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.

Welded gabions are a popular solution in various construction and landscaping projects due to their durability, flexibility, and aesthetic appeal. They are versatile structures made from welded wire mesh, filled with stones, and used for erosion control, retaining walls, and decorative purposes. Here is a complete guide to frequently asked questions (FAQs) about welded gabions.
Welded gabions are rectangular or square cages made from welded wire mesh panels, which are then filled with stones or other materials. The panels are connected by spirals, clips, or other fastening systems to form a sturdy structure.
Retaining Walls: Used to stabilize slopes and prevent erosion.
Erosion Control: Protect riverbanks, shorelines, and slopes from erosion.
Landscaping: Create decorative features like garden walls, benches, and planters.
Sound Barriers: Reduce noise pollution in urban areas.
Fencing: Serve as durable and visually appealing fences.
Flood Control: Act as barriers to manage and redirect water flow.
Welded Gabion
Wire Mesh: Made from galvanized steel, PVC-coated steel, or stainless steel for enhanced durability and corrosion resistance.
Fill Material: Typically filled with natural stones, but recycled materials, concrete, or even decorative stones can be used.
Durability: Highly resistant to weathering and corrosion, especially when made with galvanized or PVC-coated wire.
Flexibility: Can adapt to different shapes and sizes, making them suitable for various applications.

Permeability: Allow water to pass through, reducing pressure build-up and improving drainage.
Aesthetic Appeal: Offer a natural look that blends well with the environment.
Ease of Installation: Simple to assemble and install without the need for specialized equipment.
Site Preparation: Clear the area and prepare a level base.
Assembly: Connect the wire mesh panels using spirals, clips, or other fastening systems to form the gabion box.
Filling: Fill the gabion with stones or other suitable materials.
Closing: Secure the top panel after filling to complete the structure.
Positioning: Place the gabion in the desired location and secure it if necessary.
Welded gabions can last several decades, typically ranging from 25 to 75 years, depending on the material quality and environmental conditions. Galvanized and PVC-coated gabions offer enhanced corrosion resistance, extending their lifespan.
Welded gabions require minimal maintenance. Periodic inspections are recommended to check for any signs of damage or displacement. If necessary, stones can be repositioned or replaced, and minor repairs can be made to the wire mesh.
Yes, welded gabions can be customized in terms of size, shape, and filling material to suit specific project requirements. Custom designs can also be created to achieve unique architectural or landscaping effects.
Construction: Welded gabions are made from welded wire mesh panels, while woven gabions are made from twisted wire mesh.
Strength: Welded gabions typically offer higher structural strength and stability compared to woven gabions.
Appearance: Welded gabions have a more uniform and rigid appearance, making them suitable for visible applications.
Yes, welded gabions are considered environmentally friendly. They use natural materials (stones) and can be filled with recycled materials. Their permeability supports natural water drainage, and their integration into the landscape can promote vegetation growth.
Welded gabions are a versatile and durable solution for various construction and landscaping projects.
