1.Material Area: Make sure the raw material loading smoothly. We use Q195/Q235 steel strips for the pipe raw materials. We have full black annealed, regular black annealed and bright annealed surface treatment. The performance are the same, just different in color.
2. Production Area:
We use the machine which can produce 5000tons/month.
Oiled during the production to avoid pipe rusty.
Cutting during the production to save time and have a perfect slit.
3. We have 2-3 workers stay in production ending to make packing.
3 QC check the pipe quality all the time. Once he sees some broken will find it right now and repair it.
