Galvanized PVC Coated double twist hexagonal gabion stone cages
Hexagonal Gabion baskets and mattresses are available with a choice
of different wire coatings. Standard coatings are Hot Dip
Galvanised, Alu-Zinc (95% Zn + 5% Al) coated or PVC coated.
Alu-Zinc coated baskets are often mistaken for galvanised ones as
they look siar but can actually last up to 3-4 times longer under
siar exposure conditions. PVC coated cages on the other hand can
have a design life expectancy of up to 120 years, depending on
exposure conditions. PVC coated gabions should be considered for
longer service life requirements and for application near the sea,
river or locations where exposure to corrosive chemicals, acids and
salts is possible.
2x1x1m gabion box is the most common size, other common sizes are
1.5x1x1m, 1x1x1m, 2x1x0.5m, 1x1x1m etc. Larger sizes such as 3x1x1m
and 4x1x1m are also available to special order. Smaller landscaping
sizes such as 2×0.5×0.5m are also available.
Woven Mesh gabions are also available as Mattresses. Gabion
Mattresses are available 3x2m or 6x2m in plan and 0.17m, 0.23m 0.3m
or 0.5m thick. Mattresses are typically used for erosion control
and scour protection.
Advantages:
• Ability to deform without cracking allowing unpredictable
movement and settlement without loss of stability.
• Blends easily and harmoniously with the natural surroundings.
• Low cost alternative to concrete or masonry struc-tures.
• Very high resistance to natural forces due to better tensile
strength.
• Simple and speedy installation, making it cost effective.
• Easy and cheap repair to damaged cages.
Gabion box applications:
• Retaining wall structures
• River and canal training works
• Erosion and scour protection; roadway protection;
