Why MELBN Products

Higher Strength

QST Rebars have higher strength and are available in all grades. So, now you can have high strength rebars and thus can easily cuts overall cost by optimizing consumption.

Bending Properties

QST Rebars have excellent bend properties due to the unique ductility (elongation values) obtained by employing the German "Thermex" Techonology.

Corrosion Resistance

Controlled water cooling prevents the formation of coarse carbides, which has been cited as the main cause for the corrosion prone nature of common bars. Another reason for better corrosion resitance is the absence of surface stresses caused by the cold twisting and Tor steel process.


QST Rebars require 15-30% less usage than ordinary bars for same work with 5% more cost. This results in overall saving of 10-20%.

Better Metallurgical Properties

Perfect temperature control system to ensure better metallurgical properties.

Perfect Roundness

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

Precise gauge

Control systems ensure precise accurate weight of the bars by controlling gauge of the bars automatically between stringent tolerance.

Customised product

Chemical metallurgical and physical properties as per design requirements of clients are given by Melbn. Additional relevant services are offered as per specific customer requirement.

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.

Higher Bonding Strength

Melbn QST Rebars with their uniform and precise rib pattern ensure better bonding strength with concrete. This gives higher strength to the structure and hence a longer life.

Better weldability

Melbn QST rebars bars carbon content less than 0.25% can be used for butt and other weld joints without reduction in strength at the joints.

Fire resistance

Melbn QST Rebars have higher thermal stability.They are the preferred choice in case of elevated temperatures of 400 - 600 degrees centigrade applications (chimneys,fires).

Earthquake Resitance

Melbn QST Rebars have high fatigue resitance due to its higher ductility. This makes it most suitable for use in earthquake prone areas.


Due to very high elongation values and consistent properties throughout the length of rebar, Melbn QST Rebars have excellent workability and bendability.

Strain Ageing

Due to unique, scientific manufacturing process and chemical composition, Melbn QST Rebars show no tendency of brittleness either during welding or cold deformation of welded joints.
