Data Center Construction Materials Supply Chain Market Size, Share & Forecast to 2035

The Data Center Construction Materials Supply Chain Market is valued at USD 13.38 billion in 2026 and is projected to reach USD 24.33 billion by 2035, up from USD 10.62 billion in 2025, a CAGR of 8.64% from 2025 to 2035 (DC Market Insights estimate). What moves the money here is a metals price shock landing on a record build: US Census Bureau data show private data center construction put in place rising from USD 34.80 billion in 2024 to USD 49.74 billion in 2025 and to a seasonally adjusted annual rate of USD 96.46 billion in September 2026, while the Section 232 steel tariff went to 50% in June 2025 and, from 6 April 2026, to the full customs value of derivative products. The producer price index for steel mill products climbed 24% between December 2025 and September 2026, so every tonne of frame, deck and rebar in a new hall now costs more than it did when the campus was budgeted.

The market covers the shell, structure, envelope and site materials delivered to data center construction sites: structural steel and metal deck, ready-mix concrete and reinforcing steel, precast concrete, insulated metal panels and roofing, fire-rated gypsum and insulation, and aggregates, piles and site civil materials. The 2025 receipt is 12,000 megawatts (MW) of new IT capacity × USD 849,500 of shell-and-core materials per MW = USD 10.19 billion, plus USD 427.20 million of materials for expansions and rebuilds inside the 116,000 MW installed base. Mass Timber Hybrid structures grow fastest at 19.07% a year because Microsoft and Meta are piloting cross-laminated timber to cut embodied carbon, and Middle East and Africa is the fastest region at 13.87% as Gulf campuses move from plans to poured slabs.

Key Market Statistics: How Big Is the Data Center Construction Materials Supply Chain Market in 2026?

The Data Center Construction Materials Supply Chain Market reaches USD 13.38 billion in 2026, 26.01% above the USD 10.62 billion of 2025, as new IT capacity rises from 12,000 MW to 15,000 MW and tariff-driven steel prices lift the cost of each frame (DC Market Insights estimate).

• Materials per new MW rise from USD 849,500 in 2025 to about USD 859,900 in 2026, because tariff-driven steel prices outrun the savings from denser artificial intelligence (AI) halls.
• Owner-Direct Framework Agreements grow 13.47% a year, because hyperscalers now buy steel, concrete mixes and panels themselves to lock in supply and embodied-carbon limits.
• Precast Concrete Components grow 10.39% a year, faster than cast-in-place concrete, because precast and prefabricated systems cut site time on campuses that must energise in under two years.

Executive Summary: What Is the Data Center Construction Materials Supply Chain Market Worth?

The Global Data Center Construction Materials Supply Chain Market size was valued at USD 3.84 billion in 2020, reached USD 10.62 billion in 2025, and is anticipated to reach USD 24.33 billion by 2035, at a CAGR of 8.64% during the forecast period (DC Market Insights estimate).

Attribute	Detail
Historical period	2020-2024
Base year	2025
Forecast period	2026-2035
Market size 2025	USD 10.62 billion
Market size 2026	USD 13.38 billion
CAGR 2025-2035	8.64%
Market size 2035	USD 24.33 billion
Unit	USD million

The Data Center Construction Materials Supply Chain Market grew 22.57% a year from 2020 to 2025 as new IT capacity rose from 5,000 MW to 12,000 MW and steel prices doubled; growth slows to 8.64% a year to 2035 because new capacity flattens near 27,000 MW a year and AI halls pack more megawatts into each square foot of building. Average materials per new MW stay in a narrow band of USD 836,100 to USD 859,900 from 2026 to 2035, so capacity sets the volume and metals prices set the swing.

What Materials Does the Data Center Construction Materials Supply Chain Market Include?

The Data Center Construction Materials Supply Chain Market counts USD 10.62 billion of 2025 purchases of shell, structure, envelope and site materials at delivered price to the site, including fabrication of steel and casting of precast, but not installation labour.

Included

• Structural steel, joists and metal deck for data halls, mechanical yards and office blocks
• Ready-mix concrete and reinforcing steel for foundations, slabs and walls
• Precast concrete wall, floor and beam elements and tilt-up panels
• Insulated metal wall panels, roofing membranes and roof systems

Excluded

• Copper cable, busbar and other electrical materials, sized in the Data Center Copper Electrical Materials Market
• Mechanical and electrical equipment (generators, switchgear, chillers, uninterruptible power supply systems)
• Raised floors, containment and racks
• Installation labour, design fees and land

How the segments fit together

Every segment table splits the same total: six material types, four construction methods, three facility types and three procurement models each sum to USD 10.62 billion in 2025, and the five regions and the country rows reconcile to the same figure.

Why Do Data Center Construction Materials Supply Chain Market Estimates Differ?

The DC Market Insights figure of USD 13.38 billion for 2026 counts only shell-and-core materials at delivered price, which is about 16% of the USD 65.60 billion Data Center Construction Market of 2025.

