Peb C steel galvanized purlins feem ntau yog siv rau lub ru tsev thiab phab ntsa txhawb nqa hauv cov tsev steel qauv. Kho los ntawm kub-dip galvanization, lawv muaj cov khoom zoo heev los tiv thaiv- corrosion thiab tsim nyog rau cov chaw tsim kho uas yuav tsum tau ua kom ntev - lub sij hawm corrosion kuj, tshwj xeeb tshaj yog siab - av noo thiab hnyav corrosive ib puag ncig. Tsis tas li ntawd, lawv tau siv dav hauv ntau yam kev tsim kho, suav nrog lub ru tsev txhawb nqa rau kev cob qhia steel thiab warehouses, nrog rau cov choj sib sib zog nqus, canopies thiab lwm yam corrosion-cov qauv tiv thaiv.
Peb muab cov dub los yog galvanized seem txiav rau koj qhov layout, ua ntej - punched rau koj daim duab, thiab bundled thiab sau npe los ntawm pab pawg ua ntej thauj khoom los ntawm ib qho chaw nres nkoj. Nyob ib ncig ntawm tus tswvcuab peb kuj muab ntau- nqes nqi ntawm cov ntaub ntawv, thiab ib txoj kab engineering uas lees paub seem, qib thiab qhov tawm tsam koj daim duab kos thiab xa rov qab nqe lus hauv 24 teev.
Engineering Performance & Design Notes
Ob yam txiav txim siab yuav ua li cas lub hauv paus- theem kev txhawb nqa cov tswv cuab coj tus cwj pwm.
Ua ntej, seem geometry.Ib qho txias - tsim C faib thauj khoom raws nws lub vev xaib thiab ob lub flanges, thiab nws qhov hnyav me me ua rau cov neeg tuag ntawm cov khoom txhawb nqa me me - qhov tseem ceeb qhov twg tus ncej hangs tawm ntawm lub formwork los yog lub hauv paus txaj.
Thib ob, kev tiv thaiv corrosion.Vim tias cov tswv cuab no zaum qis, feem ntau nyob ze ntawm cov av ntub dej, sawv ntsug dej los yog kho cov pob zeb, kub -dip galvanizing ntxiv cov zinc txheej txheej uas tiv thaiv cov ntu ntev tom qab cov neeg pleev xim rau yuav pom ntug xeb.
Cov seem raug tshuaj xyuas raws li tus qauv tswj hwm (raws li ASTM / DIN / JIS / BS spec nominated ntawm koj daim duab) rau dabtsi yog khoov, deflection thiab web crippling ntawm cov ntsiab lus txhawb, thiab phab ntsa thickness yog xaiv kom haum rau cov kev pab cuam es tsis tshaj - qhia.

FAQ:
Puas yog qhov galvanizing tiag tiag kub -dip?
Yog - galvanized cov tswv cuab yog dipped rau ntawm ib tug tshwj xeeb tus khub kub-dip galvanizing kab, muab tag nrho cov kev pab cuam nrog rau txiav ntug thiab ces kaum; cov tswv cuab dub hla cov kauj ruam no.
Cov channel no puas tuaj yeem txiav thiab drilled ntawm qhov chaw?
Lawv raug muab txiav rau koj qhov kev teeb tsa, tab sis qhov ntev ntev thiab cov tswvcuab dawb (unpunched) muaj yog tias koj qhov chaw nyiam txiav thiab laum rau hauv qhov chaw.
Cov tswv cuab galvanized puas tuaj yeem welded?
Yog lawm, tab sis weld tsuas yog nyob rau hauv qhov chaw cua - galvanizing fumes yog teeb meem - thiab txhuam cov weld thiab tshav kub- cuam tshuam cheeb tsam nrog zinc- nplua nuj xim tom qab, vim welding burns zinc hauv zos. Rau cov pob qij txha bolted koj tsuas yog kov txhua qhov chaw sau los yog rubbed.
Dab tsi yog qhov ntev tshaj plaws ib leeg muaj?
Cov tswv cuab raug txiav rau hauv lub thawv - tus phooj ywg ntev - txog li 6 m ntawm 20 ft thiab 12 m ntawm 40 ft thawv - yog li txhua qhov kev khiav tuaj txog raws li qhov ntev tau npaj tseg.
Kuv yuav qhia meej npaum li cas zinc kuv xav tau?
Zinc feem ntau teev los ntawm tus qauv galvanizing (xws li ISO 1461 / GB / T 13912) lossis raws li txheej txheej hauv g / m². Rau qhov chaw ntub dej lossis txaws kev pabcuam peb yuav taw tes rau qhov kawg siab dua ntawm cov qauv ntau; qhia rau peb ib puag ncig thiab peb paub meej tias ib chav kawm tsim nyog.
