What AJU Steel does

AJU Steel is a South Korea-based B2B steel materials manufacturer founded in 1995 and headquartered in the Gumi Industrial Complex, Gyeongsangbuk-do. The company is a wholly-owned subsidiary of diversified conglomerate AJU Group and employs 501-1,000 people. AJU Steel specializes in color-coated and surface-treated steel products, offering what it describes as the world's only integrated portfolio of steel surface design manufacturing methods: Dprint (Roll-to-Roll digital inkjet printing on steel), Gprint (gravure roll printing with high-definition clear coating), and Sprint (Korea's first hybrid digital + silk-screen 4-color printing line). It has also developed a proprietary Big Picture AI Upscaling technology for super-size high-resolution printing.

The company's product portfolio spans three layers: electronic substrates (IMS/HCCL/pMCCL metal-copper clad laminate for OLED TV modules and power electronics), surface finishes (SUSlike stainless-look, SUSlike PET, GLAS:TEEL glass-steel composite, SUMC, DOI PCM/HG Metallic Print, CFM for OLED), and architectural products branded Atex (elevator skins, fire doors, facade panels, louvers, partitions, wallsteel, glass panels, DM Panel, DM Board). It also produces structural steel for solar, smart-farm, and general construction applications.

AJU Steel generates revenue through hardware sales of these specialized steel materials, selling directly to home appliance manufacturers (refrigerators, washing machines, ovens), electronics OEMs (OLED TVs), construction and architecture firms, and industrial/infrastructure customers. Distribution is direct B2B via corporate sales team and website inquiries; no public pricing is disclosed. The company maintains an IR function with earnings reports and disclosures, operates a bilingual Korean/English website, and serves primarily the Korean market with global B2B channel designation. It has received Smart Factory Excellence (2022), Technology Innovation (2020), and Carbon Neutral Leading Plant (2025) recognitions.

Broad incumbents

• Tata Steel: Global integrated steel producer with a meaningful color-coated steel and appliance-grade steel business (Tata Steel BSL/Tata Steel KZN). Comparable to AJU Steel in color-coated products for appliance and construction end-markets, primarily serving different geographic markets.
• Hyundai Steel: Major Korean steel manufacturer producing color-coated and galvanized steel products for construction, appliances, and automotive. Overlaps with AJU Steel in coated steel and architectural steel categories, though Hyundai Steel operates a much broader and more integrated product portfolio.
• ArcelorMittal: World's largest steel producer with extensive color-coated and galvanized steel operations (including the former Arcelor and Dofasco/Indesco businesses). Overlaps with AJU Steel in color-coated steel for appliances and construction at global scale.
• Voestalpine: Austrian specialty steel and coated products manufacturer with a strong focus on high-end surface-treated steel for appliances, automotive, and architecture. Comparable to AJU Steel's premium coated/printed product portfolio, particularly in architectural and appliance segments.
• POSCO: Korea's largest integrated steelmaker and a global leader in coated and galvanized steel products. POSCO competes with AJU Steel across color-coated steel, surface-treated products, and architectural/automotive applications, but at vastly larger scale and with captive raw material supply.
• Nippon Steel Corporation: Japan's largest integrated steelmaker with a global coated steel and surface-treated products business. Competes with AJU Steel in premium coated and printed steel for appliances, electronics, and architecture across Asia.

Direct peers

• SeAH Steel: Korean steel company producing coated and structural steel products for construction and industrial applications. Direct peer to AJU Steel in the Korean coated/structural steel market, serving overlapping appliance and construction customers.
• KG Steel: Korean producer of color-coated and galvanized steel products serving construction and appliance manufacturers. Closely comparable to AJU Steel's core product mix of coated steel plates with decorative finishes for Korean OEMs.
• Dongkuk Steel Mill: Korean steel manufacturer producing color-coated steel sheets, galvanized products, and architectural steel. Directly comparable to AJU Steel's core color-coated steel and architectural products business, particularly in Korean construction and appliance end-markets.

Regional players

• JSW Steel Coated Products: Indian producer of color-coated and galvanized steel products for appliances, construction, and industrial applications. Comparable to AJU Steel's coated product portfolio, though primarily serving the Indian subcontinent rather than Northeast Asia.
