Gabions are a type of construction material fabricated from galvanized steel wire, available with or without a PVC coating. They are utilized in various civil engineering applications, including retaining walls, gravity structures, and more. Typically, preference is given to galvanized steel wire gabions with a PVC coating. But why is this the case? What are the advantages of applying a PVC coating to galvanized steel wire for gabion construction? Let’s explore this topic with Phu Thanh Phat!
What are PVC Coated Gabions?
PVC coated gabions are gabions manufactured from galvanized steel wires that are further coated with PVC. These wires are woven into a double twisted hexagonal mesh, which is then assembled and connected to form a box-like structure. The detailed structure of a gabion box comprises a continuous front panel, base, back panel, and lid, combined with diaphragms and transverse binders made of lacing wire or steel fasteners. The gabion is divided into cells by these diaphragms to prevent the displacement of the infill material (typically rock) after placement.
Why Use PVC Coated Gabions?
PVC coated gabions share a similar base construction with standard galvanized gabions. However, in PVC coated gabions, after the galvanization process, the steel wire undergoes an additional step where a layer of PVC is applied externally. This is also known as a polymer coating. This process significantly enhances the lifespan of the gabion’s structural wires by providing superior resistance to electrochemical corrosion from the surrounding environment and improving UV resistance. It also protects against catalytic agents that can negatively impact the durability of the gabion when exposed to unfavorable natural conditions that could degrade the zinc coating of the woven steel wire.
This is particularly beneficial in hydraulic structures and earth retaining walls located in areas with aggressive geological environments, such as acidic or alkaline soils. The added polymer (PVC) coating on the exterior provides these gabions with several optimized performance characteristics compared to conventional galvanized gabions:
- Feature: PVC Coated Gabions;
- Composition: Galvanized steel wire with PVC coating;
- Durability: Rust-resistant;
- Environmental Resistance: Resistant to UV radiation, chemicals, catalytic agents, corrosion;
- Applications: Suitable for construction in all terrain conditions, including saline and acid sulfate weak ground environments;
- Color: Variety of colors (PVC coating color);
- Prevalence: Widely used in almost all types of construction projects, including underwater structures and those exposed to highly oxidizing environments.
