The global Hot-dip Galvanized Steel for Data Centers Market was valued at USD 2.05 billion in 2025. It is estimated to reach USD 2.51 billion in 2026 and is projected to grow to USD 7.77 billion by 2036, at a CAGR of 12.0% during the forecast period. This report offers a detailed look at the market, covering market dynamics, the regulatory and trade policy landscape, coating standards, pricing, the value chain, competitive activity, and future growth opportunities.
The market covers the sales value of hot-dip galvanized steel products used in data centers. It includes structural sections and plate, cable tray, ladder, and basket systems, strut, channel, and framing systems, roof deck and purlins, floor systems and pedestals, enclosures and containment, and fasteners and fittings. Both continuous galvanizing of coil, including zinc-aluminum-magnesium (Zn-Al-Mg) coatings such as Magnelis and ZAM, and batch galvanizing of fabricated steel are covered. Each product is counted once, at the level at which the data center project, its contractors, or its equipment makers buy it. Stainless steel, aluminum, pre-painted panels, electro-galvanized steel, rebar, conduit, and equipment housings are excluded.
Structural fabricators and building system suppliers buy galvanized sections, plate, deck, and purlins for the frame, roof, and plant yard. Electrical and mechanical contractors buy cable tray, strut, fasteners, and containment for data halls and electrical rooms, mostly through distributors. Server rack and IT cabinet makers buy galvanized sheet from steel mills. Market value is measured at the supplier selling price and assigned to the country of purchase, which for construction products is the country of the data center site. Rising AI capacity is the main source of demand, as the JLL 2026 Global Data Center Outlook expects about 100 GW to come online between 2026 and 2030.
The report examines market drivers, restraints, opportunities, and challenges, along with an impact analysis of market determinants over three periods. Coverage extends to the EU Carbon Border Adjustment Mechanism, U.S. Section 232 measures, coating standards such as ISO 1461, ASTM A123, and ASTM A153, zinc price dynamics, and energy cost pass-through in galvanizing. The value chain, Porter's five forces, and four case studies are also analyzed. In addition, it provides market forecasts in value, segment-level insights, and regional analysis across 5 regions, 22 countries, the Nordic Countries, and 4 rest-of-region groups.
Zinc and steel price volatility restrains market growth. According to the International Lead and Zinc Study Group (February 2026), the LME cash price of zinc averaged USD 2,870 per tonne in 2025. It reached USD 3,955.50 per tonne on October 30, 2026, according to Westmetall, about 38% above the 2025 average. Tariffs and trade measures that raise steel costs form a second restraint. Proclamation 10947 raised U.S. Section 232 tariffs on steel and steel derivatives from 25% to 50% in June 2025. In July 2026, the EU replaced its steel safeguard with a tariff-free quota about 47% below its 2024 safeguard quotas, with a 50% duty above the quota.
Low-carbon galvanized steel for hyperscaler embodied-carbon targets offers a significant opportunity. In September 2025, Microsoft agreed to buy near-zero emission steel from the Stegra plant in Boden, Sweden, for suppliers of its data center components. Zn-Al-Mg and heavy coatings for harsh sites offer a second opportunity, as new campuses move to hot, humid, and coastal locations. According to ArcelorMittal, Magnelis cable trays carry 310-430 g/m² of coating, against 800-1,000 g/m² for trays galvanized after fabrication. New galvanizing capacity and data-center-focused product lines offer a third opportunity. AZZ started a new kettle in North Texas in 2026 because of demand, and Nucor is building a sheet mill with two galvanizing lines in West Virginia.
Galvanizing kettle capacity, energy cost, and skilled labor remain major challenges. According to V&S Galvanizing (August 2025), an average kettle is about 40 ft long, so long or bulky members must be split or dipped in stages. The American Welding Society projected in August 2025 that the U.S. will need 320,500 new welding professionals between 2025 and 2029. Substitution by alternative coatings and materials forms a second challenge, mainly for light products inside the white space. Electro-zinc, powder-coated, stainless steel, and aluminum products compete for tray and enclosures in dry, climate-controlled rooms.
