High Ductile Rebar; First Time in Nepal and For Nepal.

Rhino 500D Rebar is the first and the only steel rebar in grade Fe 500D with superior ductility introduced in Nepal. It also marks the beginning of the New Industry Quality Benchmark for Steel Rebars in Nepal. With superior ductility and earthquake resistance properties, Rhino 500D compared to other normal grade rebars is highly suitable for applications in areas and region highly prone to seismic risks like Nepal. Rhino 500D is the only new generation rebar that truly fits in to the need of seismic resistant construction in Nepal.

Because Safety Matters! Rhino 500D Steel Rebar Matters!

As the largest integrated steel company in Nepal, Jagdamba Steel has carried forward the challenge and responsibility of staying the very best, and in keeping with the tradition of being a leader, we have innovated and moved a step ahead now with the introduction of Rhino 500D Steel Rebars, Redefining steel making, the company has developed Fe 500D grade Rhino Rebars through the 100% special quality raw material specially imported and manufactured through automated controlled production process, quality control management route. It is the first time in Nepal that Rebars have been produced through this process to meet the changing and more stringent needs of our country and seismic zone. With High Ductility and superior earthquake resistance properties, Rhino 500D Rebar assures highest standards in quality and safety of construction and lives.

Chemistry Controls Steel Quality…We Control the Chemistry of Steel!

The chemistry and thus the properties of the Steel Bars get compromised by the presence of the harmful impurities like Sulphur, Phosphorous and Carbon, in extreme weather conditions. Through the advanced steel rebar making process the impurities are restricted in Rhino 500D Rebars to a maximum value at; Sulphur and Phosphorous 0.40%, Carbon at 0.25%. To control the chemistry we ensure the highest standard in quality of the raw materials, the billets, blooms are exclusively imported from world class steel companies like TATA Steel, JINDAL Steel and IISCO. For stronger assurance the raw materials undergo spectrometer quality testing at the state of the art automated lab before going in to production. The 3 level automated Controlled Production Process with controlled environment ensures the maintenance of the chemical and physical properties in compliance to NS: 191 and BIS (IS: 1786:2008) Certification Standards.

Superior Process and Product Quality

Why Rhino 500D Rebars are superior to traditional Rebars in the market? The answer is Superior Making and Precision in the maintenance of physical and chemical properties. Since Sulphur & Phosphorous (S&P) are harmful impurities in Steel, High level of Phosphorous can lead to ‘Cold Shortness’ in Steel a condition in which the steel tends to become very brittle under extreme cold conditions and thus highly vulnerable to cracking. High level of Sulphur can lead to ‘Hot Shortness’ in steel, a condition in which the melting point of steel gets lowered thereby reducing its strength dramatically under high temperature conditions. However, the levels of S&P can be achieved only through advanced Steel making. The low levels of S&P as specified in NS and BIS specification are impossible to achieve under normal Steel making and Rebar production process. But due to the practice of import of raw materials, the billets, and blooms from world class steel companies and manufacturing through the state of the art automated and controlled Rebar production technology and stringent quality controls at every step right from the input of the raw materials to the output, the finished Rebars comply 100% to the quality standards of Fe 500D grade specification of NS: 191 and BIS (IS: 1786:2008) Certifications.

The Process and Technology

Rhino 500D High Ductile Rebars are manufactured at the most modern rolling mill in Nepal at Simara, Bara. The Rebars are manufactured with latest ‘TMT Technology” through the 3 level Controlled Production Process to offer quality standards exceeding the NS:191 and BIS (IS: 1786:2008) certification Standards.

 

Raw Materials

Producing Rhino 500D Premium High Ductile Rebars require special Fe 500D Grade Billets and Blooms which are exclusively imported from world class steel companies line TATA Steels, JINDAL Steel, IISCO, and SAIL. The sourcing of high quality raw materials is followed by stringent quality test to ensure that only the raw materials with right composition go in to production.

High Sulphur Effect, Phosphorous Effect and Carbon Effect

Rhino Fe 500D Rebars have lower percentage of Carbon, Sulphur, and Phosphorus. The low carbon content ensures sufficient ductility and superior weldability for all types of welding without preheating. The impurities like Sulphur and Phosphorous tend to decrease the strength of steel in extreme weather conditions as hot shortness and cold shortness.

