Architectural gabion is welded mesh which is either mild steel coated with 300gsm of 10% aluminium and 90% zinc or 316L Stainless Steel. We stock a wide range of gabion products and accessories including C rings and gabion tools.


  • Rock Walls

    Gabion makes ideal garden walls for any landscaping project. They have the advantage of being easy to build and can look great. By using different rocks and materials a gabion wall can stand out. Useful to breakup areas of garden or park into separate areas. A low wall of 1m or less can be built to curve around a seating area for example. Also great for acoustic walls by using sound absorption materials within the wall with rocks on the outsides.

  • Retaining Walls

    Gabion has traditionally been used for retaining walls due to its low cost compared to conventional methods. They can be built as either mass gravity walls (relying on the weight of rock to retain the earth) or as mechanically stabilized walls (which use geogrids or earth anchors to hold the wall in place).

  • Cladding and Columns

    Architectural gabions are perfect for cladding an otherwise ugly concrete facade or column. They can be built to a depth of only 200mm. It is often used in front of woven (hex mesh) gabion which is cheap but unattractive. By building an architectural gabion facade in front of a saggy woven wall a designer can achieve both cost savings and a fantastic looking building or wall.

ASTM 974-97 is the only standard for welded gabion. The standard states that the minimum requirement for a gabion weld mesh is that if it is a mild steel it must have a minimum coating of 275 gsm (4mm wire). It should be noted that standard galvanized weld mesh DOES NOT meet this standard and is usually closer to 60 grams or less of coating. In an ideal situation a standard galvanized mesh can still last 10-25 years but is severely affected in any aggressive environment.

AL-TEN gabion wall

AL-TEN™ (mild steel mesh) Gabion

SHOP Gabion

Manufactured in mild steel to a minimum wire coating of 290 grams per m2 which is Aluminium 10% and Zinc 90%. The mesh is manufactured in Australia and exceeds gabion specification ASTM 974-97.

AL-TEN has a high Aluminium content (10%) coating which over time turns the mesh into a darkish grey colour. This has the benefit of absorbing light rather than reflecting it. Especially apparent when viewing a wall from an angle, the rock is more visible and the mesh less so. Using a highly reflective finish such as galvanized, stainless steel or PVC results in the mesh being more visible to the eye when viewing at angles.

Aperture: The aperture is the distance from the centre of one wire to the centre of the next both horizontally and vertically.

We are currently producing as standard products both 4mm and 5mm mesh in 75mm x 75mm aperture and 4mm in 100mm x 50mm aperture.

Custom manufacturing to different aperture sizes, for example 50mm x 50mm, 100mm x 100mm in both 4mm and 5mm diameter wire.

Standard Aperture Sizes

75mm x 75mm aperture, the most common size. When calculating cage sizes take into account that all lengths, widths and heights will be in increments of 75mm. Overall it is easier working with a square aperture than a rectangular one, however a rectangular aperture can have a stunning look.

100mm x 50mm aperture. When calculating cage sizes take into account that lengths, widths will be usually be in increments of 100mm and heights 50mm. This is based upon it being more common for 100mm in the horizontal plane.

Sometimes it is desirable to place the 100mm vertically (eg if a high wall this may be done to deter climbing).

Estimated Lifespan

Although difficult to predict as lifespan of all steels is largely dependent upon the environment. Generally you can expect 20 years life for galvanized wire, and 2-5 times longer life span for Galfan, AL-TEN™, PVC coated and stainless steel 316L.

The mesh life is dependent upon no damage to the coating during installation or during the lifetime of the wall. Because the wire is a coated mild steel any damage to the mesh which removes the Zinc/ Aluminium coating will eventually corrode. If upon inspection damage to the coating is seen or corrosion has occurred it needs to be rectified.

Other considerations when determining lifespan is soil PH levels if the product is placed directly on the earth. A geotextile fabric such as Syntex nonwoven 145gsm may be used as a separation layer. Some rock such as limestone has a high PH (alkaline) which may have a detrimental effect on the mesh.

Rock cleaning or other chemicals including acids and caustic solutions which come into contact with a Galfan, Galvanized, Stainless Steel mesh may have a detrimental effect to metal surfaces and may cause premature corrosion and breakdown at areas of contact. It is recommended to not use any chemicals and to wash immediately with water should contact occur. If exposure to corrosive type chemicals to Zinc and Aluminium is expected alternative systems should be considered following analysis of potential problems. Once corrosion has occurred it may be necessary to apply a rust remover and to then apply either a cold galv or zinc/aluminium paint to affected areas.

Corrosivity Table

Expected lifetime for the different coating classes and different corrosivity categories is shown in the table. Corrosion is a complex issue. Due to the many variables including prevailing wind direction, type and concentration of corrosive contaminants, the amount of sea spray present and the relative periods of moisture or condensation and dryness, only an estimate of expected life can be made in regards to the wire life expectancy. The corrosivity classes are based upon the standard EN ISO 9223.

The table is based upon test data of the wire during simulated laboratory testing.

C1: Very Low (Internal buildings with clean atmospheres) 100 years +
C2: Low (Low level of pollution, mostly rural areas) 100 years +
C3: Medium (Urban and industrial atmospheres, moderate sulphur dioxide pollution, coastal areas with with low salinity) 93 years
C4: High (Industrial areas and coastal areas with moderate salinity) 47 years
C5: Very High (Industrial areas with high humidity and aggressive atmosphere, coastal and offshore areas with high salinity) 25 years
CX: Extreme (Extreme industrial areas, coastal and offshore areas with occasional contact with salt spray) < 10 years

Anticipated lifetime years until 5% dark brown rust

Stainless Steel 316L Gabion

Manufactured in rust resistant 316L Stainless Steel and used where salt water is likely to come into contact with the gabion or where customers prefer the look of stainless steel.

There are 3 standard grades of common stainless steels. 302, 304, 316. Our 316 is manufactured in the more resistant 316L grade. The L designates it is a low carbon stainless and is considered to be more suited as a marine grade steel. The advantage with 316L is that the welds are more resistant to corrosion. But it can still corrode. To determine the rate of corrosion is almost impossible due to differential rates of ionization, the effect of waves, drying and wetting (tidal action), etc. Some projects in the Gulf of Mexico were installed in the early 90’s and still appear in pristine condition, while others in different parts of the world have deteriorated.

The disadvantage is that it has a tendency to discolour from the effects of salt and some chemicals. It can appear as though it has oxidized, even if it hasn’t.

PVC Coated Weld Mesh Gabion

USA made PVC coated gabion which incorporates a steel wire which is hot dipped galvanized followed by a coating of primer and then a fuse bonded, powder coated PVC. This is the maximum protection for a gabion and is superior to all others in severe environments where the gabion is in contact with salt water. This type of gabion is supplied in roll form.

Fuse bonded PVC powder coating of welded mesh gabions is bonded uniformly to mesh after welding to form a super skin. This prevents corrosive liquids from attacking the galvanized core wire – even in salt water. The fuse-bonding coating process eliminates residual stresses in the coating inherent in the extrusion process used by other gabion types so the PVC retains its UV protection and prevents infiltration by water or other liquids and thus prevents any subsequent migration of those liquids along the core wire. The single wire strands of welded mesh cannot move at the joint so there is no internal wire abrasion to damage the coating.

PVC coated mesh is supplied in rolls of 0.99m wide x 91.44 length.
