Heavy duty gabion mattress for bridge scour: Preventing Bridge Scour and Slope Erosion
Product Overview
A critical infrastructure project along the highway corridor in Trentino, Italy, faced severe vulnerability during
the annual winter thaw.
The Challenge: Infrastructure Vulnerability
Fast melting mountain snow triggered fierce torrents. Rapid floods scoured bridge piers and destroyed nearby drainage works. Conventional rock riprap washed away under 4.2 m/s flow, exposing the bridge foundation and threatening key transport routes.
Why Our Gabion Mats Stood Out
They selected our high-performance erosion control system, which offered distinct technical advantages:
1.Structural Integrity
Double-twisted hexagonal mesh stays intact even when individual wires snap.
2.Superior Durability
Galfan alloy gabions deliver a service lifespan exceeding 50 years.
3.Flexibility & Hydraulic Efficiency
Flexible structure fits riverbeds, dispersing water force better than rigid concrete.
Project Solution Matrix
·Product Applied: Galfan coated gabion mattresses (0.3m thickness, 2x1m cell layout).
·Installation Area: 4,500 square meters protecting the bridge apron, pier bases, and adjacent drainage outlets.
·Infill Material: Locally sourced 100-150mm hard river stones.
Because the mattresses arrive flat-packed and pre-assembled, workers simply unfolded them on-site, secured them with pneumatic lacing tools, and filled them
using standard mechanical excavators.
This streamlined process eliminated the need for complex formwork,specialized labor, or concrete curing times. The contractor reduced the total installation schedule by 35** and saved significant labor costs compared to poured-concrete options.
Long-Term Results
Six years after installation, the bridge and drainage system stay stable.
Sediment and plants integrate gabions into nature.
The gabion system resisted three severe floods with nodisplacement, securing highway traffic.

Frequently Asked Questions
We can suggest experienced installation partners for barbed wire and razor wire projects in various regions. Technical guidance from our engineers may also be available when required.
Production usually takes 3–5 weeks after order confirmation, depending on barbed wire specifications and order volume. Flexible scheduling may be available for urgent project timelines.
Yes, standard galvanized barbed wire offers reliable corrosion resistance for 8–12 years under normal outdoor conditions. Additional coating options are available for more demanding environments.
Our standard razor wire is produced in 450–980 mm coil diameters with wire thickness ranging from 2.3–2.8 mm. Custom specifications can also be arranged to suit different security fencing requirements.
