Kay2 XENOX

Uniquely built with a ribbed design, Kay2 XENOX TMT Bars assist in making powerful bonds with the concrete. The Hexagonal pattern lays a firm foundation to the building and adds resilience to the structure. Used across all earthquake-prone areas in the country, Kay2 Steel’s TMT Bars are made to ensure seismic resistance. In addition to this, they are built keeping in mind all kinds of hazards including fire and corrosion of metal through time. This is why the bars are made with innovative technology for anti-corrosion and fire resistance. The thermo-mechanical-treatment along with the sum of internal angles (720 degrees) ensures the high tolerance and anti-fatigue nature of the bars. Also, this allows the bars to have a rigid cover having a softcore increasing the ductility, bendability, weldability, formability, and compressive and tensile strength. This makes the TMT Bars crack resistance and an apt product for construction purposes.

Advantages

  • Made from billets
  • Excellent surface finish and Quality
  • Premium quality raw materials used
  • Latest rolling techniques
  • Strict metallurgical control

Principles

You must check out the following essential qualities while purchasing TMT Bars:

  • It must bend easily.
  • Its ribs must be sharp for the strongest bonding with cement.
  • It must have good combination of strength & ductility.
  • The weight standards of TMT Bars per meter must be as per ISI standard.
  • TMT Bars must have been manufactured by an ISI & ISO certified company.
  • Every meter length of TMT Bar must bear its company stamp.
Features

Bond Strength

The Splicing Rib Design pattern of Kay2 XENOX TMT Bars offers an average of 2.7 times higher bond strength compared to ordinary bars bond strength and are specially designed to ensure excellent bondage between the bar and the surrounding concrete. The strong compression and tension in reinforced concrete produces an everlasting bond and adds longevity to the structure.

Superior Bendability

Kay2 XENOX TMT Bars have outstanding bending and re-bending properties without any occurrence of cracks. The tough outer surface and a ductile core ensures that the composite works efficiently and cracks are under control. This results in rebars with extremely high bendability offering shape to the perfect construction. These bars can be bent around mandrels much smaller than those specified in IS: 1786.

Better Weldability

Kay2 XENOX TMT Bars offer superior weldability than conventional bars due to its low carbon equivalent. Its excellent formability and weldability absorbs seismic waves and increases safety. It can easily be butt-welded, or lap welded using ordinarily coated electrodes of similar strength. No pre-warming or post-heat treatment is necessary for manual arc welding either.

Corrosion Resistance

Corrosion of reinforcing bars depletes the service life of the concrete structure. Kay2 XENOX TMT Bars are designed and produced with the latest technology to protect reinforcing steel bars against corrosion from the high-alkalinity of pore water. The compact rib pattern (Hexagonal Molecular Bonding) provides better physical protection so that the corrosion rate decreases and increases the life of the structure.

High Temperature Resistance

At Kay2 Steel, we use standard materials while treating the steel with a high melting point to make it stable, durable, and reliable in the face of extreme temperatures. This allows Kay2 XENOX TMT Bars to retain more than 80% of its ambient temperature yield strength at 300 degrees Celsius and 40% at 500 degrees Celsius.

Dimensional Tolerance

Our Quality Control measures include measurement of chemical and mechanical properties and close dimensional tolerances for a superior quality product. Kay2 XENOX TMT Bars are supplied with section weight lower than the nominal, within the BIS specification. They are guaranteed to be lesser than the nominal mass & less than 1% heavy to provide various design advantages and application benefits.

Seismic Resistance

Kay2 XENOX TMT Bars reveal superior seismic resistance properties during simulated earthquake conditions induced on reinforced concrete, beam, column and joints to evaluate performance under repeated reverse-loading with inelastic strains. The advanced processed steel has a mesh grip for a stronger steel cement bond. Its superior physical and chemical properties soften the earthquake generated forces acting upon it and escape the deformation and damage.

Economics of Savings

Kay2 XENOX TMT Bars are new generation rebars with Hexagonal Molecular Bonding and usable yield stress which is above that of Fe-500 grade of IS:1786. Hence, their use based on the working stress or limit state method as per IS:456, would result in substantial savings in steel costs as compared to a typical T-Beam floor built with Mild Steel Bars.
