Nyuma y'ibiganiro byinshi ku bisobanuro bya tekiniki no gusuzuma ibishushanyo mbonera by'imiterere, ndetse n'isesengura ry'imizigo y'isi, CHINA ROYAL STEEL yatanze igisubizo cyuzuye ikoresheje imiraba ya H, ibyuma by'inguni n'ibice by'icyuma - byose bikozwe mu buryo bujyanye n'imiterere ikenewe y'inyubako ya leta. Ibyiza by'ingenzi ni ibi bikurikira:
Imiringoti ya H (Urufunguzo rw'ibanze rutwara imizigo): Inkingi n'umurambararo by'urukuta rw'inyubako byakozwe muri Q355B (igereranywa na ASTM A36) H-beams zo mu rwego rwa H, ari na zo zubakwa mu cyuma gishyushye cya H-beam. Izi zubakwa zifite imbaraga mu kwihanganira imitwaro no kurwanya imitingito, zifite imbaraga nkeya za 355 MPa n'imbaraga nkeya za 470 MPa. Kugira ngo habeho urwego rw'ubutaka n'ibice bitandukanye by'inyubako, hakoreshejwe ingano zihariye (uburebure: 200–600 mm, ubugari bwa flange: 100–250 mm, ubugari bwa web: 6–14 mm).
Ibyuma by'inguni (Gufata no gushushanya imiterere y'inyubako): Ibyuma bya Q235B (bingana na ASTM A283 Gr.C) byakoreshejwe mu gushyiramo imigozi, guhuza ibisenge no gushyiramo inkuta. Uburyo bworoshye bwo kugenda no guhindagurika kw'ibi byuma bigira uruhare mu gutuma imiterere ihamye no kudakomera ku mihindagurikire y'isi. Ingano zabigenewe (uburebure bw'amaguru: mm 50–125, ubunini: mm 5–10) zahujwe n'ibikenewe mu mikoranire mu bwubatsi budatwara imizigo no mu nyubako aho bikenewe ko habaho ituze rinini.
Icyuma (Izibambo zo hasi, Gukomeza inyubako): Amasahani y'icyuma ya ASTM A36 yakoreshejwe ku masahani yo hasi n'ahantu hakomeye ho gukomeza imiterere. Amasahani akora ubusudizi bworoshye hamwe n'imirasire ya H n'uburyo bwo kohereza imizigo buhamye mu gihe cy'ubugari bungana (8 ~ 20mm) kandi burambuye kandi bucunga neza ubuziranenge bw'ubuso.
Iyubahirizwa ry'Ubuziranenge: Imiterere y'imiti, imiterere ya mekanike n'ubuziranenge bw'imiterere y'ibyuma byose bipimwa neza. Bigomba gukorerwa isuzuma ryuzuye hakurikijwe amahame mpuzamahanga ya ASTM, El Salvador yo mu gace, amategeko y'inyubako yo mu gace, n'ibyemezo byuzuye by'ubuziranenge biratangwa kugira ngo ushyikirizwe leta kugira ngo umushinga wemerwe.
