Steel Rebar
Deformed Rebar
Unique Features of Deformed Rebar
- Textured Surface for Enhanced Bonding: The ribs or deformations on the surface of the rebar significantly increase the bond with concrete. This ensures that the rebar stays securely embedded, providing improved structural integrity in reinforced concrete.
- High Tensile Strength: Deformed rebar comes in various grades, with Grade 60 (60,000 psi) and Grade 75 (75,000 psi) being particularly popular. These grades offer superior tensile strength, making them ideal for high-load-bearing applications.
- Corrosion Resistance: Many types of deformed rebar are manufactured with enhanced corrosion resistance to extend the service life of concrete structures exposed to harsh environments such as marine or industrial zones.
- Versatility in Applications: Available in a variety of sizes, lengths, and grades, deformed rebar can be used for a wide range of applications, from residential buildings to massive infrastructure projects such as bridges and highways.
