1. Tsananguro yeStandard neGrade

EN10219: Mutemo uyu unotsanangura mamiriro ekugadzirwa kwehunyanzvi hwezvikamu zvedenderedzwa, sikweya, kana rectangular zvakagadzirwa nesimbi isina alloy uye simbi yekuvaka. Inosanganisira kuumbwa kwemakemikari, hunhu hwemakanika, kushivirira kwehukuru, uye zvinodiwa zvekuedza zvisingaparadze.

S355J2H:

S: Simbi Yekuvaka

355: Simba shoma remubereko we355 MPa (yeukobvu hwemadziro≤16mm)

J2: Charpy V-notch simba remhedzisiro≥27J pa -20°C

H: Chikamu chine Homwe

2. Hunhu Hunokosha hweMichina uye Maitiro

Kukosha Kwepfuma Kwakajairika / Kukosha Kwezvinodiwa zveMapurojekiti eEurope

Simba reKubereka (ReH)≥355 N/mm²Inoderedza kuzviremera uye kushandiswa kwesimbi yese

Simba reKusimba (Rm) 470–630 N/mm²Inopa mukana wekuchengetedza wakavimbika

Kureba mushure mekutyoka≥20% Inovimbisa kuti zvinokwanisika kukotama nekuumbwa kwechando

Kugona kusundira CEV≤0.40 (yakajairika) Inoenderana nemaitiro akajairika ekuwelda, kupisa kushoma

3. Mashandisirwo Akajairika (Mienzaniso yeMusika weEurope)

Kuvaka & Zvivakwa: Zvigadziko zvenhandare, madenga echiteshi, zvitsigiro zveshongwe, zvivakwa zvenguva pfupi zvekudzivirira.

Michina & Zvishandiso: Crane booms, zvinotsigira conveyor, zvikamu zvemuchina wekurima.

Mabhiriji & Zvivako zveMigwagwa: Zvigadziko zvemabhiriji evanofamba netsoka, masisitimu ekudzivirira, zvivakwa zvemakusheni ekuputika.

Uinjiniya hweSimba neNzvimbo: Zvitsigiro zvemukati zvemashongwe emhepo, mafuremu ekuisa PV, zvivakwa zvepuratifomu yekurapa mvura yakasviba.

4. Zvinhu Zvikuru Zvekufunga Nezvazvo Pakupinda Mumusika weEurope

Chitupa cheEN 10204: Chitupa chekuongorora chemhando ye3.1 kana 3.2 chinowanzo dikanwa kuratidza kutevedzera mwero.

Kudzora Pamusoro & Pachipimo: Tevedzerai zvakadzama zvinodiwa pakushivirira zviri mu EN10219-2; pamusoro panofanira kunge pasina mitswe, mapasuru, kana zvimwe zvikanganiso.

Kutevedzana: Chikamu chimwe nechimwe chine mhango chinofanira kunge chakaiswa giredhi resimbi, nhamba yekupisa, uye nhamba yakajairwa kuti chive nechokwadi chekuti chinonyatsotevedzana.

DoP (Kuzivisa Kushanda): Kana chigadzirwa chine chiratidzo cheCE, Chiziviso Chekushanda chinofanira kupihwa zvichienderana neConstruction Products Regulation (CPR).

EN10219 S355J2H, ine simba rayo rakaringana, kusimba kwayo kwakanyanya pakupisa kwakaderera, uye kushanda kwayo zvakanaka, inoenderana zvakakwana nemusika weEurope.'Zvinodiwa zvesimbi yekuvaka yakachengeteka, yakavimbika, uye inoshanda zvakanaka. Kune vatengesi vari kuda kupinda kana kuwedzera muEurope, kupa magwaro akazara emhando yepamusoro, kudzora zvakanyanya kushivirira, uye kuve nechokwadi chekuti zvinhu zvinoteverwa ndizvo zvakakosha pakushandisa chigadzirwa ichi zvinobudirira mumapurojekiti eEurope.
