Pre - galvanized steel square yeeb: high - ua tau daws rau kev ua haujlwm thoob ntiaj teb engineering

Raws li cov khoom siv tseem ceeb hauv kev tsim kho thiab kev tsim khoom, ua ntej - kev xaiv square tubs tau dhau los ua lawv cov kev ua tau zoo, ntau yam kev siv. Peb lub tuam txhab qhia cov khoom lag luam no los muab kev ntseeg siab thiab raug nqi - Cov kev daws teeb meem rau engineering rau engineering rau engineering cov haujlwm thoob ntiaj teb.

Cov khoom no muaj peb qhov kev ua tau zoo. Firstly {{-}} Cov txheej kub txuas ntxiv:}}}}}}}}} 120 tus qauv oo-1461 tus qauv. Lub ntsev tshuaj tshuaj ntsev tshaj li 500 teev, muaj peev xwm nrog nrog cov huab cua hnyav xws li cov nroj tsuag hnyav thiab cov nroj tsuag tshuaj lom neeg, ua kom muaj kev siv ntev. Qhov thib ob, loj- teev zoo tswj: ua los ntawm high-zog q235 / q345b carbon hlau nrog ib tug cog lus muaj zog ntawm 235-345mpa. Txhua lub batch undergoes undergoes tshuab kev ua ntsuas thiab cov tsos tshuaj xyuas kom ntseeg tau tias kev sib txawv ntawm lub raj yog ± 0.2 hli. Thib peb, saj zawg zog ntau muaj peev xwm ua tau kom tau sib ntsib ntau yam, siv tshuab tsim cov thav duab, tsev neeg tsheb thauj khoom, thiab lwm yam kev tiv thaiv tsheb khiav.

Hais txog cov lus qhia tshwj xeeb, nws tau muab tag nrho cov uas hla: Cov kev cai ntev thiab tsis {[{8} Txheem Cov qauv ntau lawm tsuas yog 7 hnub, sib ntsib cov kev hloov kho ceev thiab cov haujlwm tshwj xeeb ntawm cov haujlwm loj.

Yog xav paub ntxiv, thov mus saib peb lub vev xaib lossis tiv tauj peb pab pawg muag khoom. Peb cia siab tias yuav pab koj nrog koj txoj haujlwm tom ntej.
