Quality assurance:

1. Assurance of raw materials.

All the raw materials we purchased are from local major mill, such as POSCO, BAOSTEEL AND TISCO etc. Compared with our competitors who sourced raw materials from small mill, our products have better appearance and more stable mechanical properties ,moreover the lifetime would last 3-5 years more long than the usual ones.

2. Welding procedure

• welding process has strict production process and operation guide book
• welding consistent, smooth, neat
• welding products without sand holes, porosity ,ensure that no leakage.
