Sib npaug ntse lub kaum steel muaj ntau qhov tseem ceeb. Firstly, nws cov khaub lig symmetrical -} ntu muaj lub zog sib luag hauv ob txoj kev sib tshuam. Qhov no txawv geometry ua rau nws tawm tsam kev tawm tsam ob qho tib si kev sib tw hauv ntau yam kev sib tw, txhim kho nws cov versatility hauv cov ntawv thov txheej txheem. Piv txwv li, hauv ib qho qauv truss, sib npaug ntawm lub steel cireel tuaj yeem yooj yim cuam tshuam nrog hloov cov tswv cuab sib txawv.
Qhov thib ob, sib npaug kaum steel yog tus nqi heev -}}}} Siv tau zoo. Piv rau qee qhov nyuaj {2} Daim qauv txheej txheem steel, nws yuav tsum tau cov nqi tsawg dua, ua rau muaj nqi qis dua. Qhov no pheej yig ua rau nws xaiv tau ntau ntawm cov haujlwm, los ntawm kev siv me me, los ntawm cov chaw nyob uas muaj cov nqi uas tus nqi tswj tau yog qhov tseem ceeb.
Lwm qhov zoo dua yog nws cov kev ua kom zoo thiab weldability. Sib npaug sib luag steel tuaj yeem txiav tau yooj yim, khoov, thiab puab los ua raws li cov qauv tsim tshwj xeeb. Nws cov tshuaj lom neeg tso cai rau kev txhim khu kev siv vuam, ua kom cov ntaub npuag txhim kho kom koom nrog ntau cov ntu ua ke los tsim cov qauv customized. Seb nws yog rau tsim cov khib nyiab hlau yooj yim lossis lub hom phiaj ua haujlwm thiab weldability ntawm sib npaug ntawm cov txheej txheem fab raug thiab cov nqi tsim kho.
