Txo cov nqi tsim khoom yam tsis txo qhov zoo. Peb cov S355JR carbon steel coils ua tau raws li EN 10025-2 standards thiab khaws minimum yield strength ntawm 355 MPa.
Qhov tseem ceeb yog nyob rau hauv cov tshuaj: maximum 0.22% carbon thiab 1.60% manganese. Qhov kev sib xyaw no muab ob qhov zoo tshaj plaws:
Kev welding tsis muaj cracking txawm tias thaum kub qis li -20°C.
Lub neej ntev dua 15% hauv salt spray tests piv nrog standard carbon steel.
Xav txog qhov no: Siv peb cov coils rau warehouse frames lossis trailer beds, koj yuav txuag tau txog 12% piv nrog cov alloys kim dua. Xyoo tas los, ib tug contractor German hloov. Lawv cov lus teb? "Peb tau txais lub neej ob npaug ntawm cov khoom siv ntug dej piv nrog cov coils generic."
Peb muab ob hom surface treatments: shot-blasting rau heavy-duty structural applications thiab oiling rau kev tiv thaiv xeb thaum khaws. Lub shot-blasted finish tsim ib qho uniform anchor pattern uas txhim kho primer adhesion 40% - qhov tseem ceeb rau cov haujlwm sab nraum zoov.
Peb cov cut-to-length lines tuav cov ntev los ntawm 2m txog 12m, siv high-speed saws uas khaws precision txawm tias nrog 50-ton batches. Peb kuj muab edge rounding los tiv thaiv kev raug mob thiab kev puas cuab yeej.
Raws li ib tug manufacturer Suav uas muaj 20 xyoo kev paab hauv kev muab khoom rau foreign trade industry, peb ua haujlwm 5 rolling production lines nrog tag nrho annual production capacity 600000 tons.
Peb lub quality control laboratory siv ultrasonic testing los xyuas cov internal defects, thiab txhua coil raug kuaj 100% ua ntej tawm ntawm lub Hoobkas. Peb khaws 3,000 tons hauv stock ntawm peb lub warehouse, suav nrog thicknesses 1.5-6.0mm thiab widths 1000-1500mm. Inventory hloov tshiab sijhawm tiag tiag ntawm peb lub website, thiab kev xa khoom rau cov S355jr Carbon Steel Coil muaj hauv stock tawm hauv 72 teev - tseem ceeb rau kev ua tiav koj cov haujlwm ceev.
Orders tshaj 150 tons tau 7% discount, nrog rau free processing thiab 25% tso tus nqi ocean freight.
Ntawm no yog peb qhov kev lav: yog tias ib qho coil tsis ua tau raws li mechanical properties, peb yuav hloov nws hauv 7 hnub thiab them rov qab cov nqi freight. Peb kuj kaw tus nqi 45 hnub rau cov orders uas tau lees paub los tiv thaiv koj los ntawm kev hloov ntawm khw.
