Box gabions consist of rectangular units, fabricated from
double-twist, hexagonal mesh of soft annealed, heavily zinc coated
wire.
Filled with stone, gabions become large, flexible and permeable elements from which a
broad range of structures can be built (retaining walls, river bank protections, weirs,
etc.).
Gabions are divided into cells with diaphragms, whose function is to reinforce the
structure. The mesh (except for the diaphragms) is reinforced on all edges with wires of a
larger diameter to strengthen the gabions and facilitate the assembly and installation.
Gabions can also be manufactured with wire mesh coated with a continuous
PVC (polyvinyl chloride) sleeve. This provides protection against
corrosion making them suitable for use in marine or polluted environments. Gabions are also
available in Galmac wire.
