PC Galvanized (Aluminium) Strand
Cov khoom no tau thov kom nyob twj ywm cov kab hluav taws xob, cov xov hluav taws xob tseem ceeb thiab cov txheej txheem txuas ntawm cov kab hlau txuas txuas, sab nraud txuas ntawm cov choj choj thiab lwm yam kev teeb tsa ua ntej uas tsis cuam tshuam ncaj qha nrog cov tshuaj khib. peb tau koom nrog kev tsim kho ntau txoj kab loj-nyob txuas hniav hauv Suav teb. Txoj kab uas hla ntawm cov khoom no yog 12.70mm, 15.20mm, 15.70mm, 17.8mm thiab nws yog qhov qis qis ua ntej muaj kev nyuaj siab. Cov hlau hlau xaim tau txuas ntxiv thiab ruaj khov los ntawm kev kho cua sov, tom qab ntawd ua nruab nrab ua rau galvanized (txhuas) txoj hlua. Txoj hlua tsis muaj kev khi, thiab yuav tsis xoob tom qab txiav. Cov txheej saum npoo yog ib yam thiab tsis tu ncua, thiab qhov ncaj yog qhov zoo. Cov khoom siv kho tshuab ua tau raws li qhov yuav tsum tau ua ntawm ASTMA416, prEN10138, NFA35-035 thiab lwm yam txheej txheem thoob ntiaj teb. Cov hlua muaj qhov ntev sib xws, uas yog 12-16 npaug ntawm qhov taub uas muaj npe. Qhov txheej txheej ntawm ib leeg hlau yog 190 ~ 350g/m2. Cov ntsiab lus txhuas ntawm zinc-aluminium alloy steel strand txheej tsis tsawg dua 4.2%. Cov txheej txheej nplaum muaj zog, thiab txheej txheej zoo ib yam yam tsis muaj xau. Tus nqi zinc tuaj yeem ua tau raws li qhov xav tau ntawm A475-09, qib A.
