Ministry of Industry Expands Standard Sizes of Core Steel Material 'H-Beam' to 95 Types

[Sejong=Asia Economy Reporter Kwon Haeyoung] The National Institute of Technology and Standards under the Ministry of Trade, Industry and Energy announced on the 7th that it will promulgate a revision of the Korean Industrial Standard (KS D 3502) to expand the standard sizes of 'H-beams,' a core material in construction sites, from 82 types to 95 types.

H-beams are essential steel materials for building structures, offering superior seismic performance compared to other construction materials and shorter construction periods. However, their sizes have been limited, causing inefficiencies in design. The National Institute of Technology and Standards will add 8 large sizes and 5 of the most commonly used 400mm-class sizes. The expansion of large sizes aligns with the trend of ultra-high-rise and large-scale construction industries, and the increase in 400mm-class sizes is significant as it broadens the range of product options.

The construction industry expects that this expansion of standard sizes will allow for the appropriate use of various specifications of H-beams to ensure safety and resolve economic issues caused by design inefficiencies.

Lee Seungwoo, Director of the National Institute of Technology and Standards, stated, "This expansion of standard sizes is a revision of national standards that responds to the changes and demands of the demand industry, such as ultra-high-rise and large-scale construction," adding, "We will continue to closely monitor market changes and promote the establishment and revision of standards for our companies, industries, and citizens."
