Flat-bulb steel

Flat-bulb-steel yog tus nqi zoo tshaj plaws, muaj txiaj ntsig zoo thiab kev tiv thaiv corrosion-resistant rau phaj stiffening. Cov txiaj ntsig tseem ceeb suav nrog lub zog zoo heev rau qhov hnyav piv xa cov buckling tsis kam ntawm qhov hnyav qis dua nrog cov pas nrig lossis cov ces kaum.
Cov npoo sib npaug ntawm lub tiaj-bulb-steel profile txhais tau hais tias tsis tas yuav tsum muaj ntug sib tsoo ua ntej pleev xim, txuag sijhawm thiab nyiaj txiag thaum tsim khoom. Xim degradation thiab tsim cov corrosive khib nyiab kuj txo, ua kom lub neej ua haujlwm ntev.
