TOR Definition historic

The correct technical term for TOR steel (which to my knowledge is a trade mark) is Cold Twisted Deformed (CTD) Steel Reinforcement Bar. These are steel bars with surface deformations formed by twisting the steel after elongation. The elongattion process imparts higher yield strength to steel (increases from 250 to say 500MPa) and surface corrugations impart higher bondage with concrete.

TOR steel is one of the best grade of steel used in concrete reinforced. It's a kind of high adherence steel. Other types of steel are used for less resistance concrete. In french TOR steel is known as HA: haute adérance
