Core Product Advantages

• Strong Blast & Fragment Blocking Performance

  Thick high-tensile welded steel frame + sand filling layer disperses blast energy step by step, weakens shock wave transmission and blocks shrapnel splashing. Multi-row stacked structure can reach high anti-explosion rating, ideal for chemical depots, ammunition storage, oil & gas facilities high-risk protection projects.

• Foldable Modular Design, Ultra-Low Logistics Cost

  Empty cages fold flat for container shipment, saving over 70% transport space compared with pre-assembled products. Standard single-cell/multi-cell units connect quickly via spiral springs, workers finish continuous protective wall within hours without concrete pouring.

• Multi-Layer Anti-Corrosion Treatment, Long Outdoor Service Life

  Three surface treatments optional: hot-dip galvanized, Galfan Zn-Al alloy coating, PVC coated welded mesh. Geotextile liner adopts UV & acid resistant non-woven fabric, anti-tear, anti-aging. Galfan version service life reaches 20–30 years in coastal, chemical and humid outdoor environments.

• Dual Function: Anti-Blast & Emergency Flood Control

  Same welded gabion bastion can serve two purposes: fill stone/sand as blast wall for explosion isolation; quickly stack to form temporary flood barrier during flood disasters, block water flow and prevent embankment collapse, multi-scene reusable to cut project procurement cost.

• Easy Disassembly & Reusable, High Cost Performance

  No permanent foundation needed. After project completion, empty and fold cages for storage, transfer to other construction sites, military camps or shooting ranges for secondary use. Compare with one-time concrete blast wall, total engineering cost reduced by 40%+.

• Customized Size, Mesh & Liner Options

  Support MIL standard H1-H7 military sizes, custom wire diameter (3–6mm), mesh aperture 50×50/76.2×76.2/100×100mm; geotextile liner available in sand beige, olive green, gray, black, different gram weight (200–400g/㎡) for heavy-duty defense demand.

Step-by-Step Installation Guide

Step1: Unfold folded welded gabion cages on flat ground, straighten mesh panels and fix liner wrinkles.

Step2: Connect single cages end to end with galvanized spiral springs to form continuous wall line according to design length.

Step3: Fill sand/gravel evenly layer by layer, compact filler to keep wall rigidity, avoid hollow gaps.

Step4: Fold geotextile liner top edge inward, cover and lock cage upper frame to prevent filler overflow.

Step5: Stack multiple layers vertically for higher anti-blast requirement, connect upper & lower cages tightly to form integral blast wall system.

Packaging & Global Shipping

All welded gabion blast cages are folded flat, bundled with steel straps, plastic film wrapped to avoid scratch. Spiral springs and liner spare parts packed in separate export cartons. Suitable for 20GP/40HQ sea containers, long-distance ocean transport without deformation or corrosion, meet FOB/CIF/DAP international trade terms.

FAQ 

Q1: What’s the difference between welded gabion blast wall and twisted gabion mesh?

A: Welded blast bastion adopts full spot-welded rigid mesh, high impact resistance, specially for anti-explosion defense; triple twisted gabion is flexible for river slope landscaping, cannot bear blast shockwave.

Q2: Can this defensive barrier be reused multiple times?

A: Yes. Empty sand/stone after use, fold flat cages for storage, transfer to other sites repeatedly, no structural damage under normal use.

Q3: Which finish suits coastal chemical industrial park?

A: Galfan zinc-aluminum coated welded mesh + 400g anti-corrosion geotextile liner, excellent salt spray & acid resistance, service life over 25 years.
