Technical Specifications
Product Overview
Steel Rebar (Reinforcing Bar) is manufactured from high-quality carbon steel designed specifically for concrete reinforcement applications. This deformed steel bar provides excellent bond strength with concrete and meets stringent construction industry standards for structural integrity.
Key Features:
- Superior bond strength with concrete due to deformed surface
- High tensile and yield strength for structural applications
- Excellent ductility and bendability
- Corrosion resistant coating options available
- Consistent mechanical properties throughout length
Manufacturing Process: Hot-rolled from quality billets using controlled rolling technology, followed by precision cutting and surface deformation to create optimal rib patterns for concrete bonding.
Applications: Reinforced concrete construction, building foundations, bridges, highways, tunnels, retaining walls, precast concrete elements, and general structural concrete reinforcement in residential and commercial projects.
