The Backbone of Cabinet Design: Tubular Steel Solutions for Data Center Infrastructure
Inside every data center cabinet is a frame designed to do one thing exceptionally well: support and protect critical equipment without fail. For OEMs, that means every component, especially the steel tubing framework, must meet exacting standards. There's no room for error when uptime, airflow, and alignment are at stake.
At Alliance Tubular Products, we collaborate closely with some of the most forward-thinking manufacturers in the data center industry, supplying the structural tubing that forms the framework of their enclosures.
We manufacture direct-formed structural and mechanical steel tubing tailored for data center cabinet OEMs.
Why Tubing Quality Matters in Cabinet Manufacturing
While sheet metal forms the skin of most data center cabinets, it's the tubular frame that provides the rigid structure essential for stability, equipment load support, airflow optimization, and cable management. Poorly formed or inconsistent tubing can lead to frame misalignments, noisy operation, or even failure under load.
OEMs count on tight tolerances, consistent wall thickness, sharper corners, and precise dimensions, and that's precisely what our direct-formed tubing delivers.
What Is Direct-Formed Tubing?
Unlike mills that use a mother round tube and reshape it into square or rectangular profiles, Alliance Tubular Products uses a direct-forming process. We take slit coil steel from our sister company, Alliance Steel, and shape it directly into the required tube form from the first pass.
This approach offers measurable advantages:
- ✅ Tighter dimensional control
- ✅ Improved straightness and corner quality
- ✅ No round-to-square distortion
- ✅ Faster turnaround and less waste
These benefits are critical for data center cabinet manufacturers, where design precision is non-negotiable.
Common Types of Data Center Cabinets
Data center cabinets are typically classified into two main styles: open-frame racks and enclosed racks. Open-frame racks are ideal for maximizing airflow and offering easy access to equipment, while enclosed racks provide more control over security and environmental conditions. Additional formats include wall-mounted racks, which are great for compact or remote installations, and OCP (Open Compute Project) racks, which support high-density, scalable server deployments.
The most common standard is a 19-inch-wide rack, with heights measured in rack units (U), such as 24U, 42U, or 48U, and depths ranging from 24 to 48 inches. A 42U rack is very common.
Open-Frame Racks
- Advantages: Superior ventilation for cooling; simple access for service, upgrades, and cable management.
- Disadvantages: Lower physical security; often requires additional protection or restricted access areas.
Enclosed Racks
- Advantages: Lockable panels enhance physical security and help contain and manage airflow, thereby facilitating environmental control.
- Disadvantages: Potential for restricted airflow; less convenient access during equipment changes.

What's the Difference Between a Rack and a Cabinet in a Data Center?
When it comes to organizing and protecting equipment in a data center, two key terms often arise: racks and cabinets. While they may seem similar, there are key differences in how they function and where they're best used.
What Is a Data Center Rack?
A rack, often referred to as an open-frame rack, is a skeletal structure used to hold servers, switches, patch panels, and other networking equipment. With no side panels or doors, racks offer:
-
Unobstructed airflow for maximum cooling
-
Easy access for maintenance and cabling
-
Lower upfront cost
However, because everything is exposed, racks provide minimal protection against dust, physical contact, or unauthorized access. They're typically used in secure, climate-controlled environments or lab settings where airflow and accessibility take priority over security.
What Is a Data Center Cabinet?
A cabinet, or enclosed rack, is essentially a rack housed inside a protective shell. It includes side panels, front and rear doors (often lockable), and sometimes features built-in airflow control. Cabinets offer:
-
Increased security with lockable doors and panel protection
-
Better environmental control for cooling and dust management
-
Improved cable organization and equipment stability
Due to these features, cabinets are the preferred choice for enterprise data centers that require high security, structured airflow, and protection against environmental factors.
A data center cabinet, also known as an enclosed rack, provides a secure and protective enclosure for housing servers and network equipment. Unlike open racks, cabinets are fully enclosed with side panels and lockable front and rear doors. Many models also support integrated airflow management.
Key advantages of using cabinets include:
-
Enhanced physical security with locking mechanisms and enclosed sides
-
A controlled environment that supports cooling systems and limits dust exposure
-
Neater cable management and improved equipment organization
Due to their security and environmental benefits, cabinets are commonly used in enterprise data centers and colocation facilities, where equipment protection and efficient airflow are top priorities.
The four main types of data centers are classified based on their ownership, architecture, and the manner in which they serve end users. Each type supports different business needs, scalability options, and levels of control.
1. Enterprise Data Centers
These are privately owned and operated facilities used by a single organization, typically large corporations. They’re usually located on the company’s campus or a dedicated site.
-
Best for: Organizations needing complete control over infrastructure and security
-
Pros: Customization, direct oversight, tight integration with business systems
-
Cons: High capital and operating costs
2. Colocation Data Centers
In this model, businesses rent space, including power, cooling, and physical security, within a third-party facility. Customers bring and manage their servers and equipment.
-
Best for: Businesses needing reliability without building their data center
-
Pros: Shared infrastructure, cost efficiency, scalability
-
Cons: Limited control over facility operations
3. Managed Services Data Centers
These centers are operated by a third-party provider who manages both the infrastructure and the customer’s equipment. The customer outsources IT operations to the provider.
-
Best for: Companies that want to offload IT responsibilities
-
Pros: Expert support, reduced internal IT workload
-
Cons: Less customization, potential vendor lock-in
4. Cloud Data Centers
These are virtual data centers hosted by cloud providers like AWS, Microsoft Azure, or Google Cloud. The infrastructure is wholly owned and operated by the provider, and customers access services over the internet.
-
Best for: Organizations looking for flexibility, scalability, and rapid deployment
-
Pros: Pay-as-you-go, high scalability, no hardware investment
-
Cons: Less direct control, data residency concerns
