Applications

Top12

Top12 is an innovative reinforcing steel with a superior corrosion resistance and the lowest life cycle costs in its class. Top12:

  • is a high-alloy material of grade 1.4003 with higher corrosion-resistance than conventional reinforcing steel, as it contains at least 12 percent chromium by mass.
  • requires no special handling and can be processed conventionally.
  • is approx. four times more resistant to chlorides than conventional reinforcing steel. This reliable protection against corrosion can extend the service life of buildings many times over.
  • requires very little concrete cover due to its higher corrosion resistance in the event of chloride or CO2 impact.
  • in its geotechnical version with higher yield strength, makes the usual anchor system sleeve superfluous, as it offers the necessary protection for temporary and permanent anchoring of protection level 2 in any subsoil - even in aggressive groundwater.

Durability tailored to the application requirements

Corrosion caused by chlorides is the most common form of reinforcement deterioration. Chlorides penetrate the concrete and lead to corrosion initiation at a certain chloride concentration at the reinforcement level. Depending on the corrosion resistance of the reinforcement, damage occurs more quickly or more slowly. Varying alloy content and the surface properties of the stainless steel allow for proactively modifying corrosion resistance of the steel.

In order to improve the reliability and durability of structures, taking into account the overall costs, optimized material selection is crucial. As the alloy content increases, not only does the resistance of stainless steel increase, but also the material costs. The aim is to select the reinforcement according to the corrosion stress and the desired service life in a balanced cost-benefit ratio.

Top12 is five times more corrosion-resistant

The secret of the excellent mechanical-technological material properties and high corrosion resistance lies in the steel production: the decisive factor is the targeted addition of alloys to the molten steel, including more than 12% chromium. The ribbed reinforcing steel is produced using a patented rolling process. After rolling, the steel is cooled in a controlled and targeted manner in order to maintain its excellent mechanical properties.

To increase the corrosion resistance in line with requirements, Steeltec pickles the Top12 after hot rolling - a further step to increase the corrosion resistance by a factor of five. Pickling removes the so-called rolling skin. This makes the bar surface smoother and more homogeneous and protects the ribbed steel from surface corrosion and pitting. While the conventional, unalloyed reinforcing steel B500B can withstand a chloride content of approx. 0.5 wt.%/z in the concrete, this value is up to five times higher with the Top12.

The result: mathematically no repairs over 100 years of service life

The formula for achieving the desired service life in construction is based on the following components: Concrete + sufficient concrete cover + Top12. Calculations for the prime example of a highway bridge center pillar show that with Top12, builders and operators can safely achieve the target service life of 100 years without repair measures. Without Top12, i.e. with conventional B500B, extensive repairs must be carried out at least once.

New EU steel safeguard measures change framework conditions for Steeltec

The European Union (EU) has adopted new steel safeguard measures that will enter into force on July 1, 2026. Duty-free import volumes into the EU will be reduced by 47% from 34.5 million tons to 18.3 mil-lion tons. Imports exceeding these quotas will be subject to a tariff of 50%, up from the previous rate of 25%. The measures apply to steel producers from third countries, including Switzerland, exporting products into the European Union. Steeltec AG, based in Emmenbrücke and part of Swiss Steel Group, is among the companies affected by the new regime.

Firmly anchored in the rock - Swiss Steel Group’s Top12 anchors secure a new section of road high above Lake Lucerne

100 years – that is the lifetime expected for the new section of the K2b cantonal highway between Vitznau and Gersau following its renovation and modernization. This is made possible in no small part by the Top12 special stainless steel from the Swiss Steel Group, from which the anchors for the retaining wall structure and support elements are manufactured. Over a hundred of these were drilled several meters deep into the steep rock face. They secure the walls and beams that support the new, 350-meter-long section of road. The structure is spectacular not only from a geotechnical perspective but also for everyone who drives over it and enjoys a breathtaking view of Lake Lucerne below.
