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 and Cold Rolling, on line inspection

5. Heat Treatment, +A, +SRA, +LC, +N, Q+T

6. Straightening-Cutting to specified length-Finished Measuring Inspection

7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc

8. Packing and Stocking.

• 100% of our steel tubes are dimensionally checked
• 100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
• 100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
