Technical Specifications
Product Overview
Metallurgical Characteristics
Rebar Steel features a predominantly ferritic-pearlitic microstructure optimized for structural reinforcement applications. The controlled carbon content and manganese addition provide excellent strength-to-weight ratio while maintaining superior ductility. The deformed surface pattern with transverse ribs ensures optimal mechanical bond with concrete, critical for load transfer in reinforced concrete structures.
Heat Treatment Process
MetalZenith employs controlled hot rolling at temperatures between 1050-1150°C followed by controlled cooling to achieve optimal mechanical properties. The thermomechanical processing includes precise temperature control during rolling and controlled cooling rates to develop the required yield strength while maintaining excellent ductility and weldability characteristics.
Manufacturing Process
Our state-of-the-art production facility utilizes continuous casting followed by hot rolling mills with advanced rib rolling technology. The process includes real-time dimensional control, automated surface inspection, and precision cutting systems. Quality control checkpoints ensure consistent rib geometry, straightness tolerance, and mechanical properties throughout production.
Structural Quality Testing
MetalZenith conducts comprehensive testing specific to structural applications including: weldability assessment per AWS D1.4 standards, bend testing for ductility verification, fatigue strength evaluation under cyclic loading conditions, and atmospheric corrosion resistance testing. Additional tests include bond strength evaluation and seismic performance validation for earthquake-resistant construction.
Application Engineering
For building construction applications, our rebar provides exceptional load-bearing capacity and seismic resistance. In bridge engineering, the superior fatigue strength ensures long-term durability under dynamic loading. For mechanical manufacturing and vehicle construction, the excellent weldability and formability enable complex structural assemblies. General engineering applications benefit from the consistent quality and reliable performance in diverse environmental conditions.
