Iso 9001 Galfan Coastal Defence Woven Mesh Gabions / Welded Gabion Wall

Product Specification

ISO 9001 Galfan Coastal Defence Woven Mesh Gabions

Products Description: 

Woven Gabions are regularly used in industrial and enviromental applications providing a cost-effective alternative where the visual impact of the gabion is less important.  

But the woven gabions give the same efficient drainage and flexibility as weldmesh gabions and installation can be carried out quickly and easily by unskilled labors  without sprcial tools.

The woven gabion units are manufactured with a double twist woven hexagonal wire mesh with a core of 2.7mm and jointed with 2.2mm tying wire which included in the cost along with the quotes.  You can choose from Galvanized, galfan or PVC coated wire to suit the relevant application and required lifespan.

Woven Gabion box advantages:

Double Twisted Hexagonal Mesh Gabions & es have been used for channel linings, river training, soil retention, slope stabilization, and other applications successfully throughout the world for over 100 years. Double Twisted Mesh Gabions & es offer many advantages over other types of construction materials. Some of the advantages offered by double twisted mesh gabions & es are flexibility, durability, strength, permeability, ecology, reliability, longevity, low cost, and an aesthetic appearance.

• Flexibility

One of the most important advantages of double twisted mesh gabions & es is their flexibility both for the individual unit and the overall gabion or structure. The Double Twisted Hexagonal Mesh construction of the units permits it to tolerate differential settlement without failure. This property is especially important when a structure is on unstable soil conditions or in areas where scour from wave action or currents can undermine the toe of the structure and cause structural settlement.

• Durability

Gabions & es built from high strength double twisted hexagonal mesh filled with natural hard durable stone and connected together to create a monolithic mass structure capable of undergoing structural movement without any loss of structural integrity creating a highly durable structure.

• Strength

Double Twisted Hexagonal Mesh Gabions & es possess the strength and flexibility to withstand forces generated by water and earth masses. The most important and relevant strength characteristics pertaining to gabion and design standards are the mesh punch strength, the mesh tensile strength, the pull apart resistance strength of the mesh, and the corrosion resistance of the mesh. The strength values of the double twisted mesh are located within the individual product specifications for each product and are represented in ASTM A975-97.

• Permeability

Gabions & es create structures that are naturally free draining. Hydrostatic heads do not develop behind gabion and structures. Drainage is accomplished by gravity and by evaporation as the porous structure permits an active air circulation through it. Moreover, as soil is deposited and plant growth invades the structure, transpiration further assist in removing moisture from the soil being protected.

• Ecology

Gabions & es offer an environmentally sensitive solution to soil retention slope stabilization. Gabion and structures utilize natural stone for their stability and strength. Constructed of natural stone fill the gabions are naturally porous allowing interaction between the land and the water table. Soil will generally be deposited in the small voids of the stone fill material during drainage and draw down and will promote vegetated growth inundating the structure. Over time in some applications the structure can become so inundated with vegetation as to no longer be visible. Vegetation, plant and tree growth can be implemented at the time of construction utilizing several methods to ensure vegetation occurs immediately.

• Reliability

The overall strength characteristics offered by the double twisted hexagonal mesh gabion and listed above and the long successful history of the material usage world wide ensures that the double twisted mesh gabions and es will perform as designed.

• Low Construction Cost

Gabions & installations are very cost effective. Gabions & es are easy to construct requiring limited equipment, unskilled labor, minimal foundation preparation, no drainage provisions, and low cost stone fill generally provided by a local stone or rock supplier. Gabion & structures require very little if any maintenance and if designed and built properly can be a permanent structure.
