QUALITY
ASSURANCE
To adhere to highest standards of Quality Assurance, the material undergoes the below mentioned tests:
To ensure the highest standards of Quality Assurance, the material undergoes visual inspection, dimensional checks, mechanical and chemical testing, non-destructive evaluation, and performance testing. These tests collectively verify the material’s integrity, accuracy, and suitability for its intended application.
CHEMICAL COMPOSITION :
To confirm to IS 2831:2012 ,a meticulous Chemical analysis of every lot of billet is carried out in our chemical and Spectro lab. The billets thus tested are then moved for rolling.
MECHANICAL PROPERTIES :
The mechanical properties of bars are tested through –
Section Weight : ‘Weight per Meter’of the bars as per
IS:1786:2008 is checked by taking out sample after every
thirty minutes. Standards weight is always maintained
within BIS tolerance.
- Load Test : Yield Load, Ultimate Tensile Load and Elongation are tested using UTM of 100 Ton capacity.
- Bend Test : As per sizes specified in IS code, the bend test is carried out by bending the bars on mandrel.
- Re-bend Test: Bars are bent at an angle of 135°, kept in boiling water at 100°C for 30 minutes and then bent back at an angle of 157.5°.
DEFORMATION AND
SURFACE CHARACTERISTICS :
The ribs are cut through automatic CNC Rib Cutting
Machine to get precise, uniform in shape ribs. Checks
are carried out at regular intervals.

AR Value (Area of Ribs) :
Calculation of the AR Value is the
Bond Test.

Bond Test.
ETCHING TEST :
Bar ends are finished and polished like glass finishing and
dipped into Nitrole to visualise three distinct rings –
dipped into Nitrole to visualise three distinct rings –
- Outer Core of Tempered Martensite
- Middle Core of Mixed Bainite
- Inner Core of Ferrite Parlite. After all these the tests, Tagging, Packing, Storage and dispatch of material happens.
