POSCO is rolling out its Greenable H-Beam, a structural steel product designed to cut embodied CO2 in buildings and infrastructure while keeping standard beam geometry and performance. The H-shaped sections are part of POSCO's Greenable portfolio, which bundles lower-carbon steels for construction and renewable energy projects. By focusing on verified emissions reductions per ton rather than radical new shapes, POSCO aims to let engineers and developers adopt greener steel without rewriting existing design standards. The Greenable H-Beam targets the structural footprint of buildings, bridges and industrial plants, where steel profiles account for a significant share of embedded carbon. POSCO positions it as a drop-in alternative that keeps familiar cross-sections and fabrication behavior, so contractors can use it without retooling production lines. Pricing is contract-based with a premium over conventional beams, reflecting the additional effort to lower emissions during production. Competition in this niche is growing, with European producers like SSAB and ArcelorMittal introducing similar low-carbon structural steels. POSCO's Greenable H-Beam must stand out on availability, consistent mechanical performance, and documentation that meets international certification norms. For now, the product mainly addresses early adopters among large developers and infrastructure owners willing to pay more upfront for lower lifecycle emissions.
