Izinamathiselo zesakhiwo ziphezulu-izinamatheliso ezinamandla (amandla acindezelayo > 65 MPa, insimbi-kuya{3}}kuya{3}}amandla ebhondi eqinile yensimbi > 30 MPa, amandla okugunda > 18 MPa), ekwazi ukumelana nemithwalo esindayo, futhi imelana nokuguga, ukukhathala, nokugqwala. Abonisa ukusebenza okuzinzile kuyo yonke impilo yawo elindelekile futhi afanelekela izingxenye zesakhiwo eziboshiwe ezingaphansi kwamandla aphezulu.
Okunamatheliswayo okungewona-esakhiweni anamandla aphansi kanye nokuqina okubuthakathaka, futhi angasetshenziswa kuphela ekuhlanganiseni okuvamile, kwesikhashana, ukuvala, nokulungisa; azikwazi ukusetshenziselwa ukuhlanganisa izingxenye zesakhiwo.
Izinamatheliso zesakhiwo ziphezulu-zinamandla, ziyaxebuka-azizweli, azithinteki{2}}ziyamelana, futhi kulula ukuzisebenzisa. Zisetshenziselwa ukuhlanganisa izinto ezifanayo noma ezingafani njengezinsimbi, izitsha zobumba, ipulasitiki, irabha, nokhuni. Zingashintsha ngokwengxenye izindlela zokuxhuma zendabuko ezifana nokushisela, i-riveting, kanye ne-bolting. Ukusatshalaliswa kwengcindezi endaweni yokubopha kufana, akukho zindawo zokushisa-ezithintekile noma ukuwohloka kwezingxenye.
Izinamathiselo zesakhiwo zisetshenziswa kakhulu kwezobunjiniyela, ikakhulukazi ukuqinisa, ukubopha, ukubopha, nokulungisa izingxenye; njengensimbi ebophayo, i-carbon fiber ebophayo, ukufakwa kabusha kwe-rebar, ukuqinisa ukuqhekeka nokuvala, ukulungisa imigodi, ukubopha izipikili zomgwaqo, ukuvikelwa kwendawo, kanye nokubopha ukhonkolo.
