Inguni za ASTM, izwi kandi nka angle steel, igira uruhare runini mu gutanga inkunga y’inyubako no guhagarara neza ku bintu bitandukanye kuva ku minara y’itumanaho n’iy’amashanyarazi kugeza ku mazu yo gukoreramo n’inyubako z’ibyuma, kandi ubuhanga bwo gukora neza inyuma y’agace k’inguni gapima uburebure bw’igipimo cy’inguni butuma zishobora kwihanganira imitwaro iremereye.
Akabati k'icyuma ka ASTMziboneka mu bwoko bubiri, zingana n'izingana, bitewe n'ubujyakuzimu bw'amaguru. Inguni zitangana, zizwi kandi nka L-shaped steel, zikoreshwa iyo ukuguru kumwe kw'inguni ari kure kurusha ukundi, mu gihe inguni zingana zikoreshwa iyo amaguru yombi angana mu burebure, bigatuma inguni za ASTM zikwiriye gukoreshwa mu buryo butandukanye.
Uretse ikoreshwa ry'inganda n'ubwubatsi,Agakoresho k'inguni gakozwe mu bisefa (ASTM galvanized arc)bishobora kuboneka mu bintu bya buri munsi. Kuva ku nganda zitunganya amabati kugeza ku meza asanzwe ya kawa, ibi bigaragaza uburyo impande za ASTM zihuzwa n’uburyo zikoreshwa mu buryo bwagutse mu mibereho yacu yose.
Imiterere ya ASTM yemeza ko inguni zujuje amahame agenga ibizamini n’ibikoresho by’Abanyamerika, bivuze ko zikorwa kandi zikageragezwa hakurikijwe imiterere yihariye ya mekanike, harimo imbaraga zo gukuraho, imbaraga zo gukurura, no kurekura.
Ubuhanga mu by'ubuhanga buri inyumainguni ya ASTMbihamya ko ubushobozi bwo gukora ibyuma bifite ingano zihamye n'imiterere ya mekanike ari ingenzi kugira ngo inyubako, iminara n'indi mishinga y'ubuhanga bibe neza. Ubu buhanga bunoze kandi butuma ibikoresho bikoreshwa neza, bugabanya imyanda kandi bugatuma imirimo yose y'ubwubatsi irushaho kuba myiza.
