To solve common problems encountered by overseas buyers including inconsistent material grade, unqualified coating thickness, delivery delay, missing documents and rust during transportation, original manufacturer Jiangsu Zhongersheng sorts out professional risk avoidance guide to help global buyers purchase steel stably and efficiently. 1. Confirm material grades in advance: Specify stainless steel grade (201/304/316), carbon steel grade (Q235/Q345) and galvanized zinc coating weight to prevent project loss caused by wrong materials. 2. Request original MTC certificates: Formal manufacturers provide material test certificates for every batch, supporting customs clearance and project acceptance worldwide. 3. Anti-corrosion solution for coastal humid projects: Choose heavy hot-dip galvanized steel, 316 stainless steel or PVDF PPGI for seaside rainy areas to reduce long-term maintenance cost. 4. Clarify processing & packaging requirements early: Vacuum anti-rust and reinforced wooden packing are mandatory for ocean freight; mark drawing tolerance clearly if cutting or bending processing is required. 5. Verify supplier manufacturing & export qualifications: Prioritize manufacturers with self-owned factory and full import & export licenses, who can provide complete customs documents in one stop to avoid export delays. All goods shipped from Jiangsu Zhongersheng pass triple inspection, equipped with full MTC certificates and standardized anti-rust export packaging. Our professional foreign trade team tracks orders whole-process to avoid all procurement risks for overseas clients.