Broader definitions of a data center construction materials supply chain add copper electrical materials, mechanical and electrical equipment, installation labour, logistics services or general contractor margin, and some count the whole construction budget, which multiplies the headline figure several times. Others count only one product family such as steel or cement. The land and shells these materials become are valued in the Data Center Real Estate Market, and design fees in the Data Center Design Market. This edition stays at the materials layer so that it adds up with the sibling reports on construction, copper and equipment without double counting.

Element	In this report	Why
Structural steel, concrete, precast, envelope, interior and site materials	Yes, USD 10.62 billion in 2025	Core shell-and-core purchases
Copper cable and busbar	No	Covered by the copper electrical materials report
Generators, switchgear, chillers	No	Equipment, sized in equipment reports
Installation labour and contractor margin	No	Part of construction services value
Expansion and rebuild materials in existing sites	Yes, USD 427.20 million in 2025	Same materials bought for halls added to live campuses

Out of scope in prose as well: copper electrical materials, mechanical and electrical equipment, installation labour, logistics and freight services, and land. In scope for every buyer group: hyperscale owners, colocation developers and enterprise and edge builders, including smaller regional contractors that buy through distributors.

Market Drivers: What Is Pushing Up Demand for Data Center Construction Materials?

Three forces lift the Data Center Construction Materials Supply Chain Market from USD 10.62 billion in 2025 to USD 13.38 billion in 2026: a record US build, tariff-driven steel prices and supplier pipelines that doubled in a year.

US Data Center Construction Hit a USD 96.46 Billion Annual Rate in September 2026

The US Census Bureau’s construction spending series shows private data center construction rising every month in 2026, from an annual rate of USD 56.21 billion in January to USD 96.46 billion in September (preliminary), now about twice the rate for general office buildings. Annual spending was USD 12.58 billion in 2022 and USD 49.74 billion in 2025. DC Market Insights puts the United States at USD 4.35 billion of shell-and-core materials in 2025, about 8.8% of that construction value.

Section 232 Steel Tariffs at 50% Reprice Every Frame Bought in the United States From June 2025

Proclamation 10947 raised the US tariff on steel and aluminum and their derivatives from 25% to 50% from 4 June 2025, and Proclamation 11021 applied it to the full customs value of derivative products from 6 April 2026. The producer price index (PPI) for steel mill products rose from 312.4 in December 2025 to 388.6 in September 2026 (US Bureau of Labor Statistics), and the index for bar joists and reinforcing bars rose 14% between May and September 2026. DC Market Insights lifts the structural steel price in its model by 8% for 2026.

Saint-Gobain Counts 1,085 Data Center Projects Under Specification in 32 Countries

Saint-Gobain reported on 30 July 2026 that its data center project pipeline had grown to 1,085 projects under specification in 32 countries, almost double a year earlier, with North America at 250 projects against 80. Kingspan reported that its Advnsys data infrastructure division entered 2026 with backlog up 24% and order intake in 2026 to date double the prior year (Kingspan Annual Report 2025). These pipelines support the jump to 15,000 MW of new IT capacity in 2026 in the DC Market Insights model.

Market Trends: How Are Data Center Builders Changing the Materials They Buy?

Hyperscale owners are shifting 2.00% of 2025 value into mass timber and pushing low-carbon concrete and steel into their specifications.

Microsoft and Meta Put Cross-Laminated Timber Into Data Center Shells

Microsoft said in October 2024 that its first hybrid cross-laminated timber (CLT) data centers in northern Virginia cut embodied carbon by 35% against conventional steel construction and 65% against typical precast concrete. Meta began piloting mass timber in 2025 at Aiken, South Carolina, and says it can reduce foundation concrete requirements by up to 50% (Meta, February 2026). DC Market Insights models Mass Timber Hybrid structures rising from USD 212.42 million in 2025 to USD 1.22 billion by 2035.

AI-Designed Low-Carbon Concrete Moves Into Hyperscale Specifications

An AI-optimised concrete mix developed by Meta and Amrize for Meta’s Rosemount, Minnesota data center cut the concrete carbon footprint by an estimated 35% and gained early strength 43% faster (Amrize). Amazon Web Services (AWS) reported 43 data centers built with lower-carbon concrete, steel or both, and higher-strength steel that saves 70 tons per two-storey building (Amazon, October 2023). DC Market Insights keeps these mixes inside the Ready-Mix Concrete and Rebar line, which grows 7.83% a year as slab and foundation volumes per MW fall.

Google Buys 91,000 Tonnes of Green Steel From Stegra

Google agreed in September 2026 to buy green steel certificates for up to 91,000 tonnes from Stegra’s first year of production and says its approach can cut embodied carbon in data center infrastructure by up to 40%. Owner-direct buying of this kind is why Owner-Direct Framework Agreements grow from USD 2.34 billion in 2025 to USD 8.27 billion by 2035 in the DC Market Insights model.

Market Challenges: What Could Slow Data Center Materials Supply?

Two constraints hold the Data Center Construction Materials Supply Chain Market below the pace of construction spending: metals cost volatility and new carbon rules on imported steel and cement.

