FAQ
Q1: Dab tsi yog qhov txawv ntawm S355J2H thiab S355JR square raj?
Qhov sib txawv tseem ceeb nyob rau hauv qis -kub toughness. S355JR tsuas yog txhawb nqa chav- qhov ntsuas kub ntawm qhov ntsuas kub, thaum S355J2H dhau -20℃qis- qhov ntsuas kub ntawm qhov ntsuas kub, nrog kev tiv thaiv kev tawg zoo dua. Nws yog qhov tsim nyog rau cov cheeb tsam txias, cov qauv thauj khoom dynamic thiab siab -txoj haujlwm kev nyab xeeb.
Q2: Koj puas tuaj yeem muab qhov ntau thiab tsawg thiab kho -ntev txiav?
Yog lawm. Peb txhawb kev cai phab ntsa thickness, square loj thiab ruaj -ntev txiav raws li cov neeg siv khoom kos duab thiab cov cai. Tsis yog- qhov loj me thiab cov kev pabcuam tshwjxeeb (drilling, dabtsi yog khoov, galvanizing) yog txhua yam muaj.
Q3: Cov ntawv pov thawj zoo dab tsi koj tuaj yeem muab tau?
Peb tuaj yeem muab daim ntawv pov thawj Mill Test (MTC), CE daim ntawv pov thawj, ISO 9001 daim ntawv pov thawj zoo, daim ntawv pov thawj ntawm keeb kwm thiab lwm yam ntaub ntawv kom tau raws li kev sib tw thoob ntiaj teb engineering thiab kev lis kev cai.
Q4: Puas yog S355J2H square raj haum rau qhov chaw sab nraum zoov thiab ntub dej?
Tus thawj dub tiav raj muaj qhov yooj yim xeb kuj. Rau ntev - siv sab nraum zoov thiab ntub ib puag ncig, peb pom zoo kom kub -dip galvanizing lossis los tiv thaiv- kev kho xim pleev xim rau kom ntev kev pab cuam lub neej thiab txhim kho corrosion kuj.
Q5: Koj qhov kev txiav txim yam tsawg kawg nkaus (MOQ) yog dab tsi?
Qhov ntau thiab tsawg txhawb kev txiav txim me me (1 pob). Customized ntau thiab tsawg muaj MOQ hloov tau raws li cov lus qhia tshwj xeeb. Peb txhawb nqa ob qho tib si lag luam wholesale thiab muag khoom kom tau raws li cov neeg siv khoom sib txawv.
Q6: Yuav ua li cas kom ntseeg tau cov khoom zoo sib xws?
Tag nrho cov khoom yog tsim raws li nruj raws li EN 10210 tus qauv. Peb ua kev soj ntsuam tag nrho ntawm qhov loj me, cov khoom siv kho tshuab thiab tshuaj lom neeg muaj pes tsawg leeg ua ntej xa khoom, nrog rau kev kuaj batch kom paub tseeb tias cov khoom ruaj khov thiab zoo ib yam.
