12 mm diameter rebar is one of the most common and extensively used steel materials, as reinforcement for structural concrete. The steel cross-section is often measured in cm2 or m2, being the direct conversion of one measurement into the other.
They offer great properties for constructions, as they are used to build concrete columns or posts, reinforcing bars, beams, concrete pipes, enclosures, chains, tie beams, tie columns, vaults, joists, prefabricated elements, masonry pieces, and construction reinforcements. They are also used as concrete reinforcement, as they avoid the longitudinal movement relative to concrete.
