Key Features
Hotdip Galvanized Thread Bars are heavy-duty steel bars with continuous threading across their entire length and coated with a thick layer of zinc through the hot-dip galvanization process. Built to endure extreme weather conditions and resist corrosion, these thread bars are ideal for structural and load-critical applications in outdoor and marine environments.
Hot-dip galvanizing protects against rust, chemicals, and salt spray, making it ideal for outdoor use.
Designed to perform in high-stress applications such as bridge anchoring and seismic systems
Allows for flexibility in cutting and fastening at any point without the need for custom threading.
Available in standard or customer-defined lengths with optional end-threading or chamfering.
These high-performance thread bars are used across various industries, including:
Bridge & Highway Construction – for foundation anchoring and concrete reinforcement
Pre/Post-Tensioning Structures – including dams, tunnels, and large-scale infrastructures
Marine & Coastal Installations – withstands moisture, saltwater, and corrosion
Transmission Towers & Utility Poles – for high-tension fastening
Earth Retention & Anchoring Systems – such as soil nailing, rock bolts, and retaining walls
