Dab tsi yog cov khoom ntawm S250GD + Z Hlau Chev?
S250Gd + Z yog ib nrab ntawm cov hlau nruab nrab uas yuav siv sij hawm rau hauv tus account lub zog, thiab haum rau feem ntau cov qauv hauv cheeb tsam.
Cov khoom siv hauv paus ntawm S250GD + Z Galvanized Steel Chev yog cov neeg hlau tsis muaj zog (Zn-} S250Gd + Z yog galvanized steel qib hauv lubEuropean txheem en 10346. Lub ntsiab lus ntawm txhua qhov code yog:
S: Txheej txheem hlau
250: Yam tsawg kawg vim li cas lub zog (250 MPA)
GD: Kub-Dip Galvanizing (Cov Khoom Muag General)

Dab tsi yog qhov zoo ntawm S250GD + Z Hlau Chev?
Verstility Verstility
Haum rau cov txheej txheem sib xyaw nrog nruab nrab lub zog yuav tsum tau ua, ntsuas tus nqi thiab kev ua haujlwm .
Lub galvanized txheej muab cov kev tiv thaiv corrosion (Z140 tsis muaj xeb liab tom qab 500 teev ntawm ntsev tshuaj ntsuam) .
Zoo tau zoo heev
Siab elongation (ntau dua los yog sib npaug rau 22%) yog haum rau dov, khoov, khoov thiab lwm yam ua.
Txo 15% rov qab los piv rau cov hlau siab (xws li S350GD + Z) .
③ Tus nqi siab-ua tau zoo
Tus nqi yog hais txog 20% qis dua S350Gd + Z thiab 60% qis dua aluminium {}}