Steel Rolling

Most modern automated Rolling Mill applying latest “TMT Technology” to produce Rhino 500D Rebars with consistently high quality in every single Rebar.

Automated Re-heating Furnace

The Automated Gasified Re-heating Furnace not only ensures Uniform Heating but also ensures less fuel consumption.

TMT-Thermo Mechanical Treatment

The Rebars Undergo Thermo Mechanical Treatment in 3 successive stages:

  • Quenching
    The hot rolled bar leaving the final mill stand is rapidly quenched by a special water spray system. This hardens the surface of the bar to a depth optimized for each section through formation of martensitic rim while the core remains hot and austenitic.
  • Self-Tempering
    When the bar leaves the quenching box, the core remains hot compared to the surface, allowing heat to flow from the core to the surface, causing tempering of the outer martensitic layer in to a structure called ‘Tempered Martensite’. The core still remains austenitic at this stage.
  • Atmospheric Cooling
    This takes place on the automatic cooling bed where the austenitic core is transformed in to ductile ‘Ferrite-Pearlite’ Structure. Thus the final structure consists of an optimum combination of a strong outer layer (tempered martensite) with a ductile core (ferrite-pearlite). This gives Rhino 500D its unique combination of higher ductility and strength.

Working towards future

Rhino 500D looks to bring to Nepal, a name that showcases quality and gives Nepal, the steel it needs. The revolution of steel technology and the assurance of the people, is Rhino 500D Premium High Ductile Rebar.


 

With the low levels of Sulphur and Phosphorous, the Carbon levels are maintained at much lower than the specifications which results in its excellent ductility, high strength, high bendability, better corrosion resistant and superior weldability and earthquake resistant.

The modern, automated and precision in quality control approach of manufacturing creates a combination of strength and ductility that far exceeds the minimum limit specified in the standards; NS: 191 and BIS (IS: 1786:2008). The typical values for Tensile Strength are Min 580 as against the Min 565 and elongation 18% as against 16% in the standard values. The superior values of strength and ductility is the guarantee of Rhino 500D Rebar for higher levels of safety for years.

Excellent Bonding with Concrete

Rhino 500D Rebars have precise, parallel and uniform rib pattern engraved through computer controlled notch making machines resulting in excellent bond strength with concrete. The computer controlled production ensures 100% uniform rib patterns across the length of the Rebar. This is in contrast to ordinary Rebars in which the ribs are cut manually and are non-uniform.

Excellent Bendability

The special Microstructure of Rhino 500D gives it excellent bendability (in spite of High Strength). The bar can be bent easily and sharply. Rhino 500D Rebars can be bent to exact angle unlike ordinary Rebars as desired by the design around mandrels and is much smaller in diameter than what is specified in NS: 191 Standards and BIS (ISI:1786:2008). This gives a better advantage by facilitating easy bending, making work easier and faster at construction sites.

Superior Weldability

Due to its low Carbon Equivalent, Rhino 500D has Weldability which is superior to other normal Rebars. It can be butt-welded or lap-welded using ordinary rutile coated electrodes of matching strength. In case of manual arc welding no pre-warming or post-welding treatment is necessary.

Greater Earthquake Resistant Properties

Due to high UTS/YS Ratio Rhino 500D Rebar offers high strength and ductility and thereby excellent Earthquake Resistant property which helps in minimum damage to the structure and hence minimizes casualties.

More Superior Elongation/ Ductility

Fe 500D produced under controlled manufacturing process and have excellent bendability. It is worth mentioning that the minimum specified elongation for Fe 500D is 16%. They have lower percentage of carbon, Sulphur, and phosphorous that ensures high/superior ductility compare to other Fe 500 grade bars.

Greater Resistance to Fire

The quenching and the self-tempering treatment at a temperature of approximately 650° C results in consistent and thick layer of tempered martensitic-ring on the outer surface of the rebar imparting higher capacity to retain strength at elevated temperatures.
