2. SPA-H vs. Painted/Coated Carbon Steel
| Yam | SPA-H Weathering Steel | Painted / Coated Carbon Steel |
|---|---|---|
| Kev zoo nkauj | Ntuj patina (tshwj xeeb, tsis yog -fading tom qab stabilization) | Customizable xim (xim / txheej); yooj yim tev / ploj sab nraum zoov (UV / nag puas) |
| Huab cua Resistance | Zoo heev (tus kheej- tiv thaiv patina; tsis muaj xeb hauv qab patina) | Tsis zoo (xim / txheej tev tawm ua rau xeb sai; tsuas yog luv luv -kev tiv thaiv (2-5 xyoos)) |
| Kev tu | Tsawg (ib - lub sij hawm patina tswj; tsawg kawg nkaus tu) | Siab(repaint / recoat txhua 2-3 xyoos; yuav tsum tau tshem tawm xeb ua ntej reprocessing) |
| Kev ua tau zoo | Zoo (zoo li carbon steel) | Zoo (tab sis txheej yooj yim rau kev puas tsuaj thaum txiav / vuam; xav tau -touchup) |
| Nqi | Nruab nrab-ntau yam (≈2-3x cov pa roj carbon zoo tib yam; tus nqi pib dua) | Tsawg (tus nqi pib qis tshaj ntawm cov khoom siv hlau) |
| Qhov hnyav | Ib yam (7.85g / cm³) | Ib yam (7.85g / cm³) |
| Ntsiab Scenario | Lub sij hawm ntev - kho kom zoo nkauj sab nraum zoov (tsis tu ncua) | Ib ntus / qis- pob nyiaj siv kho kom zoo nkauj sab nraum zoov (lub neej ua haujlwm luv) |
3. SPA-H vs. Aluminium Alloy (6061/5052)
| Yam | SPA-H Weathering Steel | Aluminium Alloy (6061/5052) |
|---|---|---|
| Kev zoo nkauj | Sov patina (nplua nuj kev ntxhib los mos); industrial/natural style | Nyiaj / oxidized matte tiav (lub teeb, niaj hnub style); anodized rau kev cai xim |
| Huab cua Resistance | Zoo (hauv av) / Tsis zoo (ntev ntug hiav txwv loj) | Zoo heev (txhua qhov chaw; tsim cov txheej txheem oxide nyias, tsis muaj xeb; lub teeb yuag kom zoo dua) |
| Kev tu | Tsawg (patina tswj) | Tsawg (tsis muaj xeb); txheej anodized xav tau kev tu ib ntus (tsis muaj polishing) |
| Kev ua tau zoo | Zoo (siab zog rau cov qauv loj) | Zoo heev(lub teeb yuag, yooj yim rau daim ntawv / khoov; zoo tagnrho rau ilv decorative qhov chaw) |
| Nqi | Nruab nrab-ntau yam (≈1.2-1.5x zoo tib yam aluminium alloy) | Nruab nrab-ntau yam (qis dua SPA-H; anodized aluminium siab dua) |
| Qhov hnyav | Hnyav (7.85g / cm³) | Teeb(2.7g / cm³, 1/3 ntawm SPA-H; yooj yim rau kev teeb tsa / thauj) |
| Ntsiab Scenario | Hnyav-cov khoom siv kho kom zoo nkauj (sculpture bases, loj railings) | Lub teeb ilv kho kom zoo nkauj (hollow panels, me me kos duab, facade cladding) |
4. SPA-H vs. Copper/Brass
| Yam | SPA-H Weathering Steel | Tooj / tooj dag |

| Huab cua Resistance | Zoo (hauv av) / Tsis zoo (ntev ntug hiav txwv loj) | Zoo heev (txhua qhov chaw; verdigris tus kheej- tiv thaiv; tsis muaj xeb) |
| Kev tu | Tsawg (sealer rau ntug hiav txwv) | Tsawg (tsis muaj kev saib xyuas; verdigris yog ib feem ntawm kev zoo nkauj) |
| Kev ua tau zoo | Zoo (weldable, yooj yim txiav) | Zoo (malleable, yooj yim rau forge; nyuaj rau weld rau daim loj) |
| Nqi | Nruab nrab-ntau yam (≈1/3-1/2 ntawm tooj liab) | Hwm(5-8x SPA-H; tus nqi siab) |
| Qhov hnyav | Hnyav (7.85g / cm³) | Hnyav heevtooj liab: 8.96g / cm³; tooj dag: 8.5g / cm³) |
| Ntsiab Scenario | Tus nqi - zoo nkauj patina kho kom zoo nkauj | High-kho khoom kim heev kho kom zoo nkauj (cov tsev keeb kwm, kos duab duab puab, tsim vaj tsev classic) |
