FAQ

Q: Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab cov serrated welded grating?

A: Cov qauv thauj khoom- cov kabmob muaj peev xwm txiav txim siab feem ntau los ntawm qhov tob thiab tuab ntawm cov kabmob bar. Serrated grating muaj me me txiav rau hauv ntug sab saum toj, uas me ntsis txo qhov zoo seem modulus los ntawm kwv yees li 5% -8%. Txawm li cas los xij, qhov kev cuam tshuam tsawg kawg nkaus ntawm lub peev xwm thauj khoom yog nyob deb dhau los ntawm kev nce ntxiv hauv kev nyab xeeb thiab tiv thaiv-kev ua haujlwm hauv kev ua haujlwm sab nraum zoov, roj, lossis dej khov.

Q: Yuav ua li cas kub -dip galvanizing tiv thaiv steel grating los ntawm xeb?

A: Kub-dip galvanizing (HDG) tsim cov tshuaj tiv thaiv metallurgical ntawm hlau thiab molten zinc, ua plaub qhov sib txawv zinc- hlau alloy txheej topped nrog ntshiab zinc. Nws muab ob qho tib si lub cev tiv thaiv kev tiv thaiv oxygen / noo noo thiab kev tiv thaiv cathodic sacrificial. Txawm hais tias qhov chaw raug khawb mus rau cov hlau tsis huv, cov zinc nyob ib puag ncig nws tus kheej los tiv thaiv xeb ntawm cov hlau raug.

Q: Cov kev ntsuas dab tsi yuav tsum tau txais kom tau txais qhov tseeb CAD hais?

A: Txhawm rau xam qhov kev ua tau zoo ntawm kev thauj khoom thiab muab cov lus qhia meej, thov muab:
Khoom Qib & Nto tiav: Carbon Steel (HDG / Dub) lossis Stainless Hlau 304/316 (Acid Pickled).
