Security Cages for Warehouses: Wire Mesh Partitions & Enclosures Guide

Wire mesh security cages are one of the most versatile and cost-effective ways to protect inventory, equipment, and sensitive materials inside an existing building. Unlike solid walls, they maintain visibility, airflow, and sprinkler coverage while creating a physical barrier that deters theft and unauthorized access.

At Material Handling USA, we’ve designed and installed security enclosures for everything from pharmaceutical warehouses to law enforcement evidence rooms. This guide covers what you need to know to specify the right system.

What Are Wire Mesh Security Cages?

Security cages are modular enclosure systems built from welded wire mesh panels attached to steel posts. They can be configured as:

• Full enclosures — Four walls with a ceiling and lockable door(s)
• Partition walls — Divide open areas without full enclosure
• Tenant storage — Individual cages within a larger facility
• Machine guards — Surround robotic cells and automation equipment
• Server cages — Isolate colocation areas in data centers

Common Applications

Warehouse Inventory Protection

High-value inventory in distribution centers needs physical protection beyond cameras and alarms. Security cages create restricted access zones within your warehouse, allowing you to control who enters and when.

Data Center & Server Room Security

Colocation facilities use wire mesh cages to separate customer equipment. The open mesh design maintains the HVAC airflow that data centers need while providing physical security and meeting compliance requirements. See our security cage solutions.

Evidence & Property Rooms

Law enforcement agencies need secure, organized storage for evidence and inmate property. Wire mesh cages combined with mobile shelving systems maximize storage density while maintaining chain of custody. Learn more in our comprehensive evidence storage guide.

Tool Cribs & Maintenance Shops

Controlled access to expensive tools and spare parts reduces loss and improves accountability. Tool crib cages with Dutch doors or service windows let attendants issue tools without opening the entire enclosure.

Wire Mesh Specifications

Feature	Standard	Heavy-Duty	High-Security
Wire gauge	10 gauge	6 gauge	4 gauge
Mesh opening	2″ × 1″	2″ × 1″	1″ × 1″
Post size	2″ × 2″	3″ × 3″	3″ × 3″
Height options	8’–10′	8’–12′	8’–16′

Door & Access Options

• Hinged single door: Standard 3′ wide opening, most economical
• Hinged double door: 6’–8′ wide for forklift access
• Sliding door: Saves floor space where swing clearance is limited
• Dutch door: Upper and lower halves operate independently (ideal for tool cribs)
• Service window: Pass-through opening without a full door

All doors include integrated lock hardware. Options include keyed padlock hasps, cylinder locks, electronic card readers, and combination locks.

How to Specify a Security Cage

1. Measure the area: Width, depth, and available height
2. Identify the threat: Casual deterrence vs. forced entry protection
3. Determine access needs: How many doors, pedestrian vs. forklift access
4. Check building codes: Sprinkler coverage, emergency egress, ADA requirements
5. Select a finish: Powder coat (standard), galvanized (corrosion-resistant), or custom RAL colors

Frequently Asked Questions

How much do security cages cost?

Standard wire mesh cages cost $30–$60 per linear foot of wall, plus doors ($500–$2,000 each). A typical 10′ × 10′ × 8′ cage runs $2,500–$5,000 installed. Heavy-duty and high-security specifications cost 30–50% more.

Can security cages be relocated?

Yes. Modular panel-and-post systems bolt together and can be disassembled and reconfigured. This is a major advantage over drywall or chain-link, which are permanent and difficult to modify.

Do security cages need fire sprinkler modifications?

Wire mesh panels maintain sprinkler coverage and airflow, so in most cases no sprinkler modifications are needed. However, ceilings (tops) may require additional sprinkler heads inside the enclosure. Always consult your local fire marshal.
