POSCO STEELEON said on the 24th that it signed a contract to supply materials for a hyperscale data center construction project in Australia with global IT corporations.
The supplied material is ALCOSTA steel, a hot-dip aluminum-coated steel sheet characterized by excellent corrosion resistance and heat resistance even in high-temperature and high-humidity environments.
As steel for data centers, it has fire safety and long-term durability. It was designed to suppress "zinc whiskers (Zinc Whisker)" that can occur with conventional galvanized steel sheets.
Zinc whiskers are small, conductive zinc crystals in the form of whiskers that grow on zinc-coated metal surfaces and can cause circuit board short circuits if they break off or detach and become airborne.
POSCO STEELEON's ALCOSTA steel was assessed to withstand the high heat generation, power loads and environmental stresses of data centers while ensuring long-term stability and reliability.
ALCOSTA steel is expected to be used for the white space walls where racks (Rack) storing IT equipment such as servers, storage and network switches stacked vertically inside data centers are housed.
POSCO STEELEON did not disclose the counterparty to the contract or details such as supply volume and price. In Australia, various global IT corporations, including Amazon Web Services, Microsoft and OpenAI, are pursuing hyperscale data center projects.
A POSCO STEELEON official said, "The application of our products to a core infrastructure project of global IT corporations is the result of our technological prowess and quality competitiveness being recognized," and added, "We will continue to expand the supply of premium steel, focusing on high value-added markets such as data centers."
