OEM Gauge Wire for Gabion Stone Cages

Gabion stone cages rely on tensile wire to maintain structural integrity under lateral earth pressure and dynamic loads. The gauge, tensile strength, and corrosion protection of the wire directly influence cage deformation resistance and service life.

Technical Specifications

Typical OEM gauge wire for gabion applications is supplied as cold‑drawn steel wire with a circular cross‑section. Diameter is expressed in American Wire Gauge (AWG) or metric mm, and the wire is often hot‑dip galvanized or coated with a polymer layer to achieve required corrosion resistance.

Property	Typical Value	Unit	Notes
Diameter (AWG)	8 – 12	AWG	Corresponds to 2.0–2.6 mm
Tensile Strength	450 – 550	MPa	Cold‑drawn low‑carbon steel
Elongation at Break	10 – 15	%	Ensures ductility during installation
Galvanizing Coating	55 – 85	µm Zn	Hot‑dip, per ASTM A123

Material Options

Base steel grade, coating type, and auxiliary additives are selected according to site‑specific exposure conditions such as salinity, pH, and UV intensity. The following material combinations are commonly offered.

• Low‑carbon steel (SAE 1008/1010) with hot‑dip galvanizing (Zn 55–85 µm)
• Low‑carbon steel with Zn‑Al alloy coating (Zn‑5Al‑MM) for enhanced corrosion resistance
• Stainless steel grade 304 or 316 wire for aggressive marine or industrial environments
• Polymer‑coated (PE or PP) over galvanized core for abrasion protection

Applications in Gabion Structures

The wire forms the mesh that confines stone fill, transferring loads from the retained soil to the gabion body. Adequate wire gauge prevents local buckling of the mesh under stress concentrations at panel corners and ensures uniform stress distribution across the cage.

In retaining walls, the wire must resist corrosion from groundwater and soil chemicals while maintaining enough flexibility to accommodate settlement without cracking the galvanized layer. In channel linings, abrasion resistance from flowing debris is a key selection criterion.

Customization Capabilities

OEM suppliers adjust wire diameter, tensile strength, coating thickness, and coil length to match project specifications. Custom lengths reduce field splicing, while tailored tensile grades optimize material cost versus safety factor.

• Diameter: 1.8 mm to 3.2 mm (AWG 13 to 7)
• Tensile strength: 350 MPa to 620 MPa
• Galvanizing thickness: 30 µm to 120 µm
• Coil weight: 15 kg to 50 kg (standard) or custom spools
• Pre‑cut lengths with end‑loop or hook terminals

Quality Assurance and Testing

Quality control follows a documented procedure that verifies dimensional tolerance, mechanical properties, and coating adherence before shipment. Each batch undergoes sampling according to ISO 9001‑based sampling plans.

• Diameter measurement with laser micrometer (±0.01 mm)
• Tensile test on universal testing machine (strain rate 10 mm/min)
• Elongation and yield point determination
• Coating thickness via magnetic‑induction gauge (ASTM A90)
• Adhesion test (knife‑test or bend test) for polymer overcoat
• Visual inspection for surface defects, splines, or weld irregularities

Packaging and Logistics

Wire is supplied on steel or wooden reels, wrapped in stretch film, and placed in corrugated cartons or wooden crates to protect against moisture and mechanical damage during transit. Export shipments include desiccant packs and corrosion‑inhibiting vapor barriers where required.

Standard pallet dimensions accommodate forklift handling, and each package is labeled with part number, heat trace code, and quantity for easy inventory management.
