel yeeb nkab nqi txiav tximNws yog ib qho tseem ceeb rau kev siv nyiaj txiag kom raug, kev sib piv tus neeg muag khoom, thiab kev sib cog lus cog lus.
Raw Khoom Nqi (Carbon Steel Base Khoom)
Qhov loj tshaj plaws ntawm galvanized steel yeeb nkab nqi yog qhovbase steel khoom.
Feem ntau cov tuam ntxhab hauv Suav teb siv cov qib carbon steel uas ua raws li cov qauv ntawm:
ASTM International (xws li ASTM A53)
European Committee rau Standardization (EN cov qauv)
Japanese Industrial Standards Committee (JIS cov qauv)
Tus nqi tsav tsheb:
Ntiaj teb no kub-rolled coil (HRC) nqi
Hlau ore thiab coking thee hloov pauv
Tuam Tshoj steel mills muab- qhov xav tau sib npaug
Qib yuav tsum tau (Q195, Q235, Q355, thiab lwm yam)
📌 Thaum cov nqi hlau nyoos nce, galvanized yeeb nkab nqi nce raws li.
Zinc Txheej Nqi (Cov txheej txheem Galvanizing)
Zinc yog ib qho tseem ceeb ntawm cov khoom siv hauv cov kav dej galvanized.
Muaj ob hom loj:
🔹 Kub-Dip Galvanized (HDG)
Kev siv zinc ntau dua
Txheej thickness feem ntau 60-120 μm
Zoo dua corrosion kuj
Tus nqi siab dua
🔹 Pre-Galvanized
Thinner txheej (8-30 μm)
Tsawg siv zinc
Tus nqi qis dua
Tus nqi tsav tsheb:
Ntiaj teb no zinc ua lag luam tus nqi
Yuav tsum tau txheej thickness (g / m² los yog μm)
Galvanizing txoj kev (post-galvanizing vs pre-galvanizing)
📌 Thicker zinc txheej=tus nqi siab dua tab sis kev pab lub neej ntev dua.
Yeeb Nkab Loj & Phab Ntsa Thickness
Cov yeeb nkab hnyav ncaj qha cuam tshuam rau tus nqi.
Cov yeeb nkab hnyav dua (txoj kab uas hla loj dua + phab ntsa tuab), qhov siab dua cov khoom siv ib 'meter'.
Tus nqi tseem ceeb Formula:
Nqe ib tuj × luj ib 'meter'=nqi ib 'meter'
Qhov ntau thiab tsawg (DN200, DN300+) thiab cov kav hlau hnyav hnyav ua rau tus nqi nce ntxiv vim kev siv hlau thiab zinc ntau dua.
Txoj kev tsim khoom
| Hom kev tsim khoom | Tus Nqi Theem | Sau ntawv |
|---|---|---|
| ERW (Electric Resistance Welded) | qis | Feem ntau rau kev tsim kho |
| Seamless | Siab dua | Siv rau siab & roj / roj |
| SAW (Submerged Arc Welded) | Nruab nrab-siab | Cov kav dej loj |
Seamless galvanized kav feem ntau kim dua cov kav dej welded.
International Standards & Certification Requirements
Kev ua raws li cov qauv thoob ntiaj teb ua kom muaj kev ruaj ntseg zoo -tab sis kuj raug nqi.
Cov qauv xa tawm feem ntau suav nrog:
ASTM A53 / A123
TS EN 10240
TS EN ISO 1461
JIS G3466
Daim ntawv pov thawj los ntawm cov koom haum xws li:
SGS SA
Bureau Veritas
Intertek
ntxiv cov nqi tshuaj xyuas tab sis txhim kho cov neeg yuav khoom kev ntseeg siab.
Order Quantity (MOQ & Volume Discounts)
Suav manufacturers muab cov nqi sib tw:
Kev txiav txim me me → siab dua ib - tuj tus nqi
Tag nrho cov thawv load (20ft / 40ft) → optimized pricing
Ntev - daim ntawv cog lus → cov nqi sib tham zoo tshaj plaws
Kev txiav txim ntim loj dua txo cov nqi tsev vim:
✔ Tus nqi tsim khoom qis dua
✔ Optimized zinc da dej efficiency
✔ Txo nqi logistics ib tuj
Ntim & Export Logistics
Export-cov nqi ntsig txog suav nrog:
Steel strapping & waterproof wrapping
Yas kawg caps
Palletizing (yog tias xav tau)
Thawv loading & inland trucking
Freight (FOB / CFR / CIF nqe lus)
Cov nqi thauj khoom hiav txwv tuaj yeem cuam tshuam tag nrho cov nqi tsaws, tshwj xeeb tshaj yog rau cov khoom siv hlau hnyav.
Exchange Rate & Trade Policy
Txij li thaum xa tawm raug nqi hauv USD, qhov hloov pauv hauv:
USD / CNY pauv tus nqi
Export se rebates
Anti- cov dej num pov tseg
Ntshuam tariffs nyob rau hauv lub teb chaws
tuaj yeem cuam tshuam ncaj qha rau cov lus kawg.
Kev Lag Luam Kev Lag Luam & Kev Xav Tau raws caij nyoog
Steel nqi nyob rau hauv Tuam Tshoj yog cyclical:
Kev tsim kho lub caij nyoog siab tshaj → nqi nce
Lub caij ntuj no slowdowns → tej zaum tus nqi softening
Infrastructure stimulus → nqi volatility
Kev soj ntsuam Suav steel yav tom ntej kev lag luam tuaj yeem pab cov neeg yuav khoom cia siab tias tus nqi sib txawv.
Summary : Tus nqi tseem ceeb ntawm cov khoom tawg
| Cov khoom siv kos duab | Kwv yees qhov cuam tshuam rau tus nqi kawg |
|---|---|
| Base Steel Khoom | 60–75% |
| Zinc Txheej | 10–20% |
| Kev tsim khoom | 5–10% |
| Daim ntawv pov thawj & Kev Xeem | 1–3% |
| Ntim & Logistics | 5–15% |
Yuav ua li cas cov neeg yuav khoom tuaj yeem tau txais tus nqi zoo tshaj
