Dongkuk CM develops color-coated steel sheet with 10 times better condensation-delay performance

[Financial News] Dongkuk CM has developed a functional color-coated steel sheet that delays condensation ten times more effectively than existing products. It also offers vibration-damping and antifungal properties, and the company plans to apply it to industrial facilities such as HVAC ducts and distribution panels at AI data centers.
Dongkuk CM said on the 12th that it had developed a multifunctional color-coated steel sheet, DK Shield (pronounced “D-K Shield”), using special coatings and multilayer coating technology.
Tests by the Korea Testing & Research Institute (KTR) found that the new product’s condensation-delay performance was about 10 times that of existing products. Condensation occurs when droplets form on a metal surface due to a temperature difference, and can cause equipment corrosion or electrical defects. Managing condensation is particularly important at AI data centers, which operate large HVAC systems and distribution panels.
Vibration-damping performance also improved over existing products. In an evaluation by the Korea Testing Laboratory (KTL), the loss factor, which indicates the damping characteristics of vibration energy, measured 1.12% for conventional products and 2.13% for the new product. Dongkuk CM also obtained a test report under KS D 0076, which evaluates the vibration-damping characteristics of vibration-damping steel sheets.
The product’s antifungal function was tested in accordance with the international testing standard ASTM D5590, and an accredited test report was obtained.
Dongkuk CM designed the product’s coating structure so that its condensation-delay, vibration-damping and antifungal functions can be combined to suit each customer’s operating environment. The company is looking to expand its applications beyond AI data centers to livestock facilities and is also considering using the product as a material for automotive interiors and parts.
