Déantar boltaí ancaire a mhonarú as cruach carbóin, cruach cóimhiotail, nó cruach dhosmálta, le gráid ábhar coitianta lena n-áirítear Q235, Q345, agus gráid ainmnithe ASTM
Tá na boltaí ar fáil i dtrí ghrád neart (neart toraidh 36, 55, agus 105 ksi) mar atá sonraithe faoi ASTM F1554, a chlúdaíonn cumraíochtaí díreach, lúbtha, ceann, agus gan cheann. Is féidir toisí a shaincheapadh go hiomlán thar raon leathan, le trastomhais tipiciúil ó M6 go M100 agus faid in oiriúint do riachtanais shonracha doimhneacht leabaithe.
Rialaíonn roinnt caighdeáin idirnáisiúnta sonraíochtaí boltaí ancaire, lena n-áirítear ASTM F1554 le haghaidh boltaí ancaire cruach, ASTM A307 agus A449 le haghaidh feidhmeanna ginearálta, chomh maith le caighdeáin DIN, GB, ISO, agus ANSI. I measc na bailchríocha dromchla atá ar fáil tá plain (neamhbhrataithe), plating since, galbhánú te-tumtha, ocsaíd dhubh, agus sciath eapocsa. I measc na n-iarratas coitianta tá colúin tógála, comharthaí mórbhealaigh, soilsiú sráide, comharthaí tráchta, tacaí droichead, fondúireachtaí innealra, agus trealamh tionsclaíoch a dhaingniú.
