Dongkuk CM, a specialized company for coated and color-coated steel sheets under the Dongkuk Steel Group, announced on the 12th that it has developed "DK Shield," a high-functionality color-coated steel sheet equipped with condensation delay, vibration damping, and anti-mold features.
DK Shield is a product that applies special functional coatings and multi-layer coating technology to delay the condensation phenomenon where water droplets form on metal surfaces, while also suppressing vibration and mold growth. It was developed for application in industrial facilities such as air conditioning ducts in artificial intelligence (AI) data centers.
According to test results from the Korea Testing Laboratory (KTR), DK Shield's condensation delay performance is at a level 10 times that of existing products. AI data centers can experience condensation due to temperature differences with the outside environment during the operation of large-scale air conditioning equipment and switchboards. As accumulated water droplets can lead to equipment corrosion, contamination, or failure, condensation management is crucial.
The vibration damping performance is also approximately twice that of existing products. In an evaluation by the Korea Testing Laboratory (KTL), the loss factor, which indicates the degree of vibration energy absorption, was 2.13% for DK Shield, higher than that of general products (1.12%). Dongkuk CM has also secured a KS D 0076 test report regarding its vibration control and damping performance.
The anti-mold function was verified through testing in accordance with the international test standard ASTM D5590. This is expected to allow for an expansion of application scope to industrial buildings and livestock facilities where hygiene management is critical.
As AI data centers grow larger and denser, stable operation of cooling and air conditioning equipment has become increasingly important, leading to greater interest in materials that enhance equipment durability and maintenance efficiency.
Dongkuk CM designed the coating structure to allow for combinations of condensation delay, vibration damping, and anti-mold functions depending on customers' usage environments. The company is also considering expanding its application fields to automotive interior materials and parts.
Choi Woo-chan, head of Dongkuk CM's research institute, stated, "It is a multifunctional color-coated steel sheet that implements three functions in a single product," adding, "In particular, it is a product specialized for AI data center air conditioning ducts where condensation and vibration management are critical, and we will expand its application to various industrial facilities."
