Welspun Shield Extra Ductile Fe 550 TMT bars are thermo-mechanically treated reinforcement bars engineered to deliver high strength with extra ductility for modern RCC design. The 40 mm diameter section offers excellent bond with concrete and optimised bar weight, making it suitable for both primary and secondary reinforcement in residential, commercial and infrastructure projects.Produced from quality billets in fully automated mills, the bars feature a tough outer martensitic layer and a softer, ductile core, providing superior energy absorption during dynamic and seismic loading. Controlled chemistry and process parameters ensure good weldability, corrosion resistance and consistent mechanical properties along the entire length of each bar.

Key Features

• High strength Fe 500 grade with extra ductility for safer structural performance
• Ribbed 40 mm profile offering strong mechanical bond with concrete and reduced slippage
• Thermo-mechanically treated (TMT) structure with tough outer surface and ductile core
• Good elongation values providing better crack resistance and seismic performance
• Optimised chemistry for good weldability and improved corrosion resistance
• Uniform sectional weight and length for accurate bar bending schedule (BBS) planning

Applications

• Footings, columns, beams and slabs in RCC buildings
• High-rise and commercial structures requiring ductile detailing
• Industrial sheds and warehouse foundations
• Infrastructure projects such as bridges, flyovers and metro structures
• Water tanks, retaining walls and other critical RCC elements
