Why the AI Data Center and Server Industry Needs More Advanced Sheet Metal Solutions
Since OpenAI released GPT in 2018 and AI adoption began accelerating rapidly around 2020, global demand for computing power has surged. Power consumption for a single GPU server has already exceeded 1400W. In applications defined by this level of power density and system integration, conventional sheet metal fabrication methods are no longer enough.
Server enclosures, cabinets, power supply housings, and thermal management components form the physical foundation of AI infrastructure. Their structural integrity, cooling performance, and electromagnetic shielding directly affect the stability and reliability of the entire computing cluster. A mature sheet metal solution for data center applications must go far beyond basic fabrication. It needs to address thermal management, EMC performance, and serviceability at the design stage, while also relying on precision manufacturing to ensure every detail can withstand demanding operating conditions and protect high-value server components.
Common Problems in AI Data Center and Server Equipment Manufacturing
| Issue Type | Typical Problem | Potential Impact |
|---|---|---|
| Thermal design flaws | Poor rack airflow design creates localized hot spots; vent locations do not align with actual heat sources | Overheating and thermal throttling, with performance dropping by more than 30%; reduced hardware lifespan |
| Insufficient electromagnetic shielding | Poor shielding performance at sheet metal joints; improper grounding design | Signal interference, higher data transmission error rates, and failure to meet EMC certification requirements |
| Inadequate structural strength | Equipment weight increases with higher power density, but the support structure is not reinforced accordingly | Long-term deformation, leading to poor contact, misalignment, or equipment damage |
| Improper surface treatment | Inadequate corrosion protection; uneven conductive coating | Failure in salt spray testing and unstable electrical connections |
| Uncontrolled dimensional tolerances | Tolerance stack-up makes assembly difficult and reduces part interchangeability | Lower assembly efficiency, higher rework rates, and delays in delivery |
| Incorrect material selection | Material does not match the operating environment, such as using standard carbon steel in high-humidity conditions | Premature corrosion and failure, resulting in higher maintenance costs |

Our Manufacturing Capabilities
SR MFG offers a complete and advanced sheet metal fabrication process chain, with every stage carefully optimized to meet the demanding standards of the AI data center and server industry.
Metal Bending
For rack and frame products used in AI data centers, we apply multi-stage bending processes to ensure the verticality and parallelism of the structure meet installation requirements. For high-strength server cabinets in particular, we have developed specialized bending methods that reduce springback and deformation by optimizing the bending sequence.
Metal Stamping
For standardized components produced at high volume, we use precision stamping to improve efficiency while maintaining consistent quality across every part. Our stamping dies are designed and built by a dedicated team to ensure repeatability and uniformity, which is especially valuable for large-scale data center deployments.
Welding
Welding has a direct impact on both structural strength and finished appearance. For the frame structures of AI server cabinets, we use robotic welding to ensure consistent weld quality and uniform strength. For parts with higher cosmetic requirements, we use laser welding to achieve clean, low-visibility seams.
Surface Finishing
Surface finishing affects more than appearance alone; it also plays a critical role in corrosion resistance and electromagnetic shielding performance. We provide complete finishing solutions tailored to the specific demands of data center environments, including specialized anti-corrosion coating systems capable of passing more than 1,000 hours of salt spray testing.
Assembly
Assembly also requires disciplined process control to ensure that every step follows clearly defined operating procedures and inspection standards. For complex cabinet systems, we use a modular assembly approach, assembling individual sections separately before completing final system integration.

Material Selection Guide
Choosing the right material involves more than comparing cost and performance alone. It is also important to consider manufacturability, lead time, and long-term maintenance costs. Our engineering team can recommend the most suitable material based on your specific application requirements.
| Material Type | Thickness Range | Key Characteristics | Recommended Applications | Cost Level |
|---|---|---|---|---|
| Cold-rolled steel (SPCC) | 0.8–3.0 mm | High strength, low cost, and good formability, though corrosion resistance is relatively limited | Standard server cabinets and general frame structures | Low |
| Galvanized steel (SGCC) | 0.8–2.5 mm | Good corrosion resistance and suitable for indoor use without additional surface finishing | PDU enclosures, network equipment chassis, and internal structural parts | Medium |
| Stainless steel (SUS304) | 0.5–3.0 mm | Excellent corrosion resistance and high strength, but higher in cost and more difficult to process | Equipment used in high-humidity environments, laboratory systems, and medical-related applications | High |
| Aluminum alloy (5052/6061) | 1.0–5.0 mm | Lightweight, thermally conductive, and electrically conductive, though lower in strength than steel | Heat sinks, high-power equipment housings, and weight-sensitive applications | Medium to high |
| Electro-galvanized steel (SECC) | 0.8–2.5 mm | Well-balanced overall performance, moderate cost, and suitable for volume production | Standardized server components and large production runs | Medium |
| Aluminum-magnesium alloy (5083) | 1.0–6.0 mm | High-strength aluminum alloy with strong corrosion resistance, suitable for marine or coastal environments | Data center equipment in harsh environments and coastal installations | High |

Quality Control Plan
We develop inspection plans based on the specific characteristics of each product. These typically include checks on incoming material thickness and surface condition, along with first-article dimensional inspection. For critical structural components, we can also carry out focused inspections covering flatness, perpendicularity, dimensional tolerances, and other key requirements, so that potential issues are identified and resolved before shipment.
For production programs that require a higher level of consistency, we recommend defining critical dimensions, cosmetic standards, and assembly inspection criteria during the prototyping stage. Aligning on these requirements early can significantly reduce disputes during mass production and improve overall delivery stability.
Lead Time and Cost
- Prototype production (1–10 pieces): 7–10 days, including process validation and first-article inspection
- Low-volume production (10–100 pieces): 10–15 days, including tooling preparation and production line setup
- Mid-volume production (100–1,000 pieces): 15–20 days, with full batch production and stricter quality control
- High-volume production (1,000+ pieces): 20–30 days, with partial shipments available to help reduce inventory and cash flow pressure on the customer
Note: Lead times are calculated from the date the order and drawings are officially confirmed. They do not include time required for design revisions or customer approval. If materials need to be specially sourced, or if the product involves a complex structure or special processing requirements, the lead time may be extended.
We understand that urgent production needs sometimes arise. To support these situations, we offer expedited manufacturing options:
- Expedited service: Shortens the standard lead time by 30%–50%, with an additional charge of 10%–20% of the total order value
- Priority rush service: Prototype or low-volume orders delivered within 7 days, with an additional charge of 20%–30% of the total order value
Note: Expedited service requires special scheduling across both production and supply chain operations, which is why additional costs apply. Whenever possible, we recommend planning ahead to avoid unnecessary rush charges.
