Galvanized Wire Mesh Stone Cages Rectangular Gabions

Rectangular Gabions Introduction

Rectangular Gabions can be used for making slope, rock,slope vegetation,rail-way or highway guardrail mesh stable. Also it can be made into basket, mesh mat for protecting dam which easily ruined by flood and lead to property losses. Therefore, application of gabion basket is the best solution of solving the problem that give dams lasting protection.

Rectangular Gabions specificaiton:

Material and Manufacture

Style 1 double-twisted mesh shall be manufactured from zinc-coated steel wire conforming to Specification A641/A641M, Class 3 coating, soft temper.

Style 2 double-twisted mesh shall be manufactured from Zn-5A1-MM-coated steel wire conforming to Specification A856/A856M, Class 3 coating, soft temper.

Style 3 double-twised mesh shall be manufactured from the same type of metallic-coated steel wire as Style 1 with an additional PVC coating extruded onto the metallic-coated steel wire.

Gabion wire mesh various characteristics:

Gabion mesh or gabion box has some obvious advantages ,such as corrosion prevention ,eletrostatic prevention ,age resistance ,corrosion-resistance ,compressive resistance ,sheaving resistance and improving the protective function in the highly polluted environment .This kind of mesh mainly used in river , sea and highly polluted area .

Rectangular Gabions Other information

The wire mesh shall consist of steel wire galvanized in accordance with BS 443 and fabricated in double twist woven hexagonal shape with the maximum linear dimension and area of opening limited to 100 mm and 80 cm2 respectively. The wire making the mesh shall have minimum tensile strength of 400 kg. Gabion baskets shall be rectangular in shape with edge manufactured into a securely connected selvedge suitable for prevention of unraveling or to have ability to resist pulling apart at any of the twist or connections forming the wire mesh when a single wire strand in a section is cut.

When the gabion length exceeds its width, it shall be equally divided by diaphragms of the same mesh and material as the gabion body to form individual cells whose lengths do not exceed the width of the basket.

The stones/rock to be used shall be well shaped, hard, dense and durable whose individual pieces shall weigh between 7 and 70 kg of which seventy per cent shall be 20 kg or larger.

The specific gravity shall not be less that 2.2. The stones in contact with the wire mesh fabric shall have a minimum size of 150 mm and those in the middle of the unit shall have minimum size of 100 mm.
