Engineered for superior metallurgical properties, high productivity, and reliable operation — from 8mm TMT rebar to 12mm wire rod coils, at capacities up to 500,000 MTPA.
GPRM's TMT rebar mills and wire rod mills are designed ground-up for the demands of modern steel production. Every mill is engineered to deliver consistent bar quality, high rolling speeds, and minimal downtime — whether you're producing construction-grade TMT rebar or precision wire rod coils.
Our TMT mills incorporate advanced thermo-mechanical treatment systems that give the finished bars their characteristic combination of high tensile strength and ductility. The rapid quenching process creates a tough martensitic outer layer while preserving a soft, flexible ferrite-pearlite core — meeting IS 1786, BS 4449, and ASTM A706 standards.
For wire rod production, our mills deliver tight diameter tolerances and consistent coil quality at high speeds, making them suitable for downstream applications including wire drawing, fastener manufacturing, and cold heading.
Every GPRM TMT and wire rod mill comes with complete engineering support — from initial layout design through commissioning and post-commissioning optimization.
Two distinct product lines, both built with the same engineering discipline and attention to detail.
Produce high-strength TMT bars for residential, commercial, and infrastructure construction. Our in-line quenching system delivers consistent metallurgical properties across every bar in every batch.
Produce consistent-quality wire rod coils for wire drawing, nail making, fastener manufacturing, cold heading, and other downstream applications. Tight tolerances and smooth surface finish.
A GPRM TMT rebar line covers the complete production flow — each stage engineered for consistency, speed, and quality.
Our mills produce bars and rods that serve critical roles across construction, manufacturing, and infrastructure sectors.
TMT rebar for RCC columns, beams, slabs, foundations, and retaining walls in buildings and housing projects.
High-grade TMT bars for highways, flyovers, bridges, dams, and other large-scale infrastructure projects requiring seismic resistance.
Reinforcement bars for factory buildings, warehouses, power plants, and heavy industrial foundations.
Wire rod for downstream wire drawing, nail manufacturing, and fencing wire production.
Precision wire rod for bolt, nut, screw, and rivet manufacturing through cold heading and forging processes.
High-carbon wire rod for PC wire, PC strand, and spring wire used in pre-stressed and post-tensioned concrete systems.
Steel plants across India and beyond rely on GPRM TMT rebar and wire rod mills for their production lines.
GPRM TMT rebar mills are designed for sizes ranging from 8mm to 40mm diameter, covering the full range of construction-grade reinforcement bars used in residential, commercial, and infrastructure projects.
Our wire rod mills support production capacities from 100,000 to 500,000 MTPA for sizes 5.5mm to 12mm, with options for semi-automatic to fully automatic operation.
Thermo-mechanical treatment (TMT) is a process where hot-rolled steel bars are rapidly quenched with water immediately after the final rolling pass. This creates a hard outer martensitic layer while the core remains soft and ductile, giving TMT bars their characteristic combination of high strength and flexibility.
Yes. GPRM provides end-to-end TMT mill solutions including design engineering, equipment manufacturing, erection, commissioning, trial runs, and ongoing technical support.
