Expanded Metal Applications

Expanded Metal Fencing & Security

A practical guide to how expanded metal mesh is used for perimeter fencing, gates, security screens and architectural infill.

Introduction

What Is Expanded Metal Fencing?

Expanded metal fencing starts as a solid metal sheet. It is slit and stretched into a continuous mesh, creating diamond or decorative openings without separate wires or welded intersections.

Its one-piece structure combines rigidity with visibility and airflow - ideal when a boundary needs protection without becoming a solid wall.

One-piece integrity
Connected strands remain stable inside the frame.
Clear sightlines
Openings retain visibility through the boundary.
Natural airflow
The mesh allows light and ventilation to pass.

Visual Examples

From perimeter boundaries to gates, railings and framed screens, the same mesh principle can support very different architectural and security requirements.

Key Characteristics

Why Expanded Metal Works for Fencing

  • 01Continuous constructionStable interconnected strands with no welded intersections.
  • 02Open visibilitySupports surveillance, daylight and visual connection.
  • 03Natural ventilationAllows airflow around equipment and service areas.
  • 04Flexible appearancePattern, direction, framing and color can be adapted.

Common Uses

Where Security Mesh Is Used

  • Perimeter fencingIndustrial sites, utilities and public facilities.
  • Gates and access pointsSliding, swing and controlled entrances.
  • Railings and balustradesBalconies, stairs, walkways and platforms.
  • Equipment enclosuresVentilated protection for machinery and services.

Selection Guide

Materials, Finishes and System Design

Choose the mesh as part of the complete fence system - not as an isolated panel.

Carbon Steel

Strong and economical; commonly galvanized or powder coated for outdoor use.

Stainless Steel

Suitable where corrosion resistance and a clean metallic finish matter.

Aluminum

Lightweight and well suited to architectural screens and railing infill.

Confirm Before Installation

  • Opening size and visibility
  • Mesh direction and frame spacing
  • Edge treatment and fixings
  • Exposure and surface coating
  • Local wind, safety and security rules

Installation

Fit and Support the Panel Correctly

  • Support panels evenly to limit movement.
  • Protect cut edges after fabrication.
  • Use compatible frames and fasteners.

Maintenance

Keep the Finish in Good Condition

  • Remove dirt and nearby vegetation.
  • Check loose fixings and coating damage.
  • Inspect coastal installations more often.
