Heavy Galvanized Gabion Basket for Retaining Walls | ASTM A975 Standard
Heavy Galvanized Gabion Basket for Retaining Walls | ASTM A975 Standard
Engineered for heavy-duty earth retention, hydraulic erosion control, and soil stabilization, these heavy galvanized gabion baskets are fabricated from high-tensile, double-twisted hexagonal woven wire mesh. Fully compliant with ASTM A975 specifications, they provide a monolithic, flexible, and free-draining gravity retaining structure designed for long-term geotechnical performance.

Key Engineering Advantages
-
Structural Flexibility: The double-twisted woven structure absorbs differential soil settlement without fracture or loss of structural integrity, outperforming rigid concrete retaining systems.
-
Natural Drainage & Permeability: High voids ratio eliminates hydrostatic pressure buildup behind the wall, preventing water-logging and reducing the need for complex auxiliary drainage pipes.
-
Corrosion Resistance: Heavy hot-dip zinc coating ensures cathodic protection in aggressive soil and freshwater environments, yielding an extended service life exceeding 25–50 years.
-
Non-Raveling Construction: The double-twist mechanical lock ensures that individual wire cuts or breaks do not unravel the surrounding mesh panel.
-
Environmental Integration: Promotes natural vegetation growth over time as soil deposits settle into the rock matrix, creating a bio-engineered, aesthetically blending green wall.
Primary Applications
-
Gravity & Reinforced Retaining Walls: Roadway cutting stabilization, railway embankments, and commercial property earth retention.
-
Channel Linings & Riverbank Protection: High-velocity hydraulic revetments and scour protection.
-
Bridge Abutments & Culvert Wing Walls: Load-distributing flexible footings around civil infrastructure.
-
Perimeter Defense & Noise Barriers: Heavy-duty physical security perimeters and rockfall mitigation.
Packaging & Assembly
-
Delivery Condition: Folded flat and bundled into compact export bales (50–100 units/pallet) to optimize container loading.
-
Assembly Accessories: Supplied with pre-calculated spools of heavy galvanized lacing wire or C-rings (pneumatic fastening compatible) exceeding ASTM tensile requirements.
