Gabion Spiral Wire

Hexagonal GABION WIRE DIAMETER AND COATING OPTIONS

Hexagonal Gabion baskets and mattresses are available with a choice of different wire coatings. Standard coatings are HDG (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 similar but can actually last up to 3-4 times longer under similar 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.PVC coated baskets are usually supplied with a grey PVC coating as standard but other colours are available to special order.

Standard wire diameter is 2.7mm, while 2.0mm and 2.4mm are available for certain mesh size combinations. Minimum thickness of PVC coating for woven gabions is 0.5mm.

Mesh Size Options    Options are also available with mesh size. The most common mesh size is 80mmx100mm for gabions and 60mmx80mm for mattresses. 100mmx120mm is also available to special order.

GABION SIZES    Baskets are available in range of sizes in half metre steps with the 2x1x1m gabion cage being 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. Gabion sizes are always denoted in Length x Width x Height.

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.
