H-matanda muChina anonyanya kugadzirwa uye akaiswa muzvikamu zvichienderana neHot Rolled H-matanda uye Sectional T-matanda (GB/T 11263-2017). Zvichienderana nehupamhi hweflange, inogona kuiswa muhupamhi-flange H-beam (HW), yepakati-flange H-beam (HM) uye nhete-flange H-beam (HN). Semuenzaniso, HW100×100 inomiririra yakafara flange H-beam ine flange yakafara 100mm uye kureba kwe100mm; HM200×150 inomiririra yepakati flange H-beam ine flange yakafara 200mm uye kureba kwe150mm. Mukuwedzera, kune inotonhora-yakaumbwa simbi yakatetepa uye mamwe marudzi anokosha eH-matanda.

European Standards (EN)

H-matanda muEurope anotevera nhevedzano yezviyero zveEuropean, senge EN 10034 uye EN 10025, iyo inotsanangura iyo dimensional yakatarwa, zvinhu zvinodiwa, michina zvivakwa, pamusoro pemhando uye mitemo yekuongorora yeH-matanda. Common European standard H-matanda anosanganisira HEA, HEB uye HEM akatevedzana; iyo HEA yakatevedzana inowanzo shandiswa kumirisana neaxial uye vertical masimba, senge muzvivakwa zvepamusoro-soro; iyo HEB yakatevedzana inokodzera zvidiki kusvika pakati-kati masisitimu; uye HEM yakatevedzana inokodzera zvikumbiro zvinoda kureruka uremu dhizaini nekuda kwehurefu hwayo uye huremu.
