Microsoft, Amazon, Google, and Meta are collectively spending over $200 billion on data center construction in 2025 and 2026. Every data center needs steel: structural frames, roof decking, equipment supports, cable trays, pipe for cooling systems, and plate for generator foundations. A single hyperscale data center campus uses 15,000 to 30,000 tons of steel. The United States currently has over 5,000 data centers, with hundreds more under construction or in planning.
The AI computing boom has accelerated data center construction to the point where it is now one of the largest steel-consuming construction categories in the country, behind only warehousing and logistics facilities.
What Data Centers Buy
Data center construction uses steel products that service centers commonly stock. Wide-flange beams and columns for structural frames: data centers require massive clear spans (60 to 100 feet) to accommodate server rows, which means heavy wide-flange sections. Steel roof deck (typically 20-gauge galvanized) for the roof system. Bar joists and joist girders for roof support. Structural tube (HSS sections) for secondary framing, platforms, and equipment supports. Plate for equipment pads, generator bases, and transformer foundations. Pipe for chilled water systems, which are the backbone of data center cooling.
The cooling system alone in a large data center can require 200 to 500 tons of carbon steel and stainless steel pipe in sizes from 2 inches to 24 inches. As data centers move toward liquid cooling for AI GPU clusters, the piping requirements are increasing significantly.
The Geographic Opportunity
Data center construction is concentrated in specific markets: Northern Virginia (the largest data center market in the world), Dallas-Fort Worth, Phoenix, Chicago, Atlanta, and increasingly central Ohio, central Indiana, and rural areas of the Southeast and Midwest where land and power are available.
If your service center is in or near one of these markets, you are sitting on a growth opportunity. The fabricators, mechanical contractors, and general contractors building data centers need local steel supply with fast turnaround. A mechanical contractor installing 400 tons of cooling pipe does not want to wait 8 weeks for a mill shipment when they discover they need 20 tons of 8-inch Schedule 40 pipe that was not on the original BOM.
How Data Center Buying Works
Data center steel is procured through the same channels as other commercial construction: general contractors award structural steel packages to fabricators, who source material from service centers and mills. Mechanical contractors source pipe and related products independently. Equipment manufacturers who build server racks, power distribution units, and cooling equipment buy sheet and tube for their products.
The unique aspect of data center procurement is the speed. These projects operate on compressed timelines because every month of delay is a month of lost computing revenue for the owner. A hyperscale data center generates $50 million to $100 million per year in revenue once operational. That urgency flows down to every supplier in the chain, including the steel distributor who needs to deliver on time, every time.
Positioning for This Market
Stock the products that data center construction consumes most: heavy structural shapes (W14 and W12 columns in weights above 100 lbs/ft), steel deck, and carbon steel pipe in the most common data center cooling sizes (6-inch, 8-inch, 10-inch, and 12-inch Schedule 40). Build relationships with the structural fabricators and mechanical contractors who work in your regional data center market. Understand their project timelines and material needs so you can stage inventory ahead of their requirements.
Data center construction is projected to grow at 25% to 35% annually through at least 2030, driven by AI computing demand that shows no signs of slowing. This is not a speculative market. The buildings are going up now, the steel is being ordered now, and the service centers that position for this demand will benefit for years.
