Emva kwengxoxo ezininzi ngeenkcukacha zobugcisa kunye nokuphononongwa kwemizobo yoyilo lwesakhiwo, kunye nohlalutyo lwemithwalo yenyikima, iCHINA ROYAL STEEL inikeze isisombululo esipheleleyo sisebenzisa ii-H-beams, ii-angle steels kunye neepleyiti zentsimbi - zonke zenziwe ngokweemfuno zesakhiwo sikarhulumente. Iingenelo eziphambili zezi:
Ii-H-Beams (Isakhelo esiPhambili sokuThatha uMthwalo): Ikholamu kunye nomqadi wesakhelo sesakhiwo zenziwe ngee-H-beams ze-Q355B (ezithelekiswa ne-ASTM A36), oluluhlobo lwe-H-beam yentsimbi efudumeleyo egoqwe kakuhle. Ezi ntsimbi ze-H ziqinile ekuthwaleni umthwalo kunye nokumelana nenyikima ngamandla amancinci okuvelisa angama-355 MPa kunye namandla amancinci okutsalwa angama-470 MPa. Ukwanelisa amanqanaba ahlukeneyo omgangatho kunye namacandelo esakhiwo, kusetyenziswe imilinganiselo eyenzelwe wena (ukuphakama: 200–600 mm, ububanzi beflange: 100–250 mm, ubukhulu bewebhu: 6–14 mm).
Iintsimbi ze-Angle (Ukuxhasa kunye nokuGqiba ulwakhiwo)Iintsimbi ze-engile ze-Q235B (ezilingana ne-ASTM A283 Gr.C) zisetyenziselwe ukubethelela, uqhagamshelo lwe-truss yophahla kunye nolwakhiwo lodonga. Ukuqina okugqwesileyo kunye nokugoba kwezi ntsimbi kuncedisa kwisakhiwo esizinzileyo ngakumbi kunye nokumelana nokushukuma komhlaba. Ubukhulu obulungiselelwe wena (ubude bemilenze: 50–125 mm, ubukhulu: 5–10 mm) buhlengahlengiswe kwiimfuno zoqhagamshelo ezinzima kwizakhiwo ezingezizo ezomthwalo kunye nezicelo zokwakha apho kufuneka uzinzo olukhulu.
Iphepha Lentsimbi (IiSlabs Zomgangatho, Ukuqinisa Ulwakhiwo): Iipleyiti zentsimbi ze-ASTM A36 zasetyenziswa kwiislab zomgangatho kunye neendawo eziqiniswe kakhulu. Iipleyiti zenza ukuwelda okugudileyo ngemiqadi ye-H kunye nokudluliselwa komthwalo ozinzileyo phantsi kobukhulu obulinganayo (8 ~ 20mm) kunye nokuthe tyaba okuphezulu kunye noLawulo oluqinileyo loMgangatho woMphezulu.
Ukuthobela Umgangatho: Ukwakheka kweekhemikhali, iimpawu zoomatshini kunye nokuchaneka kobukhulu bazo zonke iiprofayili zentsimbi kuvavanywa ngokungqongqo. Ziyakhalazelwa ngokupheleleyo yimigangatho ye-ASTM International, i-El Salvador yasekuhlaleni, iikhowudi zeZakhiwo zasekuhlaleni, kunye neeSatifikethi zoMgangatho ezipheleleyo ziyanikezelwa ukuze zingeniswe kurhulumente ukuze zamkelwe yiprojekthi.
