Galvanized Structural Steel Qib
S280GD + Z thiab S350GD + Z Galvanized Steel yog engineered los ua ke cov qauv muaj zog thiab corrosion kuj, ua rau lawv zoo tagnrho rau ntev -lub sij hawm sab nraum zoov thiab muaj ib puag ncig.
S280GD yog ib qho muaj zog, qis- alloy structural steel uas tau siv dav hauv kev tsim kho thiab tsim khoom. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 280 MPa, nws yog qhov nyuaj txaus rau kev xav tau cov haujlwm ua haujlwm. Qhov kub-dip zinc txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv corrosion, lav kev ua haujlwm ntev. Ua tsaug rau qhov kev sib xyaw ua ke ntawm lub zog thiab kev tiv thaiv, S280GD yog qhov zoo tshaj plaws rau cov txheej txheem thav duab, vov tsev, thiab lwm yam hnyav - daim ntawv thov.
Thaum ob qib sib piv cov kev xaiv zinc txheej zoo sib xws, lawv qhov kev ua tau zoo ntawm cov tshuab ua rau cov tswv yim sib txawv.
Lub zog-rau-Qhov Ua Tau Zoo
Lub zog siab dua tso cai rau cov neeg tsim qauv kom txo cov thickness thaum tswj kev nyab xeeb, tab sis qhov zoo dua no yuav tsum sib npaug tiv thaiv kev tsim khoom nyuaj.
| Tsim Qauv | S280GD + Z | S350GD + Z |
|---|---|---|
| Lub zog - rau - qhov hnyav piv | Sib npaug | Siab |
| Thickness txo peev xwm | Nruab nrab | Qhov tseem ceeb |
| Cov qauv nruj | Nruab nrab | Siab |
| Tsim yooj | Siab | Nruab nrab |
S350GD + Z feem ntau xaiv thaumQhov hnyav txo yog qhov tseem ceeb, thaum S280GD + Z yog qhov nyiam rau cov qauv tsim qauv yooj yim.
Zinc Txheej thiab Corrosion Performance
Ob qib siv tib cov txheej txheem galvanizing, lub ntsiab lus corrosion kuj yog txiav txim siab los ntawm txheej hnyav.
| Zinc Txheej | Ib puag ncig kev pabcuam |
|---|---|
| Z100–Z140 | Nyob sab hauv tsev lossis ib puag ncig qhuav |
| Z180–Z275 | Sab nraum zoov thiab industrial raug |
Los ntawm kev tiv thaiv corrosion,S280GD + Z thiab S350GD + Z ua kom sib npaugthaum siv tib txheej txheej specification.
Nqi thiab Project Economics
Kev xaiv cov khoom siv yuav tsum xav txog tag nrho cov nqi ntawm qhov project es tsis yog tus nqi ib tuj ib leeg.
| Nqi Factor | S280GD + Z | S350GD + Z |
|---|---|---|
| Unit khoom nqi | qis | Siab dua |
| Fabrication nqi | qis | Siab dua |
| Kev siv hlau | Siab dua | qis |
| Tag nrho qhov project efficiency | ruaj khov | Optimized rau hnyav loads |
Rau ntau qhov kev tsim kho tus qauv, S280GD + Z muab tus nqi zoo heev - kev ua tau zoo sib npaug.
