50 hli Pre Galvanized Kav Txheej Txheem Cej Luam:
Kev piav qhia:Cov kav hlau galvanized ua ntej yog ua los ntawm cov hlau galvanized uas tau coated nrog zinc ua ntej lawv raug puab ua cov kav dej. Cov zinc txheej muab kev tiv thaiv tiv thaiv xeb thiab xeb.
50 hli Pre Galvanized Kav Cov Lus Qhia Tseem Ceeb:
Txoj kab uas hla:50 hli (2 nti)
Phab ntsa tuab:Feem ntau yog li ntawm 1.0mm txog 2mm, nyob ntawm seb daim ntawv thov thiab lub zog xav tau.
Ntev:Feem ntau cov qhov ntev yog 6 meters, tab sis lawv tuaj yeem txiav raws li qhov ntev tshwj xeeb ntawm cov neeg siv khoom.
Txheej:
Txheej Zinc: Qhov tuab ntawm txheej zinc feem ntau yog li ntawm 30g / m² txog 100g / m². Cov txheej txheem no yog siv rau ob qho tib si sab hauv thiab sab nraud ntawm cov yeeb nkab.
Cov Hom Xaus:
Cov Qhov Kawg Plain: Haum rau kev vuam lossis kev sib txuas khoom siv.
Cov Qhov Kawg Uas Muaj Xov: Cov xov tuaj yeem siv tau rau cov khoom siv uas muaj xov.
Cov Qauv:
BS 1387: Cov lus qhia rau cov kav hlau thiab cov tubulars uas muaj ntsia hlau thiab cov qhov (socketed) thiab rau cov kav hlau tiaj tiaj uas tsim nyog rau kev vuam lossis rau kev ntsia hlau rau BS 21 cov yeeb nkab xov.
EN 10219: Cov khoom siv vuam txias uas ua los ntawm cov hlau tsis yog hlau thiab cov hlau zoo.
Cov Ntawv Thov Ua Ntej Galvanized Pipes:
Qauv:Siv rau scaffolding, fencing, thiab cov ntawv thov hauv cov tsev.
Cov Hluav Taws Xob:Siv los tiv thaiv cov xov hluav taws xob.
Cov Tsev Cog Khoom:Lub moj khaum rau cov tsev cog khoom thiab cov qauv ua liaj ua teb.
Rooj Tog:Cov thav duab rau cov rooj, cov rooj zaum, thiab lwm yam khoom siv rooj tog.
