A deformed steel bar, often referred to as rebar, is a steel bar with surface deformations or ridges used to reinforce concrete structures. These deformations improve the bar's bond with concrete, ensuring that it does not slip under stress, thereby providing additional strength and stability to the structure. 

Key Characteristics:
- Material: High-strength steel, typically with a carbon content that balances ductility and strength.
- Surface: The deformations on the surface, such as ridges or patterns, increase the friction between the bar and concrete.
- Sizes: Available in various diameters, commonly ranging from 6mm to *0mm, depending on the structural requirements.
- Lengths: Standard lengths are typically 6 meters or *2 meters, but they can be cut to specific sizes as needed.
- Grades: Classified by yield strength, with common grades like *0, *0, or *5, indicating the tensile strength in ksi (kilo-pound per square inch).

Applications:
- Used primarily in reinforced concrete construction, including buildings, bridges, roads, and other infrastructure projects.
- Provides tensile strength and helps control cracking in concrete structures.

Compliance:
- Manufactured according to various international standards, such as ASTM A**5, BS ***9, or other local standards depending on the region.

Overall, deformed steel bars are essential in construction for their role in improving the structural integrity and durability of concrete-based projects.