Steel Price Swings of 107% Since 2020 Make Fixed-Price Shell Contracts Risky

The steel mill products PPI moved from 187.3 in January 2020 to a peak of 449.7 in December 2021, down to 266.5 in December 2024 and back up to 388.6 in September 2026 (US Bureau of Labor Statistics). For a 300 MW campus at 60 tonnes per MW, each 10% move in delivered steel price changes the materials bill by about USD 5.76 million (DC Market Insights estimate).

The EU Carbon Border Adjustment Mechanism Adds a Carbon Cost to Imported Steel and Cement From January 2026

The EU Carbon Border Adjustment Mechanism (CBAM) entered its definitive regime on 1 January 2026 for imports of cement, iron and steel and aluminium, with certificate prices tied to EU emissions trading auctions (European Commission). Importers of under 50 tonnes a year are exempt under Regulation (EU) 2025/2083, but data center frames run to thousands of tonnes, so European builders face higher costs on imported structural steel; DC Market Insights holds Europe at 7.98% a year, below the global rate.

Market Opportunities: Where Will Data Center Materials Suppliers Win the Most?

Prefabricated structures and site civil works for gigawatt campuses carry the largest new value, together worth USD 9.87 billion by 2035.

Prefabricated and Modular Structures Reach USD 5.59 billion by 2035

Clark Pacific says its AccelCore precast system delivers data centers 30-50% faster with floor capacity up to 600 pounds per square foot. DC Market Insights models Prefabricated and Modular Structures growing 14.17% a year from USD 1.49 billion in 2025, as owners trade higher material cost per MW for months saved on site.

Aggregates, Piles and Site Civil Materials for Gigawatt Campuses Reach USD 4.28 billion by 2035

Microsoft’s Fairwater campus in Mount Pleasant, Wisconsin needed 46.6 miles of deep foundation piles on a 315-acre site, and Martin Marietta shipped a record 67.1 million tons of aggregates in the third quarter of 2026 while naming data centers as a source of continued strength. DC Market Insights grows Aggregates and Site Civil Materials 9.74% a year, faster than the market, because gigawatt campuses need more piling, paving and stormwater works per MW.

Pricing: How Much Do Data Center Construction Materials Cost per Megawatt?

Shell-and-core materials cost about USD 849,500 per new MW in 2025, against USD 729,400 in 2020, as steel and concrete prices rose faster than building density (DC Market Insights estimate).

Year	Materials per new MW (USD)	Structural steel, fabricated and delivered (USD per tonne)	Ready-mix concrete (USD per cubic metre)
2020	729,400	1,984	128
2025	849,500	3,200	175
2030	836,100	3,668	194
2035	848,000	3,952	214

Public price anchors: the fabricated structural metal products PPI stood at 237.5 in January 2020 and 418.3 in September 2026 (+76%), the ready-mix concrete PPI rose from 286.5 to 402.8 (+41%) and the gypsum products PPI from 327.5 to 488.9 (+49%) over the same period (US Bureau of Labor Statistics). The 2030 and 2035 unit prices are DC Market Insights estimates with steel up 1.5% a year and concrete up 2% a year after 2026.

Standards and Regulation: Which Rules Change What Data Center Builders Buy?

Five rules shape the Data Center Construction Materials Supply Chain Market: two US tariff proclamations, the EU carbon border mechanism, the EU buildings directive and US federal low-carbon material limits.

DC Exclusive: The Shell-and-Core Materials Bill for One New Megawatt, 9 Line Items Totalling USD 849,500

This teardown is a DC Market Insights model estimate built on 13 inputs: nine material quantities and unit prices, the Fairwater steel and floor-area figures, the Abilene campus density and the US producer price indexes.

Line item	Quantity per MW	Unit price (USD)	USD per MW, 2025
Structural steel frame and metal deck	60 tonnes	3,200 per tonne	192,000
Ready-mix concrete	700 cubic metres	175 per cubic metre	122,500

Research Methodology: How DC Market Insights Sized the Data Center Construction Materials Supply Chain Market

DC Market Insights sized the Data Center Construction Materials Supply Chain Market bottom-up: new IT capacity of 12,000 MW in 2025, 22,000 MW in 2030 and 27,000 MW in 2035 × materials per MW by six material types (USD 849,500 in 2025), adjusted for price indexes and building density, plus USD 4,000 per installed MW-year for expansions inside live campuses (USD 427.20 million in 2025).

Three bound checks hold the estimate in place. Ceiling one: the USD 10.62 billion of 2025 is about 16% of the USD 65.60 billion DC Market Insights Data Center Construction Market. Ceiling two: the United States share of USD 4.35 billion is about 8.8% of the USD 49.74 billion of US data center construction put in place in 2025 (US Census Bureau). Floor: at Fairwater steel intensity and Abilene density, 12,000 MW × 33 tonnes × USD 3,200 per tonne gives about USD 1.27 billion of structural steel, below the USD 2.40 billion steel line. Segments, five regions and 12 countries are shares that sum to the total each year. See the DC Market Insights research methodology.
