How to Choose the Right Machine Guarding Fence for Robotic Cells and Automation Lines

Selecting the right safety fencing for automation, robotics, and industrial manufacturing projects.

 

Introduction

As industrial automation continues to transform manufacturing, machine guarding has become more than a compliance requirement—it’s an essential part of protecting employees, maximizing productivity, and ensuring efficient workflows. Whether you’re building a new robotic cell or upgrading an existing automation line, selecting the right machine guarding fence can significantly impact safety, maintenance, and long-term operating costs.This guide will help you understand the key factors to consider before making your decision.


1. How to Choose the Right Fence Height

Selecting the correct fence height is essential for ensuring operator safety while maintaining easy access for maintenance and production.

The required height depends on several factors, including the robot’s reach, operating speed, potential hazards, and the minimum safety distance specified by applicable standards such as EN ISO 13857, EN ISO 14120, and CSA Z432-16.

Common Fence Heights

Fence Height Recommended Applications
1000 mm Ideal for low-risk areas, equipment separation, AGV/AMR traffic lanes, and perimeter zoning where full-height protection is not required.
2000 mm The most popular choice for robotic cells, CNC machines, automated production lines, palletizing systems, and other applications requiring full personnel protection.
Custom Height Designed for applications with unique safety requirements, oversized equipment, or project-specific layouts. Available upon request.


2. Wire Mesh or Polycarbonate Panels?

One of the most common questions is whether to choose wire mesh panels or polycarbonate panels.

Wire Mesh Panels

Wire mesh is the most widely used solution for industrial machine guarding because it offers:

  • Excellent ventilation
  • Clear visibility for operators
  • Lower overall cost
  • Lightweight modular construction
  • Easy maintenance

It is ideal for:

  • Robot cells
  • Conveyor systems
  • Assembly lines
  • General automation equipment

Polycarbonate Panels

Polycarbonate panels provide additional protection where operators need shielding from process hazards.

Recommended applications include:

  • Laser processing equipment
  • Welding cells with sparks and spatter
  • High-speed machining
  • Dust or debris containment
  • Applications requiring stronger visual barriers

Although polycarbonate systems generally cost more, they improve operator protection in demanding environments.

Many factories also combine wire mesh panels with polycarbonate panels within the same project to achieve the best balance between visibility and protection.


3. Why Modular Design Matters

Modern factories are constantly evolving.

Production lines are relocated, robotic stations are upgraded, and new equipment is added every year.

A modular machine guarding system allows manufacturers to adapt quickly without replacing the entire fence.

Key benefits include:

  • Faster installation
  • Easier expansion
  • Lower labor costs
  • Simple replacement of damaged panels
  • Flexible layout modifications

Compared with traditional welded structures, modular guarding systems can reduce installation time by up to 30%, minimizing production downtime during installation.


4. Selecting the Right Door Configuration

Safe access is just as important as the fence itself.

The best door type depends on available space and production workflow.

Swing Doors

Suitable for:

  • Standard operator entrances
  • Maintenance access
  • Most automation cells

Sliding Doors

Recommended when floor space is limited.

Ideal for:

  • Robot loading stations
  • Narrow aisles
  • High-frequency access areas

Folding Doors

Recommended when maximum opening width is required while saving space.

Ideal for:

  • Large robotic cells
  • Wide maintenance access
  • Material loading and unloading areas
  • Production lines with limited swing space

5. Integrating Safety Interlocks

A machine guarding fence becomes significantly more effective when integrated with safety interlocks.

Safety interlocks communicate directly with the machine control system.

When a gate is opened:

  • Machine motion stops automatically.
  • Hazardous movement is prevented.
  • Operators can safely enter the protected area.

This integration helps manufacturers comply with international safety standards while reducing the risk of accidental entry into hazardous zones.

Modern safety systems can also support:

  • RFID safety switches
  • Electromagnetic safety locks
  • Emergency stop buttons
  • Access control systems

6. Consider Long-Term Ownership Costs

The purchase price is only part of the overall investment.

Engineers should also evaluate:

  • Installation time
  • Future expansion capability
  • Maintenance requirements
  • Spare parts availability
  • Technical support
  • Product durability

A well-designed machine guarding system often delivers lower total project costs over its entire service life.