Key trends include the shift from galvanizing after fabrication to Zn-Al-Mg coil for trays and light outdoor framing. Prefabrication of support steel forms a second trend. Vertiv states that its SmartRun overhead assembly, which combines busway, piping, cabling, and containment, deploys up to 85% faster than stick-built methods. Consolidation among cable management and framing suppliers is a third trend. ABB and Niedax Group formed the Abnex cable tray joint venture in November 2024, and Prysmian completed its acquisition of Atkore in October 2026.
Based on product form, the market is segmented into structural sections & plate, cable tray, ladder & basket systems, strut, channel & framing systems, roof deck & purlins, floor systems & pedestals, enclosures & containment, and fasteners & fittings. In 2026, structural sections & plate are expected to hold the largest share, because every project needs frames, platforms, pipe racks, and plant steelwork. Caunton Engineering supplied 2,769 tonnes of beam and column steelwork for the 48 MW LHR21 data center of Vantage Data Centers in London. Cable tray, ladder & basket systems are expected to grow the fastest, as AI halls carry denser power cable, busway, and fiber.
Based on galvanizing process, the market is segmented into continuous hot-dip galvanizing and batch hot-dip galvanizing. In 2026, continuous hot-dip galvanizing is expected to hold the larger share, owing to the wide use of pre-galvanized coil in roof deck, purlins, indoor tray and strut, containment, and rack sheet. Batch hot-dip galvanizing is expected to grow faster, driven by heavy-duty ladder tray, outdoor structural steel, and fasteners that need thicker coatings.
Based on coating class, the market is segmented into standard coating class and heavy & extra-heavy coating class. In 2026, the standard coating class is expected to hold the larger share, because most galvanized steel in a data center sits inside a conditioned building. The heavy & extra-heavy coating class is expected to grow faster, driven by larger plant yards and by faster data center growth in hot, humid, and coastal regions.
Based on application area, the market is segmented into white space & electrical rooms, structural frame & envelope, and external works & plant yard. In 2026, white space & electrical rooms are expected to hold the largest share, owing to the tray, strut, containment, floor pedestals, and rack sheet installed in each data hall. External works & plant yard are expected to grow the fastest, driven by larger generator yards, chiller plant, on-site substations, and pipe racks at AI campuses.
Based on procurement route, the market is segmented into fabricator-supplied, service center & distributor, and mill-direct. In 2026, the fabricator-supplied route is expected to hold the largest share, because structural steel, platforms, and prefabricated skids are bought as engineered packages. The mill-direct route is expected to grow the fastest, as mills such as Nucor and POSCO sell deck, building systems, containment, and rack sheet directly to data center projects.
Based on data center type, the market is segmented into hyperscale, colocation, and enterprise & edge. In 2026, the hyperscale segment is expected to hold the largest share, owing to the scale of campuses that the largest cloud and AI companies build for their own use. The colocation segment is expected to grow the fastest, driven by wholesale build-to-suit campuses for hyperscale tenants and by new AI cloud providers that lease capacity.
In 2026, North America is expected to hold the largest share of the market, and the U.S. is the largest country market in every year of the forecast period. Primary U.S. markets had 9,432 MW of data center supply at the end of 2025, up 36% in one year, according to CBRE (March 2026). Section 232 tariffs favor steel made and galvanized within North America over imported coil and fabricated products.
Asia-Pacific is the second-largest region, with China as its largest market and India as its fastest-growing one. Google plans to invest USD 15 billion over 2026-2030 in a gigawatt-scale AI hub in Visakhapatnam. Europe ranks third, where Germany leads in 2026, the U.K. is expected to lead by 2036, and Spain grows fastest as grid limits push new construction away from the main hubs.
The Middle East & Africa is expected to register the highest growth during the forecast period. HUMAIN targets 250 MW online by the end of 2026 and 1.7 GW in 2027, according to Enterprise AM (September 2026). Saudi Arabia is the fastest-growing country, and hot coastal and desert sites in the Gulf call for heavy coatings and duplex systems. Latin America is expected to grow faster than the global market, led by hyperscale projects in Brazil and Mexico.
