Galvanized steel kauj yog steel phaj cov khoom tsim los ntawm galvanizing siv kub dov steel sawb los yog txias-kuav los tiag steel sawb raws li lub hauv paus khoom.

Cov txheej txheej galvanized tuaj yeem tiv thaiv cov phaj hlau los ntawm kev sib cuag ncaj qha nrog ib puag ncig sab nraud, yog li ua si lub luag haujlwm tiv thaiv corrosion thiab tiv thaiv xeb.

Galvanized steel kaujyog dav siv nyob rau hauv cov nram qab no teb vim lawv zoo heev anti-corrosion zog thiab ua cov khoom:

Kev tsim kho teb:   Cov galvanized steel kauj yog siv nyob rau hauv xws li lub ru tsev, phab ntsa, awnings, qhov cua ducts, thiab lwm yam. Nws zoo heev los tiv thaiv corrosion muaj peev xwm xyuas kom meej tias cov vaj tse nyob twj ywm zoo nkauj thiab ruaj rau ntev nyob rau hauv ib puag ncig hnyav.

Automobile manufacturing:galvanized steel kauj yog siv los tsim lub cev, chassis, qhov rooj thiab lwm yam khoom. Nws lub zog siab, cuam tshuam tsis kam thiab tiv thaiv corrosion ua rau lub tsheb muaj kev nyab xeeb thiab txhim khu kev qha.

Kev lag luam khoom siv hauv tsev:Cov galvanized steel kauj yog siv los tsim cov casings rau lub tub yees, tshuab ntxhua khaub ncaws, cua txias, thiab lwm yam. Nws zoo formability thiab anti-corrosion zog ua rau cov khoom siv hauv tsev zoo nkauj dua thiab ruaj khov.
Cov khoom siv sib txuas lus:Lub galvanized steel kauj yog usded nyob rau hauv xws li lub hauv paus chaw nres tsheb, yees, kav hlau txais xov, thiab lwm yam. Nws zoo heev hluav taws xob conductivity thiab anti-corrosion zog ua kom ruaj khov kev lag luam ntawm cov khoom sib txuas lus.

Galvalume steel kaujyog cov khoom siv sib xyaw coated nrog ib txheej ntawm aluminium-zinc alloy rau saum npoo ntawm steel phaj. Cov hlau no yog ua los ntawm 55% txhuas, 43% zinc thiab 2% silicon solidified ntawm qhov kub ntawm 600 ° C los ua ib lub quaternary crystal.

Galvalume steel kaujyog dav siv nyob rau hauv cov nram qab no teb vim lawv zoo heev anti-corrosion zog thiab ua cov khoom:

Kev tsim kho teb:Galvalume steel coils feem ntau yog siv hauv kev tsim cov ru tsev, phab ntsa panels, kab hlau rhuav phab ntsa thiab lwm yam ntaub ntawv. Nws zoo heev los tiv thaiv corrosion thiab kev ua haujlwm zoo nkauj ua rau lub tsev zoo nkauj dua thiab muaj lub neej ua haujlwm ntev.

Tsheb teb:Raws li qhov yuav tsum tau ua rau lub tsheb hnyav nce, galvanized sheet coils tau siv dav hauv kev tsim tsheb. Nws yog tsuas yog siv nyob rau hauv lub tsheb lub cev, compartments, thav duab thiab lwm yam, uas yuav ua tau zoo txo ​​qhov hnyav ntawm lub tsheb, txhim kho roj kev lag luam thiab txo cov pa roj carbon monoxide.

Cov khoom siv hauv tsev:Galvanized sheet coils yog cov khoom tseem ceeb rau kev tsim cov casings thiab cov txheej txheem sab hauv ntawm cov tub yees, tshuab ntxhua khaub ncaws, cua txias thiab lwm yam khoom. Nws zoo heev los tiv thaiv corrosion thiab kev ua haujlwm ua haujlwm ua rau cov khoom siv hauv tsev zoo nkauj dua hauv cov tsos thiab ntev dua hauv kev pab cuam lub neej.

Lwm thaj chaw:Galvalume coils kuj tau siv dav hauv nkoj tsim, kev lag luam petrochemical, chaw siv hluav taws xob thiab lwm yam haujlwm. Nws lub zog siab thiab corrosion kuj ua lub luag haujlwm tseem ceeb hauv cov teb no.

Qhov kev tiv thaiv corrosion ntawm galvanized ntawv coils yog 6-8 npaug ntawm cov ntawv zoo tib yam galvanized, thiab nws tuaj yeem ua kom muaj kev ua haujlwm tsis muaj xeb nyob hauv ntau qhov chaw.

Qhov no feem ntau yog los ntawm kev tiv thaiv kev ua haujlwm ntawm aluminium. Thaum lub zinc txheej, cov txheej txhuas yuav ua cov yeeb yaj kiab txhuas oxide los tiv thaiv cov tshuaj corrosive los ntawm sab hauv.

Colombia ua ntej kev txiav txim siab tiv thaiv pov tseg ntawm Suav galvanized steel kauj thiab galvalume steel kauj: 29.9% ib ntus tiv thaiv dumping lub luag haujlwm

Raws li Tuam Tshoj Trade Remedy Information Network, Lub Xya hli ntuj 19, Colombian Ministry of Trade, Industry thiab Tourism tau tshaj tawm tsab ntawv ceeb toom 204 nyob rau hauv lub official gazette, hais txog.galvanized steel kaujthiab galvanized zinc alloy coils originated nyob rau hauv Suav teb (Spanish: Lámina lisa galvanizada y galvalume y teja galvanizada y galvalume) tau txiav txim siab ua ntej los tiv thaiv dumping, uas tau them se tawm ib ntus ntawm 29.9% ntawm cov khoom lag luam koom nrog.

Qhov kev ntsuas yuav pib siv txij hnub tom qab tshaj tawm tshaj tawm hauv cov ntawv tshaj tawm thiab yuav siv tau rau rau lub hlis. Cov lej se Colombian ntawm cov khoom lag luam koom nrog yog 7210.49.00.00, 7210.61.00.00 (tsuas yog galvanized thiab galvanized zoo tib yam daim hlau), 7210.69.00.00, 7225.92.00.90, 7225.909.00, 7225.909.00, 7225.909.00. 7210.41.00.00 thiab 72 10.61

Cov dej num uas tau hais los saum toj no los tiv thaiv tsis pub siv rau galvanized corrugated sheet coils thiab galvalume-zinc corrugated sheet coils hauv qab cov khoom .00.00.

Thaum Lub Plaub Hlis 30, 2024, Colombian Ministry of Trade, Industry thiab Tourism tau tshaj tawm tsab ntawv tshaj tawm No. 115 nyob rau hauv lub official gazette, launched ib tug anti-dumping soj ntsuam rau galvanized thiab txhuas-zinc alloy phaj coils los ntawm Tuam Tshoj.
