- precast concrete components
- columns
- warehouses
Increasing strength and reducing steel quantities
Top700 solves several challenges other concrete reinforcement steels cannot. Thanks to the higher yield strength of >700N/mm2, Top700 overcomes technical boundary conditions, such as space problems with the reinforcement or aesthetical challenges, such as reduction of the concrete cross-section. And it comes head-on with economic advantages, because due to its higher strength, up to 40% less steel is required, saving money on several ends: reduced quantity, reduced machining efforts, less transport. The latter also a welcome factor from an environmental standpoint.
- Yield strength of >700N/mm2
- higher strength rebar - 40% stronger than conventional B500B
- Allows reduction of steel needed due to higher strength
- Allows slimmer and more streamlined structures
- Steel bar

Take a look at how Top700 compares to regular B500B
High-strength Top700 means less steel for the reinforcement
New possibilities of architectural design are opening up: slimmer construction with better use of space and less weight. The workload in prefabrication and on site is reduced because less steel is needed. It is easier to comply with the standard values for maximum rebar content in highly reinforced components. Reinforced concrete construction with Top700 does not require any special properties of the concrete.
