Gabions serve two distinct functions depending on the context: a flexible structural solution for hydraulic works and retaining walls on difficult terrain, or a decorative architectural element with straight lines for modern design. The choice between triple-twist hexagonal mesh and welded mesh is not a nuance: one adapts and the other maintains a rigid shape. This comparison of the two MOLTEXO gabions will help you decide which one fits your project.
🎯 Choose in 10 seconds
- If you work in hydraulic engineering, retaining walls on soft ground, erosion control, or river channeling: go to Hexagonal Mesh Gabion
- If you work on architectural projects with modern aesthetics, urban furniture, or decorative walls: go to Welded Gabion
What to consider before choosing
Before buying, evaluate these four criteria. They define whether the gabion fulfills its structural function or remains a decorative element that fails under real load.
- Project type: structural or ornamental: Triple-twist hexagonal mesh gabions are the classic structural solution for hydraulic works and retaining walls that must adapt to ground settlement. Welded gabions have a rigid architectural aesthetic useful for decorative walls, planters, and urban furniture.
- Flexibility vs. structural rigidity: Triple-twist hexagonal mesh absorbs ground movements and progressive settlements without losing integrity — a critical advantage in hydraulic works with dynamic loads. Welded mesh maintains a rigid shape with straight lines — an advantage in modern architecture but a limitation on soils with irregular compaction.
- Exposure to salinity and continuous humidity: Both MOLTEXO gabions are galvanized, but the hexagonal one incorporates additional PVC coating over the hot galvanization, providing reinforced protection for Caribbean coastal areas and hydraulic works with continuous water flow. For dry interior or residential architecture, the galvanization of the welded gabion is sufficient.
- Natural permeable drainage: Both gabions allow natural drainage through the stone filling, preventing hydrostatic pressure buildup behind the wall. This property is a differential advantage compared to solid concrete walls in areas with high subsoil moisture or intense rainfall.
- Flexible triple twist that absorbs ground settlements
- Hot-dip galvanized + PVC coating against salt spray
- Natural permeable drainage through stone filling
- Integration with vegetation and sediments over time
- Deployment without heavy machinery with locally available stone
- Organic aesthetic less defined than welded gabions
- Less suitable for modern architectural projects
- Straight lines and rigid geometry for modern aesthetics
- Structural strength due to welded design
- Natural permeable drainage like hexagonal gabions
- Versatility of infill: stone, recycled glass, decorative finishes
- Quick assembly without heavy machinery
- No flexibility for progressive ground settlements
- Galvanized without PVC coating: less suitable for saline coastal areas
Hexagonal mesh box gabion: flexible structural solution
Box gabion with hot-dip galvanized triple-twist hexagonal mesh with PVC coating, dimensions 2 m × 1 m × 1 m. Designed for retaining walls in road works on soft soils with predictable progressive settlement; stabilization of slopes at risk of landslides, especially in tropical areas with intense seasonal rainfall; river channeling, bank protection, and hydraulic works with continuous water flow; rockfall barriers, coastal defenses, and architectural landscaping projects with a natural aesthetic.
Welded box gabion: rigid architectural aesthetic
Box gabion with welded steel wire mesh, dimensions 2 m × 1 m × 1 m. Designed for architectural retaining walls in residential, commercial, and urban infrastructure projects; decorative planters, landscape divisions, and exterior design elements with modern aesthetics; urban furniture (benches, tables, separators) in squares, parks, and pedestrian areas; facade cladding and industrial-architectural design elements in bars, restaurants, and interior design.

Before buying, define two facts: whether the gabion is structural or decorative, and whether it is exposed to coastal salinity or continuous water flow. The rule of thumb: hydraulic works or retaining walls on difficult ground → triple-twist hexagonal with galvanization + PVC; modern architecture or urban furniture → welded. The flexibility of hexagonal versus the rigidity of welded is the most important difference in real conditions.
Do not use welded gabions in hydraulic works with continuous flow or in coastal areas with marine salinity. Galvanization without additional PVC coating corrodes quickly in these conditions, compromising structural integrity. For hydraulic works, the only correct option is the hexagonal gabion with triple twist and double protection (galvanized + PVC).
Not sure which gabion you need?
If you are combining structural works with architectural elements, or have areas with different conditions (coastal part, inland part), ask the virtual assistant with details of the work and environmental exposure. You will receive an instant technical recommendation.

Frequently Asked Questions
What kind of stone do I use to fill gabions?
Angular quarry stone with a size larger than the mesh opening, so that it is not lost during handling. For hydraulic works, hard non-erodible stone is preferred; for architecture, ornamental stone, local natural stone, or even recycled glass can be used for decorative finishes in welded wire gabions.
How long does a hexagonal gabion last in a Caribbean coastal area?
Decades in standard operating conditions thanks to the double protection of hot-dip galvanizing plus PVC coating. Triple twist absorbs ground movements, and the galvanized+PVC combination resists marine salinity and continuous humidity. Without double protection, the lifespan is significantly reduced.
Do gabions look ugly over time?
It depends on the context. Hexagonal gabions blend into the landscape over time as vegetation grows between the stones, an advantage in environmental and natural landscaping. Welded gabions maintain their rigid modern aesthetic for decades—an advantage in architecture where visual permanence is sought.
