Top12 prevents reinforcement corrosion in extremely chloride-loaded tunnel emergency walkways

Advantage: No corrosion-related repairs during the planned service life, no congestion due to construction sites, minimization of life cycle costs

Recommended product: Top12

Top12 prevents reinforcement corrosion in tunnel walls with high chloride loads. Top12 can be used here selectively in external reinforcement layers and thus in combination with B500B. 

Advantage: No corrosion-related repairs during the planned service life, no congestion due to construction sites, minimisation of life cycle costs. Further reduction in the amount of reinforcing steel possible by exploiting the higher strength of 670 MPA for Top12 bar material.

Recommended product: Top12

Thanks to its alloy composition, this stainless super austenitic steel has a high resistance to numerous organic and inorganic acids. It also offers a tensile strength of at least 800 MPa.

Advantage: High resistance to pitting corrosion and stress corrosion cracking
