Whether you’re looking for an erosion control solution at your project or want to use them as an architectural element inside or outside a building, gabions have a lot to offer. They not only prevent soil erosion on coast lines but are also great at preventing landslides and washouts. You can use different types of gabion baskets to provide stream-bank stabilization or reinforce roadside slope erosion problems. You can also use them in constructing decorative and sound dampening fences for residential and commercial applications as well as use larger baskets for security and fire protection in a variety of applications including government and military.
Gabions easily blend with the local environment due to the ability to use locally sourced fill material. Because they can drain water easily, they are highly stable as a retaining structure. Because of the easy availability of a wide variety of aggregate as infill, designers rely on them for high quality urban and landscape architecture elements. By designing and constructing gabion baskets properly, they can meet both structural and architectural design criteria associated with a retaining wall.
But for the most effective use of gabions, you must select the right type of materials for constructing your gabions depending on the area of application and project-specific requirements. The most common materials include galvanized steel, stainless steel, raw steel, PVC coated steel, and copolymer plastic.
Below are different types of gabions and their specific applications in different environments:

Galvanized Steel Gabions
These gabions are constructed of either welded steel wire mesh or double twisted wire mesh that is hot dipped galvanized. Galvanized gabions show excellent results for protection against general exposure and are the most common type. Galvanized protection on gabion wires from zinc has proven to be an excellent general purpose option with its inherent corrosion resistance. They tend to have a useful life of around 25 years on average. However, the actual design life depends on many factors including water exposure, salinity and acidity of the soils and run-off, as well as environmental pollution.
PVC Coated Galvanized Steel Gabions
PVC coated gabions can be either welded wire mesh or double twisted woven mesh gabions. In both cases the steel core wires are fuse bonded with PVC coating after hot-dip galvanizing and applying primer. They make solid and rigid structures by providing excellent protection in extreme environments. The PVC coating layer provides added protection for use in environments where soil or water is acidic or polluted. The protective coating prevents the risk of corrosion and is ideal for retaining and erosion applications in freshwater.
Stainless Steel Gabions
Without the need for any extra process, stainless steel gabions have great natural features and are available in both 304 and 316L Stainless Steel. Aesthetically, stainless steel gabions easily incorporate with architectural designs and are available in a range of wire diameters and mesh sizes depending on the aesthetic preference and the material that will be used as fill. They’re fire-resistant and don’t require extensive care. They are resistant to corrosion or rust throughout the wire instead of just having a coating on the exterior of the wire. For applications around the ocean or highly corrosive soil, marine-grade stainless steel gabion materials can greatly improve the project life but it should be mentioned all steel when exposed to saltwater for extended periods of time will eventually rust.
Polypropylene Plastic Gabions
In contrast to conventional steel wire gabions, these UV-stabilized polypropylene gabions are a more affordable option that gives you long-term durability while allowing for flexibility in rough or uneven areas. PP marine gabions are non-reactive for the marine environment and are treated to maintain UV resistance. PP marine gabions are ideal for bodies of water where wave energy dissipation is needed to reinforce the shoreline. They also help in scour-protection and maintaining the integrity of structures close to the shoreline.
Raw Steel Gabions
If you are looking for an original rustic look for your project, raw steel gabions are cheap and readily available. While the patina they develop is very attractive due to the lack of coating on the steel the life span can be greatly dimenished depending on the severity of the environmental conditions. That is why these gabions are generally used in arid conditions or in applications where they are not exposed to large amounts of moisture. You can apply powder coating or a clear coat to increase the lifespan but this would require additional onsite maintenance.

Gabion baskets are widely used for slope protection, retaining walls, channel linings, noise barriers, etc. As the application scope continues to expand, the types of gabion basket derivatives are also quietly changing. Derivatives like gabion boxes and gabion mattresses emerge on the market. Gabion basket moves quickly towards a more specialized and refined direction. When purchasing gabion baskets, we are required to choose appropriate high-quality gabion baskets according to the characteristics of our project, so that we can get the maximum return with the minimum investment. So what factors should be considered in the purchase of gabion baskets?
Application
Generally, we have both double twisted gabion baskets and welded gabion baskets, which are produced by different production processes and are applied to different situations. Here we list their common applications. You can choose the right gabion basket according to your specific application.
Double twisted gabion basket refers to a rectangular box with double-twisted or triple-twisted hexagonal mesh fabric made of galvanized wire, PVC wire, or Galfan wire. It has been successfully used in a variety of applications including retaining walls, river banks, slope protection, channel linings, dams and culverts, etc.

Made of galvanized steel wire or Galfan wire, welded gabion basket generally has a solid structure, a durable service life and provides higher strength. It is commonly used in engineering constructions and architectural decorations like garden landscaping, trapezoidal gabion walls, interior decorations, gabion fireplaces and building facades.

Material
Gabion baskets are generally made of galvanized steel wire, Galfan steel wire and PVC coated wire. These materials have their own unique advantages; you can choose the right material according to their characteristics.
Material Description Galvanized steel wire High-quality galvanized low-carbon steel wire with a tensile strength of not less than 380 MPa. Hot-dip galvanizing is employed for surface protection. The thickness of the galvanized protective layer is manufactured according to customer requirements. The maximum galvanized amount is up to 300 g/m2. Galvanized steel wire is one of the most commonly used materials today. PVC coated wire Steel wires with a PVC or PE coating on the surface. Gabion baskets made of PVC coated wire can greatly increase the protection in the high pollution environments. In addition, there are various colors for your option to match with the surrounding environment. Galfan wire The composition of Galfan wire is 5% aluminum-zinc alloy or 10% aluminum-zinc alloy. When corrosion occurs, it will form an oxide layer; therefore, it provides excellent anti-corrosion and anti-wear performances. It remains staying in good condition even in the harshest environments. Besides, Galfan wire enjoys the longest service life, which is twice as long as that of galvanized steel wire.Structure
In addition to gabion boxes, we also have a similar product – gabion mattress . Similar like gabion boxes, gabion mattresses are divided into double twisted gabion mattresses and welded gabion mattresses, which are widely used in hillsides, river linings, bridge protection and river bank erosion applications.
Its main difference from gabion boxes is that the gabion mattress is relatively lower in height. Generally, it is 0.15 m, 0.17 m, 0.23 m, 0.3 m, and 0.5 m in height and presents a flat structure, which offers more stability. The gabion box is generally 1 m in height. You can choose corresponding products according to your application. For example, you can choose gabion mattresses for river bank slope protection as its flat structure provides more stability; you can choose gabion boxes for river bank elevation & reinforcement due to its height.
