Quality Assurance

Quality Control

Our quality control department is staffed with highly qualified and experienced metallurgists and chemists, which has three distinct wings:

The department is equipped with:

JO Steel Holdings PLC Consists Of Four Units

JO Steel Holdings PLC operates four units to ensure product quality.

Spectrometric Laboratory Unit

It has the latest version of Spectrometer for instant analysis of 22 elements in steel.

Chemical Laboratory Unit

This laboratory is equipped with machineres and equipments to provide chemical analysis facilities.

Mechanical Testing Unit

The mechanical properties, including strength and ductility, are measured by the Universal Testing Machine (UTM).

Metallographic Laboratory Unit

A metallurgical microscope has been set up in this unit to ensure the correct metallographic properties of products.

Tests For Quality Assurance

All data from testing and inspection are fed back to the production unit and stored by the quality control department for the improvement of quality. The customer liaison wing (marketing and sales division) handles every complaint from any customer. Our quality control team continuously monitors the production process at each stage under the guidance of Metallurgical Engineers.

Tensile Test

We perform Tensile Tests to determine properties such as Young's modulus, ultimate strength, and percentage elongation.

Compression Test

We perform Compression Tests to determine important mechanical properties such as yield strength, yield point, Young’s Modulus, and the stress-strain curve.

Transverse Test

We perform Transverse Tests to measure transverse tensile strength, yield strength, proof stress, elongation, and reduction of area.

Brinell Test

We perform Brinell Tests to test the force of a hard steel ball on the calculated curved area of the indentation formed, to determine hardness.

Bend Test

We perform Bend Tests to determine the ductility or resistance to fracture of our steel bars.

Re-bend Test

After the Bend test, we immerse the steel in 100°C hot water for 30 minutes and then bend it again to determine its resistance to fracture.

Analysis of Chemical Composition

We perform chemical composition analysis for a wide variety of purposes, which helps us to control overall quality.

Certifications & Recognitions

We are certified and recognized by national and international standard organizations.
