Seismic Steel Materials, Strength in Tremor

Hyundai Motor Group contributes to the enhancement of the safety of buildings through its R&D for construction structural materials.
The H Core, which absorbs the impact from an earthquake and provides some flexibility against the tremor is the first seismic steel brand of South Korea
and the fruit of years of research efforts. In addition to the connotation implied in the brand name, ‘supporting the core in a safer manner,’
the name also indicates the commitment to become the ‘core’ of a safer South Korea.

With the increased frequency of powerful earthquakes throughout the world, more attention is being paid to the ‘seismic steel materials’ which delay the collapse of the building and minimize the damages it sustains.

Seismic steel materials are high-performance steel materials that can absorb the impact of an earthquake and respond to the tremor with more flexibility.
Compared to ordinary steel materials, they are more reliable, so that the architect may build the building as he/she intends.

Also, the superior energy absorption, resistance to impacts, and welding performances protect the building more safely from impacts from outside.

Also, the yield strength (the limit at which a deformed material can be restored to the original shape) and the yield ratio (the indictor of the extent of deformation reinforcement of a steel material) are designated specifically, so that the collapse of the building in a severe impact such as an earthquake can be delayed, providing more time for the people inside to escape.

Hyundai Motor Group and Hyundai Steel succeeded in developing seismic H-beams for the first time in South Korea, taking the leading role in developing seismic steel materials.

Also, we recently developed the entire set of KS standards for seismic rebars, while establishing a wide variety within the seismic steel portfolio, including steel plates and steel pipes.

With such technical capabilities, we launched the seismic steel material brand, H-Core, which will keep our buildings safe from earthquakes in South Korea.

Our products are used not only in South Korea but elsewhere such as thermal powerplants in foreign countries and the No.2 Antarctic Base, where the structures are exposed to extreme conditions, gathering more brand values for our products.

With H-Core, Hyundai Motor Group will be the leader for adding the ‘value of safety’ to buildings not only in South Korea but also the entire world.

Key Tech

For a building to survive an attack of massive energy, as in an earthquake, it is necessary to ensure not only the strength but also the energy absorption capacity of the materials.
H-core’s superior energy absorption capacity compared to ordinary steel materials prevents it from being broken by an external force easily and allows it to support the load with flexibility.

  • Reliable Performance of the Steel Materials

    The technology to control the performance of steel materials, including the lower and upper limits of strength, so that buildings may be built as the architect intends.

  • Plasticity

    With a low yield ratio and a low elongation rate allowing a higher energy absorption capacity, the steel material does not break up easily and supports the load with more flexibility.

  • Guaranteed Resilience against Impacts under colt temperature

    Absorbs energy well even in an extreme low-temperature condition.

  • Superb weldability

    The superb welding capacity allows a good bonding performance between structural materials, enhancing the safety of the building structure.
