What Millcon Steel does

Millcon Steel Public Company Limited (SET: MILL) is a Thai integrated long-steel producer and distributor founded in 1998 and listed on the Stock Exchange of Thailand since November 2007. The company operates across the full long-steel value chain through Electric Arc Furnace (EAF) billet production at its Green Mill project (backed by 5,000 million THB of BOI investment), Vacuum Degassing and FASTARCTM finishing, rolling mills in Bangkok and Rayong, and downstream steel product manufacturing. Its product portfolio under the MILL brand spans Deformed Bar, Round Bar, One Bar (a proprietary twisted deformed bar with helical threading for which Millcon is Thailand's sole producer), Wire Rod, Steel Pipe, C-Section, Galvanized Steel, and Billet, supplemented by value-added Cut&Bend processing services.

The company generates revenue primarily through B2B sales to Thailand's construction sector, serving large real estate developers (Supalai, Sansiri, AP, Noble Development, Lumpini), government infrastructure buyers (MRTA for multiple mass-transit lines, Department of Railways, Airport Authority of Thailand for Suvarnabhumi), large commercial projects (One Bangkok, Icon Siam, King Power Mahanakhon, The PARQ), and automotive OEMs via the Kobelco Millcon Steel joint venture with Kobe Steel of Japan. Distribution is carried out through an authorized dealer network across Thailand, direct B2B channels, and a regional footprint in Myanmar via the Millcon Thiha and Millcon Thiha GEL joint ventures in the Thilawa Special Economic Zone.

Millcon also holds strategic investments in adjacent verticals: scrap procurement (Sun Tech Metals, 99.99%), electrical equipment (I-Gen Engineering), steel pipe and profile production (Millcon Steel Pipe), construction material distribution (Saharat Construction Materials), solar power (Siam Solar Generation), logistics (B Logistics), venture capital (Moonshot Venture Capital), and the Builk.com construction technology platform. The company has been actively positioning for the low-carbon transition, securing Carbon Footprint Product Label certification in January 2024 and signing an MOU with Singapore's Meranti Green Steel in March 2026 to co-develop Green Steel production in Thailand and the Asia-Pacific region.
