Mechanical Testing
Laboratory

All PowerSteel TMT rebars ranging from 8mm to 25mm undergo rigorous physical and mechanical testing in our in-house mechanical lab.

Physical Checks Include:

  • Rib size measurement
  • Rib spacing verification
  • Dimensional accuracy and surface inspection

Each sample is carefully marked and prepared before testing.

Universal Testing Machine
(UTM)

Our Universal Testing Machine (UTM) is used to evaluate the core mechanical properties of the steel we produce.

Tests Conducted:

  • Tensile strength
  • Yield stress
  • Percentage elongation
  • Bend and re-bend tests

These tests ensure that every bar delivers the required strength, flexibility, and durability expected from premium structural steel.

Quality Assurance – Wire &
Galvanizing Processes

Our Quality Assurance Department monitors multiple in-process checks, especially for wire products.

Electro-Galvanizing Process:

  • Wires are coated using electro-galvanizing, where a protective metal layer is deposited for corrosion resistance

In-Process Quality Analysis:

  • Titration tests
  • Metal stripping tests
  • Coating thickness verification per unit area

These ensure uniform coating and long-term performance.

Wire Strength &
Performance Testing

At Tarmal Steel, we manufacture annealed and galvanized wires that meet strict performance parameters.

Parameters Tested:

  • Yield strength
  • Tensile strength
  • Elongation

Every batch is tested to confirm it complies with required standards before reaching the market.

Our Commitment

All checks, tests, and verifications are conducted in-house with precision and consistency.
 This is how we ensure that every product leaving Tarmal Steel reflects reliability, safety, and long-term performance.

Because quality isn’t inspected at the end — it’s engineered from the start.
