Hot-dipped galvanized gabion basket / galfan coated hexagonal mesh gabions
Product Description:
Gabions are rectangular cages made of hexagonal double-twist wire mesh filled with appropriately sized rock, the Gabions are sub-divided into cells by inserting diaphragms which are mesh panels with the same characteristics as the external sides, spaced 1m from each other to give the structure strength and facilitate it's speedy construction.
Before woven, the galvanized wire can be coated with a special PVC (polyvinyl chloride) coating 0.5mm thick. This additional coating gives full protection from corrosion in marine or heavily polluted environments.
· Double twist to avoid unraveling
· Reinforcing wires woven into corners to reinforce critical points
· A diaphragm securely attached at the base that will prevent the shifting of some and reinforce the gabion.

Advantages of Defensive barriers:
1. FLEXIBLE
Superior to rigid type structures. The hexagonal mesh construction permits natural adjustment to varying conditions of earth settlement without causing fracture or collapse of the structure.
2. DURABLE
Gaps between the stones silt up naturally as time passes. Silting supports the growth of grass and plants which serve as a bonding agent for the stone.
3. PERMEABLE
A Gabion structure allows water to pass through, water pressure cannot build up behind it and the structure is continuously drained.
4. STRONG
The flexibility of the Gabion structure provides the inherent strength to withstand and dissipate pressures exerted by water and earth masses.
5. ECONOMICAL
Filling materials are usually found on or near the site. No structural maintenance is needed and foundation work is usually unnecessary.
6. NATURAL APPEARANCE
Natural stone makes the structure aesthetically pleasing especially when subsequent vegetation growth takes place.
Galfan coated gabion box applications:
Gabions are used in many situations including the stabilization of earth movement and erosion, river control, reservoirs, canal refurbishment, landscaping and retaining walls. They can be manufactured in welded mesh or woven wire.
