Gabion Box
A gabion box, also known as a gabion basket, is a rectangular container made of double-twisted hexagonal wire mesh, divided into cells by diaphragms and filled with stone on site to build retaining walls, river protection and erosion-control structures.

What is a gabion box?
A gabion box is made from one continuous base-front-back panel of hexagonal mesh, with separate ends, diaphragms and a lid. All panel edges are reinforced with a thicker selvedge wire. Diaphragms divide the box into 1 m cells, so the stone stays evenly packed and the box keeps its shape.
On site, the boxes are unfolded, laced together, filled with stone and closed. The finished structure is heavy, flexible and permeable: it follows ground settlement without cracking and lets water drain through, which makes it ideal for retaining walls and river works.
Reno mattresses are shallow gabions, 0.17–0.3 m thick, used to line riverbeds, channels and slopes. Boxes and mattresses are supplied folded and bundled for transport.

Frequently Asked Questions
What is the difference between a gabion box and a Reno mattress?
A gabion box is usually 0.5–1 m high and used for walls. A Reno mattress is 0.17–0.3 m thick and used to line riverbeds, channels and slopes.
Why are diaphragms needed?
Diaphragms divide the box into 1 m cells, which keeps the stone evenly distributed and stops the box bulging during filling.
What stone should be used to fill gabions?
Hard, durable stone larger than the mesh opening, typically 100–250 mm for boxes and 75–150 mm for mattresses.
How are gabion boxes delivered?
They are folded flat and bundled, then unfolded, assembled and filled on site. Lacing wire or C-rings are supplied for assembly.
Which coating lasts longest?
Galfan zinc-aluminium alloy lasts longer than standard galvanizing. For sea water or polluted water, choose PVC coating over galvanized or Galfan wire.
What information do you need for a quotation?
Box or mattress sizes and quantities, mesh and wire sizes, coating, fastener type, and the destination port.
