Ngemva kwengxoxo eningi ngemininingwane yobuchwepheshe kanye nokubuyekezwa kwemidwebo yokwakheka kwesakhiwo, kanye nokuhlaziywa kwemithwalo yokuzamazama komhlaba, i-CHINA ROYAL STEEL inikeze ikhambi eliphelele isebenzisa izinsimbi ze-H, izinsimbi ezigobile kanye namapuleti ensimbi - konke kwenziwe ngokwezifiso zesakhiwo sikahulumeni. Izinzuzo ezibalulekile yilezi:
Ama-H-Beams (Uhlaka Oluyinhloko Oluthwala Umthwalo): Ikholomu kanye nomshayo wohlaka lwesakhiwo kwenziwe nge-Q355B (eqhathaniswa ne-ASTM A36) grade H-beams, okuwuhlobo lwe-H-beam yensimbi egoqiwe efudumele. Le mishayo ye-H iqinile ekuthwaleni umthwalo kanye nokumelana nokuzamazama komhlaba ngamandla amancane okukhiqiza angu-355 MPa kanye namandla amancane okudonsa angu-470 MPa. Ukuze kwaneliswe amazinga ahlukene phansi kanye nezingxenye zesakhiwo, kwasetshenziswa ubukhulu obufanele (ukuphakama: 200–600 mm, ububanzi be-flange: 100–250 mm, ubukhulu bewebhu: 6–14 mm).
Izinsimbi Ze-Angle (Ukubopha Nokuhlela Isakhiwo): Izinsimbi ze-engeli ze-Q235B (ezilingana ne-ASTM A283 Gr.C) zasetshenziswa ekuhlanganiseni izinti, ukuxhumanisa i-roof truss kanye nokubiyela udonga. Ukuqina okuvelele kanye nokugoba kwalezi zinsimbi kunegalelo esakhiweni esizinzile kanye nokumelana nokuzamazama komhlaba. Ubukhulu obuqondene nomuntu ngamunye (ubude bemilenze: 50–125 mm, ubukhulu: 5–10 mm) baguqulwa ukuze bavumelane nezidingo zokuxhuma eziyinkimbinkimbi ekwakheni okungenazo imithwalo kanye nezicelo zokwakha lapho kudingeka khona ukuzinza okukhulu.
Ishidi Lensimbi (Ama-Slabs Aphansi, Ukuqinisa Isakhiwo): Amapuleti ensimbi e-ASTM A36 asetshenziswa kuma-slab phansi nasezindaweni eziqiniswe kakhulu. Amapuleti enza ukushisela okubushelelezi ngemishayo ye-H kanye nokudluliswa komthwalo okuzinzile ngaphansi kwesimo sobukhulu obulinganayo (8~20mm) kanye nokuba yisicaba okuphezulu kanye nokuphathwa kwekhwalithi ephezulu okuqinile.
Ukuthobela Ikhwalithi: Ukwakheka kwamakhemikhali, izakhiwo zemishini kanye nokunemba kobukhulu bawo wonke amaphrofayili ensimbi kuhlolwa ngokuqinile. Ziyakhononda ngokuphelele ngezindinganiso zamazwe ngamazwe ze-ASTM, i-El Salvador yendawo, amakhodi okwakha endawo, kanye nezitifiketi zekhwalithi eziphelele zinikezwa ukuze zithunyelwe kuhulumeni ukuze kwamukelwe iphrojekthi.
