Aluminium profile saw hniav yog tshwj xeeb txiav cov hniav rau cov ntaub ntawv aluminium alloy. Aluminium yog ib qho nyuaj dua li ntoo, tab sis ntoo kuj muaj cov yam ntxwv tshwj xeeb, uas yog, nws muaj ntau cov ntoo fibers thiab muaj zog toughness, yog li nws yog ib qho tsim nyog los txiav ob hom khoom sib txawv, zoo heev. txawv. Aluminium profile pom hniav yog hom hniav trapezoidal tiaj tus hniav, lub kaum sab xis yog 6-10 degrees, thiab lub kaum sab xis ntawm cov hniav yog 0 degrees; rau kev txiav cov ntaub ntawv txhuas, xws li cov hniav zoo nkauj thiab lub kaum sab xis tsim yog heev nyob rau hauv txoj kab nrog cov yam ntxwv ntawm txhuas raws li cov khoom siv; thiab saw hniav rau txiav ntoo feem ntau yog sab laug thiab sab xis, nrog lub kaum sab xis pem hauv ntej ntawm ntau tshaj 15 degrees, ib tug hniav inclination lub kaum sab xis ntawm 5-10 degrees, thiab kuj loj rear kaum sab xis thiab lub ntsiab deflection kaum sab xis. Tsuas yog cov qauv tsim no tuaj yeem ua kom ntseeg tau tias cov saw hniav muaj qhov ntse txaus thaum nws los txog rau fibers.
