DX52D steel yog dab tsi?
A: DX52D yog kub-dip galvanized txias- ua hlau raws li tau teev tseg hauv European tus qauv EN 10346. "DX" sawv cev rau qib sib sib zog nqus-kos duab qib, "52" yog qib tsim, thiab "D" qhia tias kub-dip galvanizing. Nws belongs rau qis- carbon steel, thiab nws cov txiaj ntsig tseem ceeb yog cov khoom siv siab thiab galvanized corrosion kuj, ua rau nws tsim nyog rau kev ua haujlwm txias- ua haujlwm hauv kev tsim kho.
Dab tsi yog tus qauv tseem ceeb rau DX52D?
A: Tus qauv tseem ceeb yog EN 10346: 2015 "Nruam kub-dip galvanized steel sawb / ntawv - Kev xa khoom raws li txoj cai"; domestically, GB/T 2518 (Nruam kub-dip galvanized steel ntawv thiab sawb) feem ntau ua raws.
Dab tsi yog "D" hauv DX52D sawv cev?
A: "D" yog hais txog kub-dip galvanized txheej. Cov ntsiab lus feem ntau suav nrog + Z ( zinc ntshiab), + ZF (zinc - hlau alloy), thiab + ZA (zinc - aluminium alloy). Hauv kev tsim kho, DX52D + Z feem ntau siv.
Puas yog DX52D cov qauv hlau lossis cov hlau thaiv? A: Feem ntau yog siv rau cov ntaub thaiv npog / tsis yog- thauj khoom- cov kabmob (ru tsev vaj huam sib luag, phab ntsa vaj huam sib luag, cua ducts); Nws tsuas yog siv tau rau cov khoom sib txuas ntawm lub teeb steel qauv (purlins, joists), thiab tsis tuaj yeem hloov cov khoom thauj -cov kabmob steel (xws li Q235, Q355).
DX52D yog dab tsi?
A: Feem ntau galvanized coils thiab nplooj ntawv, thickness 0.5-3.0mm, dav Tsawg dua los yog sib npaug rau 1520mm; tuaj yeem ua tiav rau hauv cov ntawv profiled, C / Z- zoo li cov hlau, cov pa cua, cov menyuam kaw, thiab lwm yam khoom tiav.
