Cor-Ten steel yog dab tsi?

Cor-ten ® yog ib lub npe lag luam hauv Teb Chaws Asmeskas rau ib hom atmospheric corrosion resistant steel uas feem ntau siv thaum muaj zog dua thiab cov khoom siv lub neej ntev dua. Thaum raug rau ntau yam atmospheric tej yam kev mob, cov hlau ib txwm tsim ib txheej ntawm xeb los yog tooj liab xeb. Qhov no patina yog dab tsi tiv thaiv cov khoom ntawm corrosion yav tom ntej. Raws li cor-Ten ® tau nrov dua, lwm cov mills ntau lawm pib tsim lawv tus kheej atmospheric corrosion resistant steel. Piv txwv li, ASTM tsom rau kev tsim cov kev qhia tshwj xeeb uas suav tias yog sib npaug rau COR-TEN ® hauv ntau daim ntawv thov. ASTM cov ntsiab lus sib npaug yog ASTM A588, A242, A606-4, A847, thiab A709-50W.

Qhov zoo ntawm kev siv weathering steel

Cov ntawv xov xwm Wall Street Journal sau tseg tias cov kws tsim vaj tsev niaj hnub no nyiam "qhov loj ntawm cov hlau tsis huv" rau cedar thiab wrought-hlau. Tus kws kes duab vajtse tau hais nyob rau hauv tsab xov xwm qhuas cov hlau patina zoo li thiab qhuas nws cov txiaj ntsig. Lub patina ua rau "zoo nkauj xim av tawv nqaij zoo nkauj," nws hais tias, thaum cov hlau yog "tiv thaiv cuav" thiab yuav tsum tau saib xyuas me ntsis.

Zoo li COR-10, weathering steel muaj qhov zoo dua lwm cov hlau rau cov qauv raug rau sab nraum zoov, suav nrog kev saib xyuas tsis tshua muaj, muaj zog, txhim khu kev ruaj ntseg, qhov tuab tsawg kawg nkaus, txuag nqi thiab txo sijhawm tsim kho. Tsis tas li ntawd, dhau sij hawm, xeb los ntawm cov hlau sib xyaw ua ke zoo kawg nkaus nrog lub vaj, lub tiaj nraum qaum tsev, chaw ua si thiab lwm qhov chaw sab nraum zoov. Thaum kawg, qhov zoo nkauj zoo nkauj ntawm weathering steel ua ke nrog nws lub zog, durability thiab versatility tau tso cai rau nws siv nyob rau hauv tsawg tshaj li qhov zoo tagnrho cov xwm txheej xws li pob zeb phab ntsa.

Raws li tus neeg muag khoom ntawm corten sib npaug, Central Steel Service tshwj xeeb hauv kev faib khoom tshwj xeeb corten zoo tagnrho rau kev tsim vaj tsev, kev tsim vaj tsev thiab lwm yam kev siv sab nraum zoov. Nov yog 7 txoj hauv kev los siv weathering steel hauv toj roob hauv pes tsim thiab chaw sab nraum zoov:

Retaining phab ntsa

cog lub thawv

laj kab thiab rooj vag

Ntses taub ntswg ntev

Roofing thiab siding
