Ordinary Channel Steel
Channel steel yog ib tug ntev sawb ntawm cov hlau nrog groove seem. Nws specification yog qhia nyob rau hauv millimeters ntawm duav qhov siab (H) * ceg dav (b) * duav thickness (d). Piv txwv li, 120 * 53 * 5 sawv cev rau channel steel nrog lub duav siab ntawm 120 hli, ceg dav ntawm 53 hli, thiab lub duav tuab ntawm 5 hli, lossis 12 # channel steel. Rau channel steel nrog tib lub duav qhov siab, yog tias muaj ob peb ceg dav dav thiab lub duav thicknesses, a, B thiab C yuav tsum tau ntxiv rau sab xis ntawm tus qauv, xws li 25A #, 25B #, 25C #, thiab lwm yam.
Nws tau muab faib ua tib yam channel steel thiab lub teeb channel steel. Qhov tshwj xeeb ntawm kub dov zoo tib yam channel steel yog 5-40 #. Qhov tshwj xeeb ntawm kub dov hloov tau yooj yim channel steel muab los ntawm kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom yog 6.5-30 #. Channel steel yog tsuas yog siv nyob rau hauv lub tsev qauv, tsheb tsim thiab lwm yam kev lag luam qauv. Channel steel feem ntau siv nrog I-beam.
Tsis yog tus qauv channel steel yog raws li lub duav qhov siab, ceg dav, duav thickness thiab qhov hnyav ib meter ntawm channel steel. Nws yog tsuas yog kom txuag tau tus nqi yam tsis muaj kev cuam tshuam rau kev nyab xeeb thiab zoo, thiab luv nqi ntawm qhov siab, dav thiab thickness. Piv txwv li, qhov hnyav ntawm 10a # channel steel yog 10.007kg ib meter thiab 60.042kg rau 6m. Yog tias 6m tsis yog tus qauv 10a # channel steel yog 40kg, peb hu nws qhov sib txawv qis ntawm 33.3% (1-40 / 60.042).
