Excellent cathodic corrosion protection

The outstanding corrosion protection of corrender is significantly higher than that of conventionally galvanized steel strip.

Significantly improved protection against white rust

Conventionally galvanized steel strip shows substantial signs of white rust after 48 hours in the salt spray test. Contrastingly, the corrender surface is practically free of white rust after the same amount of testing time.

Significantly improved protection against red rust

The superior protective properties of corrender become particularly apparent in tests for red rust. Because a passive layer is formed, red rust formation is delayed significantly. No signs of red rust formation are recognized, even after 500 hours.

Reduced metallic coating thickness

The superior protective effect of corrender leads to two possibilities:

  • Increased corrosion protection with same metallic coating thickness
  • Same protection with significantly reduced metallic coating layer
