Panchakanya Steel was created in 1982 with 415 grade rebar and afterward brought new technology from Germany, a technique that is Thermo Mechanically Treated (TMT) for the first time in Nepal in 2002. Ever since its debut, TMT has been the industry standard for all rebars in Nepal. Panchakanya Steel is the Best Steel in Nepal.


Panchakanya Group's commitment to excellence in quality production was first recognized in 1998 when the Nepal Bureau of Standards (NS) awarded Panchakanya Steel the first NS mark and certificate in the country, and in 2001 when Lloyds' Quality Assurance Register awarded Panchakanya Steel the ISO: 9001:2008 certification.


Since its founding, Panchakanya Steel has focused on delivering world-class quality and the latest technological advancements back to the country. In 2020, the business will introduce 500 XD and 550 XD grades in keeping with its commitment to quality and innovation.


All Panchakanya billets are of prime materials having a specification of Carbon 0.17 - 0.23%, Manganese 0.70 - 0.90% and Supler Phosphorous 0.035% max.


The Amazing Advantages of Rebar

  • Higher bond strength: Rebar and surrounding concrete form a stronger connection. Automatic milling machines are used to replicate the ribs' shape and profile, which produces ribs that are consistent and accurate, and hence provide uniform strength.
  • Excellent bendability: Due to the controlled process of manufacturing XD rebar under temp core technology, the tough outer surface and the softcore of XD results in rebar with excellent values of bendability
  • Superior weldability: As the name suggests, XD rebar is made from low carbon and carbon equivalent materials. In order to provide optimum weldability, the thermomechanical treatment is properly controlled.
  • Higher corrosion resistance: Thermal mechanical treatment is precisely controlled to produce a homogeneous and thick martensitic rim that is totally free of the internal dress. The martensitic rim of XD rebar enhances corrosion resistance and fatigue strength.
  • Super seismic resistance: Strength and ductility are combined in an unmatched way. XD rebar is capable of supporting seismic design in an acceptable manner. Energy dissipation was found to be improved for each cycle when columns in an RCC structure were tested for resistance to seismic stresses; this indicates that the joints are highly flexible.
  • Superior Rib Design: The new transverse and increased ribs in XD gives better bond strength with concrete.
  • Value for Money: XD rebar’s extra strength, higher elongation, and higher UTS/YS yield stress ratio give extra value to your investment.

What is Rebar?

Since concrete is very weak in tension, but powerful in compression, steel reinforcing bars, or rebars, are used to increase the tensile strength of concrete. Due to its high thermal expansion coefficient, steel is only utilized as reinforcing steel.


Types of Steel Reinforcement Bars

1. Mild Steel Bar

The mild steel bars have a flat, circular surface. They come in sizes ranging from 6 mm to 50 mm. You may use them to create column spirals, for example. You can also use them to create expansion joints, where the bars must move in a metal or paper sleeve. They are easy to cut and bend without causing any damage to the product or environment.

The lack of a strong connection between concrete and mild steel makes it unsuitable for structural constructions like bridges and other large structures.


2. Deformed Steel Bar

Deformed steel bars feature ribs, lugs, and indentations on the surface, which decreases mild steel bar slippage, and concrete and rebar bind well. Compared to other rebars, it has superior tensile characteristics. These bars are available in pieces with a diameter ranging from 6 mm to 50 mm.


Types of Deformed Steel Bars

1. TMT Bars (Thermo Mechanically Treated Bars)

In reinforced cement concrete (RCC) construction, Thermo Mechanically Treated Bars are high-strength hot-treated steel bars. As a result of its improved characteristics, including strength, ductility, welding ability, and bendability, MS steel bars now meet worldwide quality requirements.

Characteristics of TMT Rebars

  • Better ductility and malleability
  • High yield strength and toughness
  • More bonding strength
  • Earthquake resistance
  • Corrosion resistance
  • High thermal resistance
  • Economical and safe in use
  • No loss in strength at welded joints
  • Ordinary electrodes used for welding the joints


2. High Strength Deformed Bars

They are cold-twisted steel bars with projections or deformation on the surface that give them high strength and tensile strength. This material is often utilized in construction as a means of reinforcement. Four to fifty millimeter diameter bars are available.


Characteristics of HSD Rebar

  • Low carbon value - HSD Bars have lower carbon levels, resulting in good ductility, strength, and welding ability.
  • Superior bonding strength - HSD bars are well known for their excellent bonding strength when used with concrete.
  • Welding capability - Since these bars have lower carbon content, they have 100% welding capability than conventional bars.
  • High tensile strength - HSD bars feature high tensile strength. They offer great assets in the construction process, where a lot of bending and rebending are required.
  • Wide application range - These bars have a wide application range like in building residential, commercial, and industrial structures, bridges, etc.
  • Satisfactorily malleability - Minimum weight and maximum strength and suitable for both compression and tension reinforcement.


3. Other Types of Rebars

According to the substance used to make rebars, several varieties of rebars exist


1. European Rebar

Manganese is used in the manufacture of European rebar, which is pliable. If you live in a region where earthquakes, hurricanes, or tornadoes are likely to occur, you should not use these products. This rebar is inexpensive.

2. Carbon Steel Rebar

They're composed of carbon steel, as the name implies, and are frequently known as black bars because of their carbon color. Rebar corrodes, which has a negative effect on the concrete and structure. Black rebar is one of the finest alternatives because of its tensile strength ratio and low price.

3. Epoxy-Coated Rebar

Bar with an epoxy coating is black rebar. 70 to 1,700 times more corrosion resistant than steel with the same tensile strength The epoxy coating, on the other hand, is extremely sensitive. The corrosion resistance of the coating decreases as the damage to the coating increases.

4. Galvanized Rebar

Despite the fact that galvanized rebar is only forty times more corrosion resistant than black rebar, its covering is more difficult to damage. Epoxy-coated rebar is superior in this regard. But it's also more costly — by roughly 40 percent — than epoxy-coated rebar.

5. Glass-Fiber-Reinforced-Polymer (GFRP)

Carbon fiber is used in the manufacture of GFRP products. As it is formed of fiber, it cannot be bent. It is very corrosion resistant and expensive compared to other types of rebar.

6. Stainless Steel Rebar

Stainless steel rebar is the most expensive reinforcing bar available, about eight times the price of epoxy-coated rebar. It is also the best rebar available for most projects. However, using stainless steel in all but the most unique of circumstances is often overkill. But, for those who have a reason to use it, stainless steel rebar is 1,500 times more resistant to corrosion than a black bar; it is more resistant to damage than any of the other corrosive-resistant or corrosive-proof types or rebar, and it can be bent in the field.
