Kev tsim kho thiab kev lag luam feem ntau siv cov hlau dov hauv ntau hom hauv lawv txoj haujlwm. Nyob rau hauv cov npe ntawm cov khoom xav tau tshaj plaws, dov steel occupies tsis yog qhov kawg. Cov neeg tsim khoom muaj ntau yam ntawm hom dov hlau no.

Lawv txawv li cas, thiab xaiv cov hlau zoo li cas rau qee yam haujlwm?

Ua ntej tshaj plaws, koj yuav tsum txhais lub sijhawm, thiab tsuas yog tom qab ntawd mus rau kev xav txog cov yam ntxwv tseem ceeb thiab qhov zoo ntawm cov khoom.

Coiled steel yog nyias cov ntawv hlau nkag hauv yob. Daim ntawv dav nws txawv ntawm 200 mus rau 6000 mm. Muaj qee qhov yuav tsum tau ua rau qhov hnyav tshaj plaws ntawm ib yob. Qhov loj ntawm lub txias-kuav los tiag steel kauj tuaj yeem ncav cuag 15 tons, rau cov hlau kub dov cov duab no tsawg dua - tsuas yog 10 tons.

Rolled hlau cov khoom yog tsim nyob rau hauv ntau yam, txawm li cas los xij, kom yooj yim, txhua txoj haujlwm nthuav tawm ntawm cov khoom lag luam raug cais raws li 3 yam tseem ceeb.

• Ntog xwm txheej faib tag nrho rau hauv cov xim dub (tsis yog-pickled) coiled steel thiab pickled.
• Qhov tseebdov tuaj yeem yog qhov qub thiab siab precision.
• Ntug hom cim cov hlau tsis raug txiav thiab txiav.

Ob hom hlau no txawv ntawm hom kev tsim khoom.

Kub-dov yog raug dov thaum tseem kub. Nws cov yam ntxwv tshwj xeeb yog daim ntawv tuab ntawm 10-15 hli, qhov nruab nrab ntawm qhov smoothness thiab qhov hnav tsis tshua muaj qhov pib. Txawm li cas los xij, qhov no tsis txhais hais tias cov khoom siv no yuav tsis pom daim ntawv thov. Nws yog dav siv nyob rau hauv kev tsim khoom ntawm ntau hom profile kav.

Cold-rolled steel coils muaj qee qhov sib txawv ntawm cov qauv dhau los. Nws yog tib yam kub-kuav los tiag hlau, tab sis nrog ntxiv ua. Qhov no yog qhov tso cai rau nws kom muaj cov pa roj carbon tsawg. Cov yam ntxwv hauv kev tsim tshuab muab cov hlau txias txias thiab qee qhov haujlwm ua haujlwm:

• yam tsawg kawg nkaus thickness ncav cuag 0.45mm;
• daim ntawv saum npoo ua kom du;
• zoo rau vuam.

Qhov zoo ntawm coiled steel

Ntxiv rau cov hlau dov, cov tuam ntxhab muab cov ntawv hlau. Xav txog qhov zoo sib xws thiab qhov sib txawv ntawm cov haujlwm no, ib tus tuaj yeem pom qhov zoo ntawm cov khoom siv hauv yob.

• Yooj yim cia. Roll media yog compactly ntim thiab xav tau qhov chaw cia tsawg kawg nkaus.
• Yooj yim thauj khoom, tshem tawm thiab thauj.
• Kev ua tiav ntawm qhov sib txawv ntawm qhov dav.

Galvanized steel

Galvanized coiled steel yog hom dov hlau uas yog coated ntawm ob sab nrog ib txheej ntawm zinc thaum lub sij hawm tsim khoom. Cov yam ntxwv no txo qhov kev pheej hmoo ntawm corrosion thiab ua rau lub neej kev pab cuam ntawm cov hlau ntev.

• galvanic method;
• txoj kev kub - qhov kev xaiv no yog kev lag luam ntau dua, yog li cov khoom tiav yuav zoo dua rau tus nqi.

