Why rack selection is a system-level decision
The wrong rack doesn’t just waste money — it causes cable chaos, thermal failures, weight overloads, and integration rework. Whether you’re deploying a data center row, a telecom cabinet, a battery bank, or a network closet, the rack is the structural backbone of your entire system.
Rule of thumb: Always spec rack depth, load rating, and cooling path before specifying brand or price.

| Height range | 18U – 47U | 6U – 42U | Open frame / 42U | Custom (floor to ceiling) |
| Load rating | 700–1500 kg | 100–500 kg | 300–800 kg | 1000–3000 kg+ |
| Cooling type | Front-to-back airflow | Passive / low-power | Forced air / HVAC | Ventilated / temp managed |
| Enclosure style | Closed cabinet | Open frame / wall mount | Open frame / enclosed | Enclosed / vented |
| Material | CRCA / SS | CRCA / Aluminum | CRCA / GI / SS316 | MS / SS304 (acid-proof) |
| Finish | Powder coat RAL 7021 | Powder coat / anodized | Hot-dip galvanized / PC | Epoxy / acid-resistant coat |

| Primary use | Data centers, IT rooms | Network closets, offices | 5G, BTS, telecom sites | UPS, solar, BESS storage |
Procurement tip: For outdoor or harsh environments, always specify IP rating + coating system — not just material grade.

Frequently asked questions
What is the difference between a server rack and a networking rack? +
Server racks are deeper (900–1200mm) to accommodate server chassis, with high load ratings and strong airflow management. Networking racks are shallower (450–800mm), lighter-duty, and optimized for patch panels, switches, and structured cabling.
What rack size (U) do I need for a small server room? +
For a small server room, 27U–36U is typically sufficient. Always add 25% growth buffer. A 42U rack future-proofs the installation and typically has the best cost-per-U ratio.
What is the standard rack width? +
The industry standard is 19 inches (482.6mm) internal mounting width. External cabinet width is typically 600mm or 800mm. Telecom uses ETSI standards which may differ.
What rack do I need for outdoor 5G / BTS equipment? +
Outdoor telecom deployments require IP55 minimum (IP66 recommended), hot-dip galvanized or SS316L frame, UV-resistant coating, forced-air ventilation or integrated HVAC, and cable entry glands with IP-rated seals.
How much weight can a standard rack hold? +
Networking racks: 100–500kg. Server racks: 700–1500kg. Battery racks: 1000–3000kg+. Always verify rail load rating independently from total frame capacity.
What coating is best for battery racks? +
Acid-resistant epoxy powder coat is standard. For VRLA batteries, an acid-proof coating on shelf surfaces and the base is mandatory. Stainless steel SS304 is used for high-corrosion environments.
What documents should come with my rack order? +
At minimum: inspection report, material traceability certificate, CoC (certificate of conformance), drawing revision reference, and packing / stacking photos for export orders.
Can you manufacture racks to custom dimensions? +
Yes — Eterna Global Solutions manufactures custom rack heights, depths, widths, and configurations for OEM, telecom, and BESS applications. Submit an RFQ with your requirements.
