Is cruach struchtúrach cóimhiotail ASTM A572 Grád 50 H ard-neart íseal atá deartha le haghaidh feidhmeanna tógála agus tionsclaíochta tromshaothair. Le neart táirgeachta de 345 MPa agus airíonna teanntachta den scoth, cuireann sé cumas iompair ualaigh níos fearr ar fáil agus an meáchan struchtúrach á laghdú.
Soláthraíonn a cruth rannáin H optamaithe cóimheas éifeachtach idir neart agus meáchain, infheictheacht den scoth, agus déine, rud a fhágann go bhfuil sé oiriúnach d'fhoirgnimh arda, droichid, gléasraí móra tionsclaíochta agus bunanna innealra trom.
Ar fáil i faid chaighdeánacha agus i méideanna inoiriúnaithe, is féidir an léas seo marthanach agus éifeachtach ó thaobh costais a ghalbhánú nó a phéinteáil le haghaidh friotaíocht feabhsaithe creimeadh, rud a chinntíonn feidhmíocht fhadtéarmach i dtimpeallachtaí éilitheacha.
