The introduction of high yield strength deformed bar as reinforcing steel has revolutionized the world of reinforced concrete design. Ribbed - Torsteel bar or in short TORSTEEL - a high strength cold - twisted deformed bar, originally developed by TORISTEG STEEL CORPORATION of Luxembourg, Germany is now a widely accepted re-bar in most countries of the world.

TORSTEEL is produced from mild steel billets with limited carbon content (0.30% max.) by controlled cold - twisting of hot-rolled deformed bar with its characteristic configuration. Each bar is cold-twisted individually. The cold twisting works the steel beyond its elastic limit and a bar with normally inherent defect breaks during twisting. Every piece of Torsteel bar thus undergoes this severe automatic test during its twisting process. Use of Torsteel bar results in 40% steel saving and 30% saving in steel cost compared to mild steel round bars of 66,718 psi (460 N/mm2) yield point.

• 65% higher yield strength
• 100% higher bond strength
• Satisfactory weld ability due to limited carbon content
• Lesser crack width of RCC members
• 20% extra factor of safety due to elimination of definite yield point
• Net economy in reinforcing cost: 35% in tension, 30% in compression
• End hooks not required due to 100% higher bond capacity
• Saves labor, transportation, supervision costs due to reduction in steel consumption
• Being a licensed product the quality is guaranteed
