Krakatau Posco

What Krakatau Posco does

PT Krakatau Posco is an integrated steel manufacturer established in 2010 as a 50-50 joint venture between PT Krakatau Steel (Persero) Tbk, the Indonesian state-owned steelmaker, and POSCO of Korea. The company operates a greenfield integrated steel mill in Cilegon, Banten — the first Blast Furnace facility in Indonesia — with a stated annual capacity of 3 million tons. Commercial production began in early 2014, and the mill covers the full production flow from ironmaking through steelmaking, continuous casting, and hot rolling, integrated via computer-based factory systems with real-time monitoring and predictive analytics.

The company's core product portfolio consists of steel slabs (semi-finished), steel plates, and hot rolled coils (HRC), certified to international standards including SNI, ASTM, JIS, EN, MS, and API-5L. Specialized offerings include seismic-resistant steel grades (SN400, SN490), weathering steel, marine grade steel, and high-strength welded structural steel. The first IATF 16949:2016 certification in Indonesia (issued June 2023 by Lloyd's Register) positions the company as a strategic supplier for automotive OEMs. Quality control is supported by an AI-powered Surface Defect Detector (SDD) deployed at the Hot Rolling Plant, and the site holds seven classification society certifications (ABS, DNV, LR, KR, ClassNK, BV, RINA) plus ISO 9001, 14001, 45001, and 17025 accreditations.

Krakatau Posco operates a direct enterprise sales model with inquiries routed through a Jakarta commercial office at Pacific Century Place SCBD. Customer segments include infrastructure and construction, shipbuilding, oil and gas pipeline, automotive, re-rolling mills, and pressure vessel manufacturers, serving both domestic Indonesian and export ASEAN markets. The company is designated as an Objek Vital Nasional (Strategic National Object), holds Authorized Economic Operator (AEO) certification, and is recognized as the largest integrated steel mill in ASEAN. Revenue is not publicly disclosed; the company publishes financial statements and investor materials but is a private joint venture. In 2026, the company announced planning for a second phase of investment covering capacity expansion and development of value-added automotive steel products.
