QUALITY CONTROL

MSP Structural undergoes rigorous quality checks, time and again, to guarantee finest products to our customers. High tech computer-aided testing equipment at its laboratories carries out all the tests accurately. The inspections ensure correct:

  • Chemistry
  • Casting
  • Strength
  • Hardness
  • Dimension Standards

Stages of checking and quality control receipt and checking of raw materials

The materials received from our Steel Melting Shops are tested for their chemical composition and surface defects. Only the accepted quality is forwarded to the heating furnace.

In- process quality checks

During casting, the temperature of the structural steel products is recorded at the time of entry into the structural mill till the finishing stand, which ensures optimum and controlled temperatures.
