"POSCO-Box pillar (P-Box) and Reinforced Concrete Beam Jointing Method (No. 868)" that were developed by POSCO and its customer companies have been designated as a new construction technology by the Ministry of Land, Infrastructure and Transport, POSCO said on Aug. 7
POSCO has developed the P-Box bonding method jointly with POSCO E&C, Halla, Hanyang and Hoban, comprehensive construction companies, to meet the needs of customers in the construction industry, such as the increase of earthquake-resistant design buildings and eco-friendly values.
POSCO also supports steel use technology to make P-Box products with high-strength steel for Dukam Technology, a steel customer company, to help improve the technology and increase sales of its customers.
The new technology, which connects horizontal reinforced concrete beams to concrete-filled P-Box steel pillars, can reduce construction costs by 10 to 15 percent from the existing reinforced concrete method, and also reduce carbon emissions by more than 1.5 percent, making it eco-friendly, a POSCO spokesman said.
Unlike the existing reinforced concrete method, which requires a single layer to be stacked, P-Box steel pipes will be stacked three stories at a time, with a height of 15 meters, reducing the construction period drastically.
"We succeeded in mass-producing HSA600 materials a year after POSCO started researching technologies based on materials and technology, and developed P-Box bonding method over three years to provide solutions to the construction industry," said Kim Jin-won, a senior researcher at POSCO Steel Solution Research Institute, which developed the technology.
