Ulwakhiwo lweNsimbi ye-ASTM A913 | Intsimbi ye-H-Beam enamandla aphezulu yezakhiwo zemizi-mveliso nezorhwebo
Ulwakhiwo lweSakhelo seTruss yeNsimbi seSakhiwo seModular Isakhelo setruss yentsimbi luhlobo lwenkqubo yolwakhiwo apho amalungu entsimbi adityaniswe khona ngendlela yeeyunithi ezinxantathu ngokulandelelana okuthile ukwenza isakhelo esiqinileyo esinokusetyenziselwa ukuxhasa imithwalo esetyenzisiweyo. Imilo enxantathu ikhulisa amandla kunye nozinzo ngezinto ezincinci kwaye ifanelekile ixesha elide kunye negumbi elivulekileyo.
Iimpawu ezibalaseleyo
Umlinganiselo Ophezulu Wokuqina-ukuya-Kubunzima -- Ijiyometri yetruss enxantathu ivumela amandla okuthwala umthwalo aqinileyo ngentsimbi encinci.
I-Wide Clear Span - Igubungela indawo ebanzi engenazo iikholamu zangaphakathi.
Uyilo oluneenjongo ezininzi - Lulungele iindawo zokugcina impahla, iiworkshop, izityalo zokuvelisa kunye neeholo kunye neeholo zemidlalo.
Ukwenziwa kwangaphambili kunye nokuhlanganiswa ngokukhawuleza - Iinxalenye zentsimbi zinqunyulwa kwangaphambili kwaye zenziwe ngaphandle kwendawo kwaye zibotshelelwe ngokukhawuleza kwindawo.
Ubude bexesha elide – Xa kusetyenziswa ngokufanelekileyo ukhuseleko lokugqwala (ukugalela i-galvanizing, ukupeyinta, okanye ukugquma), isakhiwo sentsimbi siya kuhlala ixesha elide kangangeminyaka emininzi.
