Munyika yemazuva ano yeinjiniya yekuvaka nekuvaka, sarudzo yesimbi haisi yekufungidzira. Maviri emaplate esimbi anonyanya kutaurwa anopisa anoputirwa—ASTM A572 Giredhi 50uyeASTM A992—vakazvisimbisa sezvinodiwa neindasitiri yemapurojekiti anoda kuenzana kwesimba, ductility, uye kuvimbika.
Plate yesimbi inopisa yeASTM A572 Giredhi 50iplate yesimbi yakasimba kwazvo, isina alloy yakawanda inoshandiswa zvakanyanya mukushandiswa kwezvivakwa, mabhiriji, uye kugadzirwa kwakajairika. Simba rayo rinopa simba re50 ksi (345 MPa) uye simba rekudhonza rinotangira pa65–80 ksi (450–550 MPa)ita kuti ive sarudzo inoshandisika kune mainjiniya vanoda kushanda zvakanaka uye kushandisa mari zvakanaka. Pamusoro pezvo, ASTM A572 Giredhi 50 inoratidza kugona kuchinjika uye kugadzirwa zvakanaka, zvichibvumira kugadzirwa kwakaoma pasina kukanganisa kunaka kwesimbi. Kubatanidzwa kwesimba, kuomarara, uye kuramba ngura kunoita kuti ive yakakodzera zvivakwa zvinorema, kusanganisira zvivakwa zvemaindasitiri, mapuratifomu emuchina, uye zvivakwa zvekufambisa.
Pane rimwe divi,Plate yesimbi inopisa yeASTM A992rave chinhu chinodiwa pakugadzira maumbirwo emadziro ane flange yakakura, kunyanya kuNorth America. Pakutanga yakagadzirwa kuti itsive ASTM A36 muzvimiro zvemaumbirwo, A992 inopa simba rekugadzira re50 ksi (345 MPa), pamwe nekusimba kwakanyanya uye ductility, zvichiita kuti ive yakakodzera kune zvivakwa zvisingapindike nekudengenyeka kwenyika. Simbi yeA992 inewo kugona kupeta nekunamira zviri nani, izvo zvinobvumira vagadziri vemaumbirwo kusangana nezvinodiwa zvemagadzirirwo akasimba zvinobudirira. Kushandiswa kwayo kwakapararira muzvivakwa zvemabhizinesi, mabhiriji, uye mafemu emaindasitiri humbowo hwekushanda kwayo kwepamusoro mumamiriro ekutakura asingachinji uye anochinja-chinja.
Kunyange hazvo mhando dzese dzesimbi dzichishandisa simba rakafanana rekugadzira, hadzichinjiki mukushandiswa kwese. ASTM A572 Giredhi 50 inowanzo sarudzwa pakushandiswa kwemaplate anoda kuchekwa, kugadzirwa, kana kusagadzirwa zvakanyanya, nepo ASTM A992 yakagadzirirwa maumbirwo echimiro akadai seI-matandauyeH-matanda, uko kugadzikana kwakanyanya kwemativi uye kugona kuchinjika pasi pemutoro kwakakosha. Kusarudza simbi yakakodzera kunosanganisira kunyatsofunga nezvezvinodiwa nemutoro wepurojekiti, nzira dzekugadzira, uye mamiriro ezvakatipoteredza.
Kunze kwehunhu hwavo hwemakanika, zvese zviri zviviriMaplate esimbi eASTM A572 eGiredhi 50uyeMaplate esimbi eASTM A992Zvinogadzirwa kuburikidza nemaitiro epamusoro ekuputira zvinopisa. Kuputira zvinopisa kunoita kuti pave nehukobvu hwakafanana uye kupedzisa pamusoro pazvo kwakatsetseka ukuwo zvichivandudza chimiro chemukati chesimbi. Zvivako zvemazuva ano zvekugadzira zvinoshandisa zvigayo zvinotenderedzwa nekombiyuta kuti zvive nechokwadi chekuti mativi acho anowirirana, zvichiita kuti maplate aya aenderane nemapurojekiti ekuvaka nemainjiniya akanyatsojeka.
Kubva pamaonero anoshanda, mainjiniya, vagadziri vemapurojekiti, uye maneja emapurojekiti vanowanzo funga nezvekuvimbika kwecheni yekugovera uye kuwanikwa kwayo pavanenge vachitsanangura mamakisi esimbi.
