Hot-Dip Galvanizing in the Data Center Industry

Is Hot-Dip Galvanizing a Suitable Corrosion Protection System for Data Centers?

As demand for cloud computing, artificial intelligence, digital storage, and high-speed connectivity continues to grow, data centers have become some of the most critical infrastructure assets in the modern economy. These facilities require reliable building systems and durable materials capable of performing for decades with minimal maintenance and risk of disruption.

Rapid growth in data center construction has demonstrated the value of hot-dip galvanized steel, a well-known and proven solution for other industrial buildings and infrastructure projects. Many of the industry's earliest large-scale facilities incorporated galvanized steel to achieve long-term corrosion protection while minimizing both cost and future maintenance requirements. Because data centers share many of the same design and performance requirements as other common industrial and infrastructure projects, engineers and specifiers frequently select hot-dip galvanizing as a familiar, proven solution for protecting steel. From structural steel and support framing to ladders, rooftop equipment supports, and miscellaneous steel fabrications, hot-dip galvanizing provides long-term durability and dependable performance while helping owners and contractors meet aggressive production and construction schedules.

One of the defining characteristics of today's data center construction market is speed. Owners, developers, and contractors are under increasing pressure to shorten design and construction schedules to bring facilities online as quickly as possible. Fortunately, many steel fabrications used in modern data centers are highly compatible with the hot-dip galvanizing process.

Many data center steel components are fabricated using straightforward and standardized designs that can be hot-dip galvanized easily with little design fabrication modifications required. For example, server enclosure designs only require the addition of small venting and drainage holes at the lowest/highest points of the enclosure when it is oriented for dipping. Some data center engineers have even worked with galvanizers during the design phase to ensure best practices are followed during design and fabrication. This undoubtedly reduces delays and improves coating quality.

Here are some commonly galvanized steel data center components:

• Structural Steel Framing Components
• Server Racks & Support Structures
• Server Enclosures
• Raised Access Floors/Platforms
• HVAC Support Structures
• Cable Management Systems (Cable Trays and Cable Baskets)
• Telecom Infrastructure
• Cooling Infrastructure
• Power Distribution Supports & Housings
• Walkways, Stairs, Ladders, & Handrails (grating improves airflow)

The tremendous amount of steel required for data center construction places significant demands on fabricators and contractors. Consequently, project teams often seek solutions that simplify fabrication and reduce potential bottlenecks. Efforts to simplify fabrication and ensure fabrications are well-suited for hot-dip galvanizing help streamline production while delivering corrosion protection before steel arrives on the jobsite. AGA provides free design guidance in accordance with ASTM A385/A385M in our publication Design of Products to be Hot-Dip Galvanized After Fabrication.

As data center designs continue to evolve, some owners and contractors are pursuing greater levels of prefabrication and modular construction. While larger preassembled fabrications can reduce field assembly requirements, some may require progressive dipping during the galvanizing process due to size constraints. Early coordination between the fabricator and galvanizer helps optimize fabrication design, galvanizing, transportation, and installation while maintaining project schedules.

It’s no surprise hot-dip galvanizing’s proven performance across similar infrastructure applications has carried over into the data center industry. Engineers routinely specify galvanized steel for exposed structural components, equipment supports, ladders, platforms, walkways, rooftop steel, utility infrastructure, and a wide range of ancillary systems in demanding environments.

The American Galvanizers Association provides a comprehensive library of technical resources to support engineers, architects, fabricators, contractors, and owners working on data center projects. Design guides, specification resources, performance data, inspection guidance, and life-cycle cost information are available to assist project teams in successfully implementing hot-dip galvanized steel.

By combining proven corrosion protection, construction efficiency, and decades of documented field performance, hot-dip galvanizing continues to be an effective, economical, and established choice for the rapidly growing data center industry.
