Cov hlau hlau tau muab faib ua cov hlau hlau thiab hlau hlau hlau. Nws lub luag haujlwm yog qhov dav heev. Xws li lub caij nplooj ntoo hlav, steel hlau hlua, vuam hlau thiab lwm yam. Nws lub zog tensile yog los ntawm kaum tawm kilograms mus rau ntau dua ib puas kilograms.
Cov hlau hlau nyuaj dua, muaj lub zog siab thiab zoo elasticity;
Qhov saum npoo ntawm cov hlau hlau feem ntau raug kho los qhia dub txhob lo lo ntxhuav,
Hlau hlau feem ntau tsis galvanized. Nws yog ua los ntawm cov txheej txheem carbon hlau. Nws yog siv rau cov tshuab thiab cov dej ntws. Dub, tawv heev;
Cov pa roj carbon cov ntsiab lus tsawg dua lossis sib npaug li 2.11%. Qhov thib ob, cov ntsiab lus ntawm cov khoom tsis huv sib txawv, thiab cov ntsiab lus ntawm cov khoom tsis zoo xws li leej faj thiab phosphorus hauv hlau yog me dua.
Cov ntsiab lus: Cov xim dav dav ntawm cov hlau hlau yog qhov zoo, thiab lub zog ntawm cov hlau hlau yog siab los ntawm qhov pom ntawm cov khoom siv engineering.
