Nruab Nrab Channel Hlau (Nruab Nrab C - channel / nruab nrab u {{1} channel)
1. Cov lus piav qhia luv luv
Nruab Nrab Channel Hlau yog c -} {{1} Daim duab zoo li qhov loj me ntawm lub teeb thiab loj / hnyav raws. Lawv muab cov kev ntsuas ntawm lub zog, txhav thiab kev lag luam txhawb nqa cov qauv ntim thiab cov khoom siv uas tsis muaj qhov hnyav lossis cov tsiaj muaj nqis.
2. Cov ntaub ntawv raug & qib
Carbon / Txheej Txheem Steel:Q235 / S235 / A36 (ib txwm muaj).
Siab dua - tawm cov xaiv:S275 / S355 / A572 GR.50 (rau qhov muaj peev xwm siab dua lossis raug txo).
HSLA / Tshwj Xeeb:S420 / S460 yog tias poob phaus lossis cov txiaj ntsig ntau dua yog qhov yuav tsum tau ua.
Corrosion / Tubrog nkoj:Huab Cua Hlau (Corten), AH36 rau nkoj / Offshore, lossis Stainless (304/316) rau kev xeb ib puag ncig.
Tiav:Zeb (xim dub), txhaj tshuaj xim dub - blast + Primer, kub}}} dip galvanize (hdg), pleev xim rau / duplexy (HDG + xim).
3. Raug geometry ranges (nruab nrab chav kawm)
Qhov tob (H):~ 120 hli → 300 hli.
Flarh Dav (B):~ 50 hli → 150 hli.
Web tuab (tw):~ 5 hli → 14 mm.
Flange Thickness (TF):~ 6 hli → 20 hli.
Nyhav rau ib meter:Feem ntau ~ 8 kg / m → ~ 60 kg / m (seem.
Ntev:Txheem zeb ntev (6 m, 12 m) los yog txiav - rau {{ntev; Spliced tus me nyuam rau ntev sau.
Qhov loj me / tes taw hnyav yuav tsum tau noj los ntawm cov xeem Seem Sib Tw (Cov Qauv Hauv Tebchaws: GB, ASSM / AISC, JIS).
4. Yuav ua li cas kwv yees ntu cheeb tsam & loj (pab cov qauv)
Koj tuaj yeem kwv yees tus ntoo khaub lig - ntu ntu (mM²) los ntawm cov qauv sib xyaw:
Thaj Tsam (MM²)≈ 2 × (b × TF) + (H - 2 × TF) × tw
Pawg ib meter meter (kg / m){{0= cheeb tsam (mM²) × 0.00785
({0.00785=ρ / 1,000,000 nrog cov hlau ntom ntom ρ ≈ 7,850 kg / mg
