Introduction to PVC Coated Gabions with Galfan Technical Specifications

Gabions are an essential component in many civil engineering and landscaping projects. They are commonly used for retaining walls, erosion control, and channel linings. One crucial advancement in gabion technology is the use of PVC coated Galfan wire, which offers enhanced durability and longevity.

Expert Insights on PVC Coated Gabions

Many experts in the field have provided insights on the importance and benefits of PVC coated gabions. John Carter, a civil engineer with over 20 years of experience, notes, "The use of PVC coating on gabions provides an additional layer of protection against corrosion, making them suitable for environments with high levels of pollutants or salinity."

Dr. Emily Scott, a materials scientist, elaborates on the advantages of Galfan coating: "Galfan is an alloy of zinc and aluminum that offers superior corrosion resistance compared to traditional galvanization methods. When combined with PVC, it significantly enhances the lifespan of gabions, especially in harsh environments."

Technical Specifications

Wire Specifications

The wire used in the manufacture of gabions must meet specific standards to ensure durability and strength. According to ASTM A975-97, the steel wire is heavily coated with Galfan, followed by a PVC coating of nominal thickness 0.50 mm. Here are the key specifications:

• Tensile Strength: The wire must have a tensile strength between 372-470 MPa in accordance with ASTM A856.
• Elongation: The wire must have an elongation of not less than 12%, as specified in ASTM A370-97.
• Galfan Coating: The wire must comply with ASTM A975-97 style 3 coating requirements.
• Adhesion of Galfan: The Galfan coating must not flake or crack when the wire is wrapped around a mandrel, adhering to ASTM A856.

PVC Coating Characteristics

The PVC coating applied to the Galfan wire offers several technical characteristics that enhance the performance of gabions:

• Specific Gravity: 1.30-1.35 kg/dm³ in accordance with ASTM D792.
• Hardness: Between 50 and 60 Shore D, compliant with ASTM D 2240.
• Tensile Strength: Not less than 20.6 MPa, as per ASTM D412-92.
• Modulus of Elasticity: Not less than 18.6 MPa, in accordance with ASTM D412-92.
• Abrasion Resistance: Weight loss percentage must be less than 12%, according to ASTM D1242-92.
• Creeping Corrosion: Maximum penetration of corrosion from a square cut end must not exceed 25 mm after 2,000 hours in a 5% hydrochloric acid solution.
