Six years after application, we returned to Nansha Bridge to inspect the results 🔎
Spanning the Pearl River estuary and linking Guangzhou and Dongguan, the Nansha Bridge is exposed to humidity and salt spray, which can accelerate corrosion.
Hempel A/S developed a specialised protection system for the bridge’s largest section, helping to provide:
🛡️ long-lasting corrosion protection with our advanced Avantguard® technology;
🛡️ reduced maintenance frequency and lower lifecycle costs; and
🛡️ strong colour retention and gloss performance even in severely polluted environments.
The site inspection showed that the steel structure and protective coatings remained in excellent condition.
The Nansha Bridge is one of more than 200 major steel bridges Hempel has helped protect across China. Each one builds on decades of experience in long-term corrosion protection.
