Gabion Mesh — Technical Specifications, Coatings, and Project Solutions

Haobo Metal's Gabion Mesh is the industry-standard solution for retaining walls, riverbank stabilization, and erosion control. Manufactured from high-tensile galvanized steel wire with a hexagonal double-twist structure, our gabion products meet EN 10223-3 and ASTM A975 standards. With over 20 years of export experience to 50+ countries, we deliver certified quality at factory-direct pricing.

1. Technical Specifications

Every gabion mesh order comes with full material test certificates (MTC) and third-party lab reports. Below are our standard specifications — all parameters are customizable to your project requirements.

Parameter	Standard Range	Custom Options
Wire Diameter	2.0mm – 4.0mm	Up to 5.0mm for heavy-duty walls
Mesh Opening	60×80mm, 80×100mm, 100×120mm	Custom sizes available
Coating Type	Hot-dip galvanized (275 g/m²)	Galfan (Zn-5%Al), PVC coated
Tensile Strength	350 – 500 MPa	Up to 550 MPa for seismic zones
Zinc Coating Mass	60 – 250 g/m²	275+ g/m² for marine environments
Selvedge Wire	3.0mm – 4.4mm	Matching or thicker than mesh wire
Standards	EN 10223-3, ASTM A975	BS 8002, AS 2758 compliant

2. Gabion Basket Configurations & Sizing

We manufacture gabion baskets in standard and custom sizes. Each basket is reinforced with internal diaphragms (partitions) at 1-meter intervals to prevent bulging under load.

• Standard Box Sizes: 2m × 1m × 1m | 3m × 1m × 1m | 4m × 1m × 1m | 2m × 1m × 0.5m
• Mattress Sizes: 6m × 2m × 0.3m | 6m × 2m × 0.5m | 4m × 2m × 0.3m
• Roll Form: Supplied as flat-packed mesh rolls for on-site assembly — 50m² to 100m² per roll
• Pre-assembled: Factory-welded baskets ready for immediate filling — reduced labor costs by 40%
• Lacing Wire: 2.2mm galvanized wire, supplied at 5% of total mesh weight, free with every order

3. Coating Selection Guide: Galvanized vs Galfan vs PVC

Choosing the right coating determines your gabion structure's lifespan. Here's a practical comparison based on real-world performance data:

Coating	Lifespan	Best For	Cost Index
Hot-Dip Galvanized	30–50 years	General retaining walls, rural areas	100 (base)
Galfan (Zn-5%Al)	50–75 years	Coastal/marine, acidic soil	115–125
PVC Coated	40–60 years	Chemical plants, decorative walls	130–150
PVC + Galfan Core	75–100 years	Critical infrastructure, permanent	160–180

4. Applications Across Infrastructure Projects

Our gabion mesh has been deployed in over 500 infrastructure projects worldwide. Key application areas include:

• Retaining Walls: Flexible gravity walls up to 15m height — ideal for seismic zones where rigid concrete walls would crack
• Riverbank Protection: Scour-resistant revetments and bank stabilization — permits natural vegetation growth between stones
• Highway Embankments: Cut and fill slope protection with integrated drainage — eliminates hydrostatic pressure issues
• Bridge Abutments: Flexible wing walls that absorb impact and vibration without structural failure
• Landscape Architecture: Decorative gabion walls, seating elements, and noise barriers — available in colored stone fill
• Mining & Tunneling: Portal stabilization and underground support structures — rapid deployment

5. Quality Control & Testing Procedures

Every gabion mesh shipment undergoes a rigorous 7-point inspection before dispatch:

1. Raw Material Inspection: Steel wire chemical composition analysis per batch
2. Tensile Testing: Wire tensile strength and elongation tested to EN 10218-1
3. Zinc Coating Test: Preece test (copper sulfate dip) to verify coating uniformity and minimum mass
4. Mesh Weave Check: Visual + mechanical inspection of double-twist integrity and opening accuracy
5. Selvedge Verification: Edge wire diameter and attachment strength testing
6. Salt Spray Test: ASTM B117 for corrosion resistance validation (marine-grade orders)
7. Final Dimensional Check: Roll dimensions, weight, and packing quality verification

All test results are documented in the Material Test Certificate (MTC) provided with every shipment. Third-party inspection by SGS, Bureau Veritas, or TÜV available on request.

6. Ordering & Delivery Process

Our standard order-to-delivery timeline is 15–25 days, depending on order volume and customization:

• Day 1–2: Receive your inquiry → our engineer reviews specifications and provides technical proposal
• Day 2–3: Proforma Invoice (PI) issued → 30% deposit confirmation
• Day 3–15: Production — wire drawing, galvanizing, mesh weaving, quality testing
• Day 15–18: Packing into seaworthy containers or pallets → loading
• Day 18–25: Ocean freight departure → shipping documents emailed (B/L, MTC, packing list, CO)
