オリーブグリーン亜鉛メッキ鋼管
1. We use high quality raw materials for the olive green galvanized steel tube. All raw materials are supplied from internationally known steel makers.
2. Each batch of raw material is checked for both chemical and mechanical properties, according to specifications.
3. During the cold drawing process, our inspectors check every bundle three times: once at the beginning of the process, once during the middle, and finally, at the end of the cold drawing process.
4. During the final heat treatment, every bundle has the surface checked, as well as mechanical properties through samplings.
5. Non-destructive testing and manual inspection for each tube ensure the 100% quality rate before galvanization
