THE ROLE OF STEEL IN SAFETY
What is concrete reinforcing steel (construction iron)?
Concrete Reinforcing Steel (CRS) is the iron used in a structure made of reinforced concrete (béton armé). It is the main material that ensures a structure’s safety and strength.
What is the purpose of reinforcing steel (construction iron)?
The main purpose of reinforcing steel (iron) is the durability and stability of the structure, especially in the event of strong earthquakes. Specifically, reinforcing steel (bars, meshes) reinforces the load-bearing structure (frame) of the building and prevents the concrete from breaking or cracking at critical points, such as columns, beams, slabs etc. In the event of seismic activity the steel absorbs seismic energy, preventing damage to the building.
Why is the quality of reinforcing steel so important?
The increased seismicity observed in Greece requires strict adherence to the engineer’s design, as well as use of steel of high strength and ductility, according to the ELOT 1421 specifications.
SD steel more than covers the specifications of the latest European and Greek regulations thanks to the increased absorption of energy, resulting in safer concrete structures.
What is the cost of reinforcing steel (iron) compared to the total cost of a building?
The contribution of reinforcing steel (iron) in the total cost of a building is in the order of 4-5%. It is obvious that the relation between the quality of reinforcing steel and safety does not allow any cost-cutting or compromise in the quality of the steel used. For example, in a building with a typical construction cost of €1,000/sq.m., the cost of steel ranges between €40-50/sq.m. The decision to select SIDENOR SD steel instead of cheaper steel of dubious origin does not affect the cost by more than €2/sq.m.
How can I identify SIDENOR SD steel?
SIDENOR stamps its reinforcing steel with an embossed SD mark, so that it can be easily identified by the supervising engineer, constructor or owner.
Why should I buy SD reinforcing steel by SIDENOR?
- Its focus on quality has made it a leader in the Greek market.
- It offers the safety and trust associated with the largest steel manufacturing plant in the Balkans and South-East Europe.
- It has been established as the main steel supplier for highly demanding projects with strict specifications related to the country’s infrastructure.
- It has a complete radioactivity control and detection network, both for raw materials as well as for the end products, ensuring that the final products are completely free of any radioactivity.
