Dongkuk CM Develops World's First 'Dual Stone' Technology Replicating Natural Stone Texture

Combination of Surface Treatment and Digital Printing
Texture Realized with Pattern Length Extended to 10 Meters
30 Years of Durability with Highly Corrosion-Resistant Steel Sheets

Dongkuk CM, a color steel sheet manufacturing subsidiary of Dongkuk Steel Group, announced on October 17 that it has developed the world's first 'Dual Stone' technology, which authentically replicates the texture and color of natural materials such as natural stone.

Dongkuk CM has launched two new products utilizing the Dual Stone technology: 'Double Stone' and 'Marble Stone.' Both products are currently undergoing patent application. Double Stone realistically reproduces the texture and surface color of stone, while Marble Stone features the rough feel and patterns of stone powder particles.

Dual Stone combines Dongkuk CM's proprietary surface treatment technology with digital printing technology, enabling pattern lengths of up to 10 meters and creating a sense of depth and naturalness similar to real natural materials. When the company's highly corrosion-resistant coated steel sheets (GIX and GLX) are applied, the products can maintain their quality for up to 30 years without discoloration or abrasion, even under extreme weather conditions such as heatwaves or heavy snow.

Dongkuk CM expects this technology to broaden the range of choices in the construction materials market and strengthen its position as an eco-friendly steel alternative to natural materials. The process does not require quarrying, and no silica (quartz powder) dust is generated during processing, which enhances recyclability.

Choi Woochan, Head of Dongkuk CM’s Technology Research Center, stated, "Dual Stone is a high-value specialty product that can replace expensive natural construction materials, and it is a technology that can only be realized in Korea. We hope it will grow into a competitive product capable of overcoming tariff barriers and market stagnation."
