Tupela Galvanized na Corten steel em ol strongpela na gutpela ain we i save wok gut ausait, tasol wanem samting i mekim ol i narapela kain? Na wanem samting i gutpela moa long projek bilong yu?
Ain we i save senis long taim bilong san
Ol 'weathering steel', we i gat kopa insait long en, i save kamapim wanpela 'natural iron-oxide' (rust) patina we i save stap gut taim em i kamap pinis, na i gat bikpela strong bilong sakim korosen taim yu skelim wantaim 'carbon steel'. Korosen-retarding ifek bilong protektiv leia i kamap long spesel distribusen na konsentresen bilong ol aloi element i stap. Leya we i lukautim pes bilong en i save kamap na kamap nupela gen oltaim taim weta i senisim. Long narapela tok, ol i larim ain i kamap ros bilong kamapim 'patina', o 'protective layer'.
"Corten" i makim kemikel komposesen bilong ol dispela ain, we i larim ol long soim bikpela strong bilong sakim korosen bilong win taim yumi skelim wantaim ol narapela ain.
Corten i save kamapim wanpela kala we i narakain na i luk gutpela moa long 'mild steel' sapos em i op. Taim ol i stap klostu long ol samting, 'mild steel' tu bai 'leech'.
Planti taim ol i save salim 'weathering steel' olsem wanpela "no-maintenance" 'steel' long maket bilong ol bris na haiwe stret. Tasol, long laspela sampela yia, ol hevi bilong 'weathering steel' i pasim wok bilong en. Divelopmen bilong 'rust patina' i no strong tumas na i nidim wanpela gutpela 'wet-dry cycle', na em i no save wok gut long ol ples we i gat wara o we ol diwai i save bungim ain. Maski sampela taim ol disaina i save laikim lukluk bilong ples, ol hevi bilong 'rust runoff' na 'staining' bilong ol simen as bilong ol pos na bris kolum i no gutpela na i mekim na ol i no yusim tumas ol 'weathering steel'.
Long stretim dispela hevi bilong 'rust runoff', planti ol 'fabricator' bilong nau i save yusim 'pre-'rusted' na 'sealed weathering steel'. Long rot bilong hariapim 'oxidation' insait long faktori na putim wanpela klia 'fixation coating', 'steel' i kamap long -sait wantaim wanpela 'stable patina' we bai i no inap blut i go long simen oston.
Galvanized Steel
Galvanized steel em i 'steel' we ol i bin putim wanpela 'layer' bilong wanpela 'reactive metal', planti taim 'zinc'.
Dispela i wok olsem wanpela banis long oksijen na wara na, bikpela samting, 'zinc' bai bagarap moa long 'steel'. Dispela i min olsem ain i stap aninit long en i no inap long kisim ol mak na hul insait long koting na bai i no inap ros aninit long koting olsem i save kamap wantaim peint na paura koting.
Wanpela rot bilong putim 'galvanizing' em long putim olgeta samting insait long bikpela wara bilong 'molten zinc', we i save pas long pes bilong en long wanpela tikpela hap. Bikos em i tik, ol tret, na ol narapela samting bai ol i mas haitim o stretim gen bihain long ol i putim long wara, maski ol tret we i gat bikpela -diamita i ken i gat inap 'loose tolerances' na dispela i no inap long bagarapim. Em i stat olsem wanpela lait silva kala tasol hariap em i pinis i go long wanpela grei kala.
Planti taim yu ken lukim wanpela bikpela grein straksa long ol hot-dip galvanisim hap.
Braitpela 'zinc plating' i save givim gutpela 'surface finish' winim 'hot-dip galvanizing' na planti taim ol i save yusim long ol liklik hap ain olsem ol 'fastener', 'brackets', na ol narapela samting. Dispela i save holim laitpela lukluk bilong en longpela taim na i no gat bikpela strong long ol 'dimensional tolerances' bilong ol 'threads', na ol narapela samting.
Yu ken kisim tu ol 'galvanised sheet', 'tube', na 'angle steel' olsem stok materiel, na planti taim yu save painim long ol 'fold shelf trays', na ol narapela samting. Dispela i ken gutpela moa long putim ol 'complit assemblies', tasol ol 'cut edge' na 'hole' i nidim moa proteksen long kisim wankain 'corrosion resistance'.
I gat tu ol peint we i gat 'zinc-' na 'aluminum'' na i wok wankain.
Pe bilong ol samting na pe bilong laipsaiklon (LCC)
Taim evataim yumi tingim dispela tupela samting bilong wokim ol bikpela haus, namba wan pe bilong en em i hap tasol.
Pasin bilong wokim 'galvanising' standet kabon ain em i no gat bikpela pe tumas. Tasol, salim ol bikpela, wokim ol hap i go long wanpela 'galvanizing' plent i save putim bikpela kos na 'lead time'. Sapos 'zinc coating' i pinis long ol ples we i gat planti hevi, wok mentenens i save kamap bikpela mani.
Corten steel i nidim bikpela invesmen long ol samting bikos long ol 'alloying elements' bilong en. Tasol, em i rausim olgeta 'secondary galvanizing process'. Long ol bikpela ausait infrastraksa (olsem ol bris o sola mount), Corten i save win long laipsaikel kos bikos em i no nidim wanpela mentenens oltaim long planti yia bilong yusim.
Sori: Mekim Kol
Gutpela disisen i dipen long mak bilong wokim samting na ples bilong putim:
- Go wantaim 'Galvanized Steel'long ol liklik asembli, ol komponen we i nidim strongpela 'thread tolerances', o ol straksa we ol i putim long ol ples we i gat wara oltaim.
- Go wantaim Corten Steelbilong ol bikpela infrastraksa ausait, ol projek we i hat long lukautim longpela taim, o ol disain we i tok stret long dispela 'signature architectural rust aesthetic'.
Sapos yu wok long makim ol samting bilong wanpela projek we yu laik mekim na yu laik skelim ol stretpela gret-olsem ASTM A588 'weathering steel' na 'standard HDG plates'-tim bilong mipela long Promisteel i ken givim yu ol teknikel data na ol samting yu nidim.
