This is a type of deformed high strength steel. These bars are manufactured by controlled cold twisting of hot rolled bars. These bars have ribs or projection on their surface. The ribbed tor steel bars are available in different sizes varying 6mm to 50 mm in diameter. These bars are commonly used as reinforcement in concrete structures such as building, bridge, road, precast concrete etc.
Advantages of Ribbed Tor Steel Bars
Ribbed tor steel bars can be bent through 1800 without formation of any crack or fracture on their outside surface.
Welding is possible in these types of bars. It can be welded by electric flash butt welding or arc welding.
Use of these bars reduces the cost of reinforcement up to 30 to 40%, hence economical.
These bars are easily identified as they have got peculiar shape.
The structural properties of these bars are better than that of ordinary plain round bars.
These bars possess excellent bonding properties and hence the end hooks are not required.
They can be used for all major types of reinforced concrete structure.
Bending, fixing and handling of these bars are very simple. This result in to less labour charge.
