Power distribution units (PDUs), generators, transformers and other critical infrastructure systems need to be protected, and metal enclosures are tasked with that role.
When we talk about the enclosures that house these vital systems, it's easy to focus on the basics: Will it fit the equipment? Will it hold up in the environment? But, for procurement pros sourcing enclosures, there is another layer to consider; Should I source a standard or custom solution.
We’re going to dive into how custom fabrication can make all the difference in performance, longevity in the field and total cost of ownership for critical infrastructure applications.
Custom enclosures play a key role across multiple industries, including:
Standard enclosures can be a convenient starting point, but they have limitations. Often, they require modifications after delivery to accommodate unique equipment layouts, cooling requirements or site constraints. That means additional time, costs, and potential headaches when trying to make a "one-size-fits-all" solution actually fit the application.
Downtime isn't an option for mission-critical applications—whether a PDU enclosure in a data center, a backup generator enclosure in a remote location, or an inverter enclosure for renewable energy. The enclosure itself needs to be engineered with the application in mind from day one.
Custom fabrication isn't just about making an enclosure that looks the part; it's about engineering a solution that aligns with the bigger picture. Here's why it matters:
1) Designed for Your Equipment, Not the Other Way Around
With a custom enclosure, you're not forcing your critical infrastructure into an enclosure that wasn't designed for it. Instead, you're getting a solution tailored to your footprint, cable management needs, access points and ventilation requirements, reducing the need for field modifications and ensuring a seamless installation.
2) Built for the Environment It Will Face
Critical infrastructure isn't always installed in climate-controlled warehouses. Some enclosures need to withstand harsh weather, extreme temperatures, salt spray or other industrial contaminants. Custom fabrication allows for material selection (e.g., aluminum for corrosion resistance, galvanized steel for durability) and protective coatings that extend the life of the enclosure and reduce maintenance costs.
3) Cooling and Airflow That Actually Work
Overheating is one of the biggest risks for power distribution and backup systems. A custom enclosure design ensures that cooling, whether through louvers, fans, heat exchangers or HVAC integration, is built into the structure rather than being an afterthought.
4) Compliance and Safety Without Compromise
Industries like telecommunications, energy, and utilities have strict regulatory requirements for enclosures. A custom approach means enclosures can be designed to meet NEMA, UL and other safety and performance standards from the start, avoiding costly compliance issues down the line.
5) Long-Term Cost Savings
Custom enclosures can reduce total costs over time. While an off-the-shelf enclosure might have a lower initial price tag, expenses add up when you factor in retrofits, additional cooling components, premature wear and tear and inefficiencies caused by a suboptimal fit. Custom solutions reduce these hidden costs by delivering exactly what's needed from day one.
As a procurement professional, your job isn't just about sourcing products; it's about sourcing solutions that support operational efficiency and long-term reliability. Working with a fabrication partner who understands critical infrastructure applications, engineering challenges and compliance requirements ensures that your enclosures aren't just protective shells but integral parts of a reliable, scalable system.
When your enclosures are purpose-built for their environment, your equipment runs better, maintenance costs drop, and unplanned downtime becomes less of a risk. That's why custom fabrication isn't just about a better enclosure—it's about a better long-term investment.
We specialize in custom metal enclosures for critical infrastructure applications. With decades of experience, we design and fabricate enclosures that protect, perform and push boundaries. Our expertise includes:
The next time you're evaluating new partners for UPS enclosures, transformer cabinets, outdoor telecom cabinets or other critical infrastructure applications, ask yourself: Will this enclosure work for us, or will we have to work around it?
Maysteel’s custom approach means you don't have to compromise. Because when it comes to critical infrastructure, there's no room for a "close enough" solution.
