Ntim ntawm galvanized steel coils
Xav paub yuav ua li cas galvanized steel kauj piv rau lwm cov hlau coils (xws li txias- dov, stainless hlau)? Koj twb tuaj rau qhov zoo lawm. Raws li lub Hoobkas ncaj qha, GNEE Steel cov khoom sivgalvanized steel kauj(qib DX51D rau S350GD) thiab pab cov neeg siv khoom sib piv rau lwm txoj hauv kev. Hauv phau ntawv qhia no, peb yuav rhuav tshem qhov sib txawv ntawm kev tiv thaiv corrosion, nqi, thiab kev siv los pab koj xaiv.
Hlau coils tuaj nyob rau hauv hom xws li txias- dov (CR), kub- dov (HR), stainless hlau (SS), thiab galvanized (GI). Galvanized steel coil stands rau nws cov zinc txheej - muab kev tiv thaiv corrosion uas CR / HR tsis muaj - thaum pheej yig dua li cov hlau tsis muaj steel.
Txawm hais tias koj tab tom xaiv ntawm galvanized thiab txias - dov rau cov khoom siv los yog galvanized thiab stainless rau cov ntug dej hiav txwv, qhov kev sib piv no qhia txog qhov zoo tshaj plaws haum rau koj cov kev xav tau.

Galvanized Steel Coil vs. Txias-Rolled (CR) Steel Coil
Txias-rolled coil yog du tab sis tsis muaj corrosion kuj- ntawm no yog qhov nws piv rau galvanized:
| Qhov xwm txheej | Galvanized Steel Chev | Txias-Rolled Steel Chev | Qhov tseem ceeb Advantage rau Galvanized |
|---|---|---|---|
| Corrosion Resistance | Zoo heev (zinc txheej) | Poor (rusts yooj yim) | Tsis xav tau kev pleev xim; haum rau siv sab nraum zoov |
| Nto tiav | Smooth (Ra tsawg dua lossis sib npaug rau 1.6μm) | Zoo heev (Ra tsawg dua lossis sib npaug rau 0.8μm) | Zoo txaus rau painting; zoo dua corrosion kuj |
| Nqe (1.0mm thickness) | $710-$750/ton | $680-$720/ton | Tsuas yog 5% tus nqi siab dua rau 5x lub neej ua haujlwm ntev dua |
| Qib Muaj | DX51D, S280GD, S350GD | SPCC, PEB | Ntau qhov kev xaiv muaj zog rau kev siv cov qauv |
| Daim ntawv thov | Cov khoom siv plhaub, kab teeb | Automotive qhov chaw, rooj tog | Ntau yam siv rau sab hauv / sab nraum zoov |

Mechanical Properties Sib piv (1.0mm thickness)
| Khoom | Galvanized (DX51D) | Txias-Rolled (SPCC) |
|---|---|---|
| Yield zog (MPa) | Ntau dua lossis sib npaug rau 235 | Ntau dua lossis sib npaug li 230 |
| Tensile zog (MPa) | 315-500 | 320-420 |
| Elongation (%) | Ntau dua lossis sib npaug li 28 | Ntau tshaj los yog sib npaug rau 30 |
Galvanized Steel Chev vs Stainless Hlau (SS) Chev
Stainless hlau kauj muaj superior corrosion kuj tab sis yog kim dua - ntawm no yog qhov tawg:
| Qhov xwm txheej | Galvanized Steel Chev | Stainless hlau (304) Coil | Qhov tseem ceeb Advantage rau Galvanized |
|---|---|---|---|
| Corrosion Resistance | Zoo heev (Z275: 15-20 xyoo ntug dej hiav txwv) | Zoo heev (50+ xyoo ntug hiav txwv) | 70-80% tus nqi qis rau feem ntau daim ntawv thov |
| Nqe (1.0mm thickness) | $710-$750/ton | $2,500-$2,800/ton | Tus nqi ntau dua -zoo rau qhov tsis yog- ib puag ncig hnyav |
| Kev xaiv muaj zog | DX51D (235MPa) rau S350GD (350MPa) | 304 (205 MPa), 316 (210 MPa) | Qib siab zog rau kev siv cov qauv |
| Ua kom yooj yim | Zoo (formable, weldable) | Zoo (tab sis yuav tsum tau vuam tshwj xeeb) | Yooj yim rau txheej txheem nrog cov cuab yeej txheem |
| Daim ntawv thov | Kev tsim kho, khoom siv | Kev ua zaub mov, marine | Tus nqi zoo dua rau kev siv dav dav |

Txheej vs. Alloy Corrosion Protection
Galvanized: Zinc txheej ua raws li kev txi anode- tiv thaiv hlau txawm tias khawb.
Stainless hlau: Chromium alloy tsim ib txheej oxide passive- tsis tas yuav tsum tau txheej tab sis kim heev.
Galvanized Steel Chev vs. Kub-Rolled (HR) Steel Chev
Kub- dov kauj yog tuab thiab muaj zog tab sis muaj qhov ntxhib saum npoo- ntawm no yog qhov nws piv:
| Qhov xwm txheej | Galvanized Steel Chev | Kub-Rolled Steel Chev | Qhov tseem ceeb Advantage rau Galvanized |
|---|---|---|---|
| Nto tiav | Smooth (Ra tsawg dua lossis sib npaug rau 1.6μm) | Rough (Ra Tsawg dua lossis sib npaug li 12.5μm) | Tsis xav tau kev sib tsoo; npaj rau painting |
| Corrosion Resistance | Zoo heev | pluag | Haum rau kev siv sab nraum zoov yam tsis muaj kev kho mob ntxiv |
| Thickness Ntau | 0.3-12.0 hli | 1.5-20.0 hli | Zoo dua rau daim ntaub nyias nyias (xws li, khoom siv) |
| Formability | Zoo (khoov, stamps) | Tsis zoo (nkig thaum nyias) | Zoo dua rau cov duab complex; HR yog qhov zoo dua rau cov kab teeb tuab |
| Nqe (3.0mm thickness) | $830-$870/ton (S320GD) | $780-$820/ton | Tsuas yog 6% tus nqi siab dua rau kev tiv thaiv corrosion |
Thaum xaiv Galvanized Steel Chev
Galvanized steel kauj yog qhov kev xaiv zoo tshaj plaws yog tias:
Koj qhov project yog sab nraum zoov lossis hauv qhov chaw ntub dej (xws li kev tsim kho ntug dej hiav txwv, ntxhua khaub ncaws).
Koj xav tau qhov sib npaug ntawm lub zog, tus nqi, thiab kev tiv thaiv corrosion (tsis yog ib qho tseem ceeb).
