Our Quality
CONTROL

The company always ensures to enhance its customer experience; therefore there are in-house facilities like OES (Optical Emission Spectrometry) and Lab facilities for Macro Analysis of the products. This special quality of ARS 550D TMT bars is also labeled as ARS 550D "Fe 550D”. Here, “Fe” signifies ferrous denoting iron, “550” indicates the minimum yielding strength and “D” indicates ductility. The high ductility amplifies the shock withstanding capacity and makes ARS 550D earthquake and fire resistant up to 500 Degree Celsius. Driven by values, commitment, and a strong urge to deliver the best to its customers, ARS 550D ensures to surpass the quality control specifications enlisted by BIS.

ARS 550D Features

High Tensile Strength and Ductility

Going forward ARS has taken one more initiative of launching the Mobile Tech Express, an “On-road Testing Lab” with demo quality testing for TMT Rods & ARS 550D.

To provide technical guidance in building construction a value-added service to individual house builders, contractors, and engineers. Customers can avail of guidance and suitable advice about the selection of construction materials.

Interact with our qualified Civil Engineer on your queries at your building site regarding TMT Bars. Bend/Rebend test, Martensite (Ring) test will be conducted live at your site to demonstrate the quality of ARS 550D. Watch Videos of Multi-Point Testing conducted every day at ARS Factory to know about it before ARS 550D reaches your site.

Laboratory & TESTING

  • BEND & REBEND TEST

    Bend and rebend test is a testing method to check the quality of steel. Rupture and cracks if any present in a steel bar can be checked in this test. These test results are plotted in a bend/rebend test chart to identify the crack or rupture in the steel bars.

  • MARTENSITE &RING TEST

    Martensite (Ring) test is a quality control test to check the hardness, ductility, and strength of steel by analyzing the rings formed during the test.

  • TENSILE TEST

    Tensile test which involves testing the tensile strength of steel is done in Universal Testing Machine (UTM) which is used to test the compressive strength and the tensile strength of steel.

  • QUENCHING PROCESS

    Quenching is a process of rapid cooling of a heated metal in water, oil or air to obtain certain material properties. For steel, hardness is achieved by this process.

  • BILLET MANUFACTURING

    Freshly made steel which is in the form of a rectangle or a metal bar is referred to as steel billet. Billets are be produced either directly by continuous casting or extrusion or indirectly by hot rolling in billet mills.

  • SPECTRO ANALYSIS TEST

    Spectro analysis test involves identification, sorting, and analysis of steel during incoming inspection, production, and before delivery.

Frequently
Asked
questions

What is Thermo Mechanical Treatment?

Thermo-Mechanical Treatment (TMT), is a metallurgical process that integrates work hardening and heat-treatment into a single process.

Since TMT bars undergo thermo-mechanical treatment, they are extremely ductile and have high tensile strength. This makes it usable for every shape. It also provides great resistance to fire, earthquake, and corrosion. It is also easy to transport because of its lightweight build.

TMT bars are divided into various grades – Fe415, Fe500, Fe500D, Fe550 and Fe600. The number denotes the yield strength of the TMT bars and the letter ‘D’ denotes the ductility. Each grade has different properties and applications and therefore it is important to choose the right grade by knowing its application and usage.

TMT bar which contains a higher amount of Sulphur makes it prone to fire and a high amount of phosphorus causes fatigue to the bars.

Often due to the interaction of the rebar with moisture and air, the surface of the rebar develops a reddish colour which is being misunderstood as corrosion. Reddish rebar can be used for construction without any hesitation as long as they are in proper physical shape, weight and strength.
