Metal Gabions: Complete Technical Guide
Introduction
Metal gabions represent one of the most versatile and effective solutions in civil and environmental engineering works. These seemingly simple but technically sophisticated structures have revolutionized the way problems related to soil containment, hydraulic protection, and landscape integration are addressed.
For professionals in the field-engineers, architects, construction companies, and public administrations-a thorough understanding of the characteristics and potential of metal gabions is essential for designing effective, sustainable, and cost-effective interventions.
Technical Definition: What are Metal Gabions
Metal gabions are modular elements consisting of parallelepiped containers made of double-twisted wire mesh, filled with stone material of appropriate size. The term “gabion” is derived from the Latin “cavea” (cage), highlighting the containing nature of these structures.
From a technical point of view, a metal gabion is characterized by:
- Containing structure: made of galvanized or coated wire mesh
- Backfill material: stones of specific sizes and characteristics
- Assembly system: locking and reinforcing elements that ensure structural integrity
Fundamental Technical Features
- Structural Flexibility Metal gabions possess a high capacity to adapt to ground deformation without losing their functionality. This characteristic makes them particularly suitable in complex geological settings or those subject to settlement.
- Permeability The open structure provides excellent drainage capacity, which is essential for managing hydrostatic pressures and preventing instability.
- Mechanical Strength Despite their apparent simplicity of construction, metal gabions offer high mechanical performance, with the ability to withstand significant loads and dynamic stresses.
- Durability Modern protective treatments (galvanizing, Galfan, polymer coatings) ensure a service life of the work in excess of 50 years under standard environmental conditions.

FAQ - Frequently Asked Questions about Metal Gabions
What is the main difference between metal gabions and concrete walls?
Metal gabions are flexible, draining structures that adapt to soil settlements, whereas concrete walls are rigid. Gabions have 30-40% lower costs and 50% shorter installation time.
How long do metal gabions last?
With modern protective treatments (galvanizing + PVC), metal gabions guarantee a service life of more than 50 years under standard environmental conditions, up to 120 years under optimal conditions.
Do you need special foundations for metal gabions?
No, generally, preparation of the laying surface with compacted granular material is sufficient, significantly reducing costs compared with reinforced concrete foundations.
