Product Name: Hot-Dip Galvanized Thermo-Mechanically Treated Rebar

Overview

Galvanized TMT Rebar is the ultimate corrosion-resistant steel bar, which undergoes the Thermo-Mechanical Treatment (TMT) process for high strength and ductility, followed by a hot-dip galvanizing process to create a robust zinc coating. It combines the superior mechanical properties of TMT bars (high yield-to-tensile ratio, excellent seismic performance) with the unmatched corrosion resistance of a zinc coating, providing dual protection—from the core (rebar performance) and the surface (corrosion protection)—for concrete structures, especially in harsh environments for permanent works.

Key Advantages

Unmatched Corrosion Service Life

The zinc coating acts as both a physical barrier and a sacrificial anode, providing active and passive protection. It effectively resists chloride ions and carbonation, extending the structure's life by decades and significantly reducing maintenance costs.

Superior Seismic & Mechanical Properties

Retains the core "hard-soft" characteristics of TMT bars, featuring a high yield-to-tensile ratio and high elongation to absorb massive energy under extreme loads like earthquakes, preventing brittle failure.

Bond Strength with Concrete

The specially treated galvanized surface maintains a bond strength with concrete comparable to that of ungalvanized ribbed bars, ensuring effective stress transfer without compromising structural design performance.

Cost-Effectiveness & Sustainability

While the initial cost is higher, it is highly economical over the entire lifecycle due to the avoidance of frequent repairs and premature replacement. It is 100% recyclable, aligning with green building principles.

Typical Applications

Marine Structures: Piers, seawalls, offshore bridges, platforms.

Infrastructure: Coastal bridges, tunnels, water treatment plants, and chemical plants.

Building Sector: Substructures (foundations, basements), buildings in perpetually damp environments, and landmark structures requiring utmost durability.

Repair & Retrofit: Rehabilitation of Existing Concrete Structures.
