FAQ
Q1: Qhov txawv ntawm ASTM A572 GR50 thiab A36 steel phaj yog dab tsi?
A572 GR50 yog HSLA micro- alloy steel nrog lub zog siab dua (345MPa) dua li A36 steel (250MPa). Nws nta qhov hnyav dua, zoo dua qis- qhov kub thiab txias thiab kev ua haujlwm vuam, haum rau hnyav- thauj khoom cov qauv, thaum A36 yog qhov tsim nyog rau lub teeb zoo tib yam- lub luag haujlwm tsim qauv.
Q2: Koj puas tuaj yeem muab kev pabcuam loj thiab kev pabcuam?
Yog lawm. Peb txhawb customized thickness, dav thiab ntev raws li tus neeg muas zaub kos duab thiab yuav tsum tau. Lub caij no, peb muab cov kev pabcuam sib sib zog nqus xws li txiav, khoov, drilling, polishing thiab xeb- pov thawj kev kho kom tau raws li ntau yam engineering thiab kev tsim khoom.
Q3: Daim ntawv pov thawj zoo thiab cov ntawv xeem twg koj tuaj yeem muab tau?
Peb tuaj yeem muab lub Hoobkas MTC (Mill Test Certificate) ua raws li ASTM tus qauv, thiab txhawb nqa thib peb -kev tshuaj xyuas los ntawm SGS, BV, TUV thiab lwm lub koom haum tso cai. Tag nrho cov khoom muaj ua tiav cov ntaub ntawv pov thawj tsim nyog los xyuas kom meej kev lis kev cai du.
Q4: Lub sij hawm xa tuaj thiab MOQ yog dab tsi?
Cov khoom me me yog nyob rau hauv Tshuag nrog 3-7 hnub xa khoom sai. Kev cai- cov khoom loj yuav siv sijhawm 10-20 hnub ua haujlwm. MOQ yog 1 tuj, thiab peb txhawb kev sib xyaw batch xaj kom tau raws li qhov kev txiav txim me me thiab cov khoom loj-batch xav tau.
Q5: Puas yog A572 GR50 steel phaj haum rau sab nraum zoov thiab qis - qhov kub thiab txias?
Yog lawm. Cov qib steel no muaj qhov zoo heev uas tsis tshua muaj - qhov kub thiab txias tsis kam thiab atmospheric corrosion kuj, kev ua haujlwm ruaj khov nyob rau hauv -20℃rau qhov kub thiab txias ib puag ncig, haum rau sab nraum zoov qhib- huab cua engineering, kev tsim kho hauv cheeb tsam txias thiab lwm yam kev ua haujlwm hnyav.
Q6: Dab tsi yog txoj kev ntim khoom koj txais rau kev xa tawm?
Peb txais cov txheej txheem export seaworthy ntim: cov ntawv tsis muaj dej tsis zoo, cov yas zaj duab xis txheej, steel siv kho, ntoo pallet lossis hlau thav duab ntim, zoo tiv thaiv ya raws, xeb thiab deformation thaum lub sij hawm ntev - kev thauj mus los hauv hiav txwv thiab av.
