Structural steel ndi gulu lachitsulo lomwe limagwiritsidwa ntchito ngati chomangira popanga mawonekedwe achitsulo.A structural zitsulo mawonekedwe ndi mbiri, wopangidwa ndi chigawo china cha mtanda ndi kutsatira mfundo zina za mankhwala zikuchokera ndi katundu makina.Mawonekedwe azitsulo zamapangidwe, kukula kwake, kapangidwe kake, mphamvu, machitidwe osungira, ndi zina zambiri, zimayendetsedwa ndi miyezo m'maiko ambiri otukuka.

Mamembala azitsulo zazitsulo, monga I-beams, ali ndi mphindi zapamwamba zachiwiri za malo, zomwe zimawalola kukhala owuma kwambiri pokhudzana ndi gawo lawo.

Mawonekedwe odziwika bwino

Mawonekedwe omwe alipo amafotokozedwa m'miyezo yambiri yosindikizidwa padziko lonse lapansi, ndipo magawo angapo aukadaulo ndi eni ake amapezekanso.

·I-beam (gawo lofanana ndi I - ku Britain izi zikuphatikizapo Universal Beams (UB) ndi Universal Columns (UC); ku Ulaya zimaphatikizapo IPE, HE, HL, HD ndi zigawo zina; ku US pali Wide Flange (WF kapena W-Shape) ndi magawo H)

·Z-Shape (theka la flange mbali zosiyana)

·HSS-Shape (Hollow structural gawo lomwe limadziwikanso kuti SHS (structural hollow section) kuphatikizapo masikweya, amakona anayi, ozungulira (chitoliro) ndi elliptical cross section)

·ngodya (gawo lopingasa ngati L)

·Structural channel, kapena C-beam, kapena C cross-section

·Tee (gawo lopingasa looneka ngati T)

·Mbiri ya njanji (asymmetrical I-beam)

·Sitima yapanjanji

·Vignoles njanji

·Flanged T njanji

·Sitima yapamtunda

·Bar, chidutswa chachitsulo, amakona anayi mtanda gawo (lathyathyathya) ndi yaitali, koma osati lonse kotero kuti amatchedwa pepala.

·Ndodo, chitsulo chozungulira kapena lalikulu komanso chachitali, onaninso rebar ndi dowel.

·Mbale, zitsulo mapepala thicker kuposa 6 mm kapena 1⁄4 mu.

·Tsegulani cholumikizira chachitsulo

Ngakhale kuti magawo ambiri amapangidwa ndi kugudubuzika kotentha kapena kozizira, ena amapangidwa mwa kuwotcherera pamodzi mbale zafulati kapena zopindika (mwachitsanzo, zigawo zazikulu kwambiri zozungulira zamphako zimapangidwa kuchokera ku mbale yafulati yopindika kukhala yozungulira ndi yokhotakhota).
