Product Name: Thermo-Mechanically Treated High Strength Rebar

Overview

TMT Bar is a ribbed steel bar produced through an advanced "Thermo-Mechanical Treatment" process. This process involves stages of quenching and self-tempering, resulting in a hard martensitic surface and a soft, ductile ferrite-pearlite core. This unique "hard-soft" microstructure provides a superior combination of high yield strength, excellent ductility, and high fatigue resistance, making it an ideal material for modern seismic-resistant construction.

Technical Specifications

Key Advantages

Superior Seismic Performance

High Yield/Tensile Ratio: Ensures significant plastic deformation after yielding, preventing brittle collapse during earthquakes and providing crucial time for evacuation.

High Elongation: Absorbs more energy, effectively resisting dynamic loads like earthquakes.

Higher Strength & Durability

High strength allows for design optimization, saving steel and reducing overall project cost.

Excellent corrosion resistance and fatigue strength enhance the service life of the structure.

Excellent Weldability & Bendability

Controlled carbon equivalent allows for easy on-site welding without complex pre-heating.

The ductile core allows for easy cold bending to meet various construction needs.

Cost-Effectiveness

It can save up to 10%-15% in steel consumption compared to ordinary grades while achieving the same structural performance.

Typical Applications

High-Rise & Skyscrapers: Core reinforcement in columns, beams, and shear walls.

Infrastructure: Bridges, dams, tunnels, ports, power stations.

Industrial Structures: Heavy-duty factory buildings, warehouses.

Residential & Commercial Buildings: Foundations, slabs, columns, beams.
