The data center boom is real, and it’s not a blip. The global data center market was worth around $416 billion in 2024 and is forecast to climb past $620 billion by 2029, with some analysts projecting it will reach roughly $1.1 trillion by 2035. Goldman Sachs expects global data center power demand to jump roughly 160% by 2030, driven largely by AI. Every one of those facilities needs a building to sit in, and more operators are looking at the same answer: pre-engineered steel.
Here’s why a steel building is a smart shell for a data center, and where it actually saves you time and money.
A data center is a race against the clock
Most of a data center’s cost isn’t the building. Industry breakdowns put electrical systems at roughly 40 to 45 percent of the total and mechanical systems at another 15 to 20 percent. The building shell and structure? Around 13 to 14 percent. A full build typically runs 18 to 30 months from concept to commissioning.
That math tells you where to find speed. You can’t rush the utility interconnect or the switchgear lead times, but you can compress the shell. A pre-engineered steel building is engineered and fabricated in a factory, then assembled on site. That gets the structure weathertight sooner, which gets your electrical and mechanical crews working inside sooner. In a project where every week of delay pushes revenue further out, the shell shouldn’t be the bottleneck.
Wide-open floors for the layout your equipment needs
Data halls don’t want interior columns in the middle of a server row. Red-iron steel framing carries the roof and wall loads at the perimeter, so you get clear-span, column-free floors. That means you lay out rows, hot and cold aisles, and power distribution the way your engineers designed them, not the way the structure forces you to. When you need to reconfigure later, there’s nothing structural in the way.
Room to grow without starting over
Capacity plans change fast in this business. The advantage of a pre-engineered steel building is that it’s designed to expand. You can extend the structure and add square footage down the road without tearing into what you already built. Start with the footprint you need now, and grow into the one you’ll need when the next contract lands.
Built to protect critical infrastructure
Steel is non-combustible, so the structure itself won’t ignite or feed a fire. It stands up to high winds and heavy snow, and it can be engineered for the seismic loads on your specific site. Add insulated metal panels, controlled ventilation, and provisions for cooling equipment and generators, and you’ve got an envelope built to keep expensive, mission-critical gear safe and climate-stable.
The bottom line
A steel building won’t cut your total data center budget in half — the power and cooling systems are where the real money goes. What it does is get you online faster, give you a floor plan that works, and let you scale when you need to. For a facility that has to protect critical infrastructure for decades, that’s a strong foundation.
