Yuav ua li cas h - steel ua nyob rau hauv high-}} tpity ib puag ncig?
Nyob rau hauv high - av noo chaw (piv txwv li cov av noo noo), h} Tus kav dej hiav txwvKev tiv thaiv kev tiv thaivyog qhov tseem ceeb. Kub {- dip galvanizing (zinc txheej) ua rau muaj kev sib cav, kev pabcuam txuas ntxiv lub neej rau 20- 30 xyoo. Epoxy Pleev xim (ob lub tsho tiv no) kuj tseem tiv thaiv noo noo, zoo tagnrho rau sab hauv av (piv txwv li, chaw muag khoom tauj khw). Rau cov av noo heev (xws li dej nag), huab cua cov hlau qib (piv txwv li Q355Nh) tsim cov kev tsim muaj xeb ruaj khov ntxiv, tshem tawm cov kev xav tau ntawm cov txheej txheej. Lub tso dej kom zoo ib ncig ntawm H-steel qauv (piv txwv li, tsis txhob tso dej pas dej ze ntawm cov hauv paus) kuj tseem txo cov dej noo, kom ua tau zoo sib xws.
Dab tsi yog qhov hnyav tshaj ntawm h - cov nqaj hlau, thiab nws cuam tshuam li cas?
H - hnyav nyhav sib txawv los ntawm qhov loj me: × 100 × 30) hnyav ~ 350kg / m. Qhov hnyav fittated daim ntawv thov:Kev sib yuav h - steel(Tsawg dua lossis sib npaug rau 50kg / m) yog siv rau cov ntawv sau, thiab cov khw muag khoom sab hauvNruab nrab - hnyav} hnyav h - steel(50-150kg / m) Lub tsev lag luam uas ua lag luam (chaw ua haujlwm plag tsev, chaw muag khoom khw muag khoom) thiab txuas hniav me me, ntsuas qhov ntsuas thiab thauj tau kom yooj yim.Hnyav Hnyav H-} steel (>150kg / m) yog rau cov phiaj xwm kev lag luam (crane khiav, fais fab cog thav duab, xav tau hnyav {} Dost Cranes rau kev teeb tsa. Qhov hnyav tseem cuam tshuam tus nqi raug nqi siv cov nqi ntau dua hauv cov ntaub ntawv thiab thauj khoom, yog li engineers xaiv qhov hnyav tshaj plaws rau cov peev nyiaj kho.
Dab tsi yog qhov tsawg kawg thiab qhov ntev tshaj plaws ntawm h - steel ci rau kev tsim kho?
H - Cov nqaj hlau ntev yog hloov tau tab sis muaj cov qauv ntev yog 6m, 9m, 12m, thiab 15m rau kev thauj khoom yooj yim (haum feem ntau thauj khoom). TusYam tsawg kawg nkaus siv tau ntevYog 3M (siv rau cov ntawv teev cov nplaim xwm me lossis cov kev txhawb nqa theem nrab).

Ntev xaiv yog nyob ntawm Project ntev, kev txwv kev thauj khoom, thiab muaj peev xwm installation.
Yuav ua li cas h - cov hlau txo cov kev tsim khib piv rau lwm cov hlau?
