Quality Control:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing or Cold Rolling, On line inspection
5. Heat Treatment: SR, A, N
6. Straightening/Cutting to specified length/Finished Measuring
Inspection
7. Quality Testing in own lab with Tensile Strength, Yield
Strength, Elongation, Hardness, Straightness, etc.
8. Packing and Stocking.
