The agreement and the parties involved
Posco and GS Group signed a strategic memorandum of understanding on Wednesday in Gangnam, Seoul, to collaborate in the AI data center sector, according to The Korea Herald. The ceremony was attended by, among others, Posco Chairman Lee Hee-geun and GS Group Vice Chairman Hong Soon-ki. The agreement is a memorandum, not a binding contract: the two companies announced that they will soon form a joint working group to define implementation plans and international expansion strategies.
The collaboration model calls for GS Group to lead domestic AI data center projects, while Posco participates from the design phase. This is the main novelty: the steel company does not merely supply materials at an advanced construction stage, but applies its early supplier involvement program to offer tailored solutions already in the design phase.
Why it matters: construction timelines and efficiency
According to the source’s account, profitability in AI data center development depends on two factors: reducing construction times and maximizing power supply and cooling efficiency. Faster timelines allow operators to bring computing capacity into service on schedule and accelerate revenue. This is where the declared complementarity between the two groups comes into play: on one hand Posco’s specialized materials, on the other GS Group’s infrastructure value chain.
Posco intends to use its dedicated AI data center range, which includes corrosion-resistant PosMAC alloy plates, electromagnetic shielding materials and high-efficiency electrical steels, presented as solutions to increase durability and reduce construction times and maintenance costs. The company also says it wants to apply its experience in power generation at steel plants to heating, ventilation and air conditioning systems for data centers.
On the GS side, the announced organization calls for GS E&C to lead planning, power supply, engineering and construction, and GS Caltex to be responsible for liquid cooling solutions. This is a division of roles communicated by the parties, not results already achieved: no investment amount, project location or capacity, or timeline has been indicated at this time.
The remarks and open questions
Lee Hee-geun said that the rapidly expanding AI data center market represents a future growth engine for steel and materials demand, and that the partnership with GS Group aims to consolidate the two companies’ position in the global market. This is a statement of intent, reported by the source, that is not accompanied by quantitative targets or verified market forecasts.
The announced plan calls for an initial domestic phase, followed by use of Posco’s international steel network and GS Global’s overseas channels to target high-demand AI markets in North America and Asia. Several aspects remain to be clarified: the non-binding nature of the memorandum, the absence of financial figures and deadlines, and the fact that the benefits cited by the two groups — greater profitability and operational stability of projects — are the parties’ assessments and not measured results. The news should therefore be read as the start of an industrial collaboration to be verified in its implementation developments.
