FIELD: process engineering.
SUBSTANCE: invention relates to construction reinforced concrete structures. To increase adhesion between reinforcements and concrete, load bearing capacity in compression, and fire resistance, rolled section reinforcements are rolled from tubular billets of alloyed steel "25Г2С", "30ХГ2С", "35ГС" intended for reinforced concrete structures, and reef-like ledges are rolled on their surface. Note here that said ledges are rolled in hot state by transverses rolling along left of right mono- or multifilar helix.
EFFECT: higher adhesion.
