TECHNOLOGY

Our state-of-the-art Integrated Steel plant in Raigarh, Chhattisgarh uses the Turbo Quench Technology-led process of steel manufacturing. Each MSP TMT Bar 500D Grade produced through this process is rolled from in-house manufactured billets and is controlled through online PLCs for extra strength and durability.

The thermo mechanical treatment has three main stages

Quenching

The bars are passed through Turbo Quench cooling pipes and are rapidly water-quenched for a definite time, depending on the bar size and rolling speed. This hardens the surface, forming an outer layer of Crude Martensite and Austenite Core.

Tempering

After leaving the quenching line, the core of the rebar remains hot compared to the outer surface. It is not allowed to cool outwards from the core, converting the Crude Martensite to Tempered Martensite.

Cooling

The bars are then allowed to cool naturally on cooling beds, where the Austenite Core is transformed into ductile Ferrite-Pearlite. The resultant product exhibits high ductility and strength.

4X ADVANTAGE

4X ADVANTAGES

4x Strength

MSP TMT bars provide excellent strength with high elongation and yield, to give your construction a
longer life.

4x Flexibility

The tough outer surface and the ductile core of MSP TMT Bars make them flexible and extra bendable thereby aiding ease of construction, strength and added durability.

4x Tolerance

These bars with hardness of its outer surface and low carbon content have high elongation, which makes them superior in terms of tolerance and fatigue resistance.

4x Earthquake Resistance

Withstanding earthquakes, resisting fire or rust, defying the effects of time, these TMT bars give all-round protection to your constructions, for a lifetime.

QUALITY CONTROL

High-tech computer aided testing facilities in our NABL certified laboratory at our Integrated Steel Plant in Raigarh is used to carry out all the necessary quality checks,thereby ensuring standardisation of all product batches as per BIS 550D Grade specified quality parameters.

This is a 3 stage process involving checking and grading of raw materials, in-process quality checks and batch testing of finished products.

Receipt and checking of raw materials: The materials received from our Steel Melting Shops are tested on multiple counts before they are forwarded to the rolling mills

In-process quality checks: During rolling, the temperature of the bars are recorded stage-wise to ensure rolling at optimum and controlled temperatures.

Batch testing of finished goods: Post rolling, the finished units are tested in batches basis multiple Industry certified quality standards to generate Product Test Certificates and segregated accordingly with product tags.

PROPERTIES

Bending Properties

MSP TMT Bars have excellent bending properties due to the unique ductility (elongation values) obtained by employing the German Turbo Quench Technology.

Corrosion Resistance

Controlled water-cooling prevents the formation of coarse carbides, which have been cited as the main cause for the corrosive nature of common TMT bars.

Cost Effective

Compared to ordinary grade TMT Bars, MSP TMT Bars 550d ensure a cost saving of upto 18% on constructions.

Better Metallurgical Properties

Using best-in-class raw materials, and an end-to-end controlled manufacturing process with optimal temperature control systems ensures better metallurgical properties.

Perfect Roundness

Tensionless rolling through the loop scanner system ensures reduction of the oval shape, which is generally present in traditional rolling mills. The automatic system ensures consistent, uniform properties and a precise round shape.

Earthquake Resistance

MSP TMT Bars have high fatigue resistance to dynamic/seismic loads due to its higher ductility. This makes MSP TMT bars most suitable for use in earthquake-prone areas.

Fire Resistance

Because of their high thermal stability, MSP TMT Bars are marked as preferred choice for use in high temperatures (4000.C – 6000.C) applications.

Weldability

MSP TMT Bars with carbon content less than 0.25% can be used for butt and other weld joints without reduction in strength at the joints.

Higher Bonding Strength

Owing to the uniform rib pattern, MSP TMT Bars ensure better bonding strength with concrete. This gives higher strength to the structure and hence a longer life.

Finer Grain Structure

Size reduction from billet to the bars is done gradually in multiple stages for better and consistent grain structure. Refined and finer grain structure gives better metallurgical properties to the bars for longer life.

Strain Ageing

Due to the unique scientific manufacturing process and chemical composition, bars show no level of brittleness either during welding or cold deformation of welded joints.

Precise Gauge Control

Gauge Control System ensures precise and accurate weight of the bars by controlling gauge of the bars automatically between stringent tolerances.

PROCESS QMS

Process Quality management is at our core when it comes to manufacturing our wide range of products. A rigorous Quality Management System conforming to ISO 9001:2015 standards helps us maintain a benchmark in production quality.