Qhov zoo ntawm cov tiav galvanized dov hlau yuav tsum ua raws li cov cai thiab cov qauv. Lawv raug sau tawm hauv GOST 14918-80.

polymer txheej

Pre-painted dov steel tau dhau los ua lwm txoj hauv kev rau cov khoom siv galvanized. Lub hauv paus ntawm hom dov hlau no yog galvanized steel nyob rau hauv ib lub kauj, txawm li cas los xij, qhov kev xaiv no raug suav tias yog kev txhim kho vim muaj txheej txheej polymer ntxiv.txheej nws txawv ntawm qhov sib txawv, yog li koj yuav tsum xaiv nws. noj mus rau hauv tus account qhov yuav tsum tau rau cov khoom tiav.

Polyester. Qhov kev xaiv no lav tiv thaiv xeb thiab kev hloov pauv sai sai ntawm qhov kub thiab txias, tab sis nws hloov tawm los ua lub zog tsis muaj zog hauv kev ntxhov siab thiab tawg.

Polyvinyl chloride (PVC). Cov khoom tsim los ntawm cov hlau zoo li no yog qhov txawv los ntawm cov khoom tiv thaiv corrosion, tiv thaiv kev ntxhov siab, txawm li cas los xij, UV rays thiab qhov kub thiab txias hloov yog cuam tshuam rau lawv.

Xim thiab epoxy. Nyob ntawm qib ntawm galvanized coils, xws li txheej txheej tuaj yeem siv rau ib qhosab los yog ob leeg. Lub ntsiab kom zoo dua ntawm cov xim los yog epoxy txheej yog siab corrosion kuj thiab tus nqi qis. Polyurethane. Los ntawm kev yuav cov hlau dov nrog cov txheej zoo li no, koj tuaj yeem ua tiav lub neej ntev kev pab cuam thiab kev ntseeg siab, vim tias cov txheej polyurethane tiv thaiv cov hlau los ntawm corrosion, ultraviolet hluav taws xob, kub thiab tsis tshua muaj kub thiab txhua yam kev ntxhov siab. Tus nqi ntawm qhov kev yuav khoom yuav yog qhov kev txiav txim siab ntau dua li tus nqi ntawm cov hlau coiled nrog rau lwm hom kev tiv thaiv txheej.

thaj chaw thov

Zinc-coated dov hlau yog dav siv hauv kev lag luam. Qhov no tau ua tiav vim kev hnav tsis kam, zoo nkauj zoo nkauj (tshwj xeeb tshaj yog rau cov hlau-polymer-coated), yooj yim ntawm kev teeb tsa thiab tus nqi pheej yig.

• khoom siv vov tsev. Rau vov tsev, dov steel yog suav tias yog ib qho ntawm cov khoom siv zoo tshaj plaws. Nws tsis ntshai ntawm kev sib cuag nrog cov dej noo, tuaj yeem ua haujlwm tau ntau xyoo thiab tseem pheej yig. Tsis tas li ntawd, qhov du nto tiv thaiv cov daus los ntawm kev sib sau ntawm lub ru tsev nto. Nws yog los ntawm hom dov hlau uas cov vuas hlau yog tsim.



• Nkauj. Lub zog, yooj yim ntawm kev ua thiab kev teeb tsa, kev pheej yig, zoo nkauj zoo nkauj - tag nrho cov no tsuas yog qee qhov zoo ntawm cov hlau dov rau lub tsev cladding. Nws yog tam sim no nyob rau hauv zus tau tej cov sandwich panels, hlau siding.
• Kev tsim cov khoom siv hlau tiav. Galvanized coils raug suav hais tias yog ib qho khoom siv tsim nyog rau kev tsim khoomntau lwm yam khoom, suav nrog cov khoom siv hauv tsev thiab kev lag luam.



• Kev tsim qauv ntawm engineering networks. Cov pa cua, cua tshuab thiab tso dej feem ntau yog npaj los ntawm cov ntawv nyias nyias.
• Hauv lwm lo lus, ntau lub tuam txhab kev lag luam siv cov hlau coiled, thaum xaiv cov khoom lag luam uas tsim nyog.

Hauv lwm lo lus, dov hlau yog hom khoom siv hlau uas muaj ntau yam zoo. Ua tsaug rau qhov no, nws pom daim ntawv thov hauv kev tsim kho, kev lag luam thiab ntau lwm qhov chaw.
