Gabion

Gabion - a three-dimensional constructions of various shapes andsizes, made of twisted wire mesh hexagonal mesh and filled withstone. Grid double twisting used in gabions, provides highstructural strength. The grid is made of steel wire, galvanized orGalfan, thus ensuring long service life. In order to achievegreater resilience to external factors, is used to wire anadditional polymer coating.

Gabions are an alternative to concrete structures andhave several advantages.

• Permeability: Water easily penetrates through the gabions,without creating undue pressure on the structure and no effect onthe hydrology.
• Flexibility: Under the influence of variable loads, gabion canbe deformed without being destroyed. Where can crack concretestructure, gabion "adjusts" to changes in topography.
• Reliability and durability: Applied Materials, as well as highstrength braided mesh, provide long service life of gabions.
• Environmentally friendly: Over time, gabions, used forstrengthening, for example, the riverbed will accumulate algae,human pathogens, cleaning the water.
• Aesthetics: Over time, the gabion may accumulate soil in whichto grow plants, improving the appearance of gabion structures.
• Cost of manufacturing and installation: gabions delivered tothe installation site in the folded (effective transportation), andfilled with stones (effective installation).

Gabion widely used in building due to its easeof use - you only need to fill with rocks or pebbles.

It is used for the erection of fences, fences, walls, dams, theconstruction of dams decorative pools, ponds. During theconstruction of dams to enhance river beds during the constructionof embankments, strengthening the banks of rivers and reservoirs toprevent landslides and the collapse of the banks.

It is intended to strengthen the slope for landscaping and homegardens, laid on top of the gabion may blow sand or soil, planting.Performs the function of natural convection and metabolism and isvery environmentally friendly material.

Gabion can be made of galvanized steel mesh with hexagonal cellof the grid or PVC coated. In addition, gabion can be reinforcedwith steel rebar - available on request.

Each gabion is securely connected to adjacent gabion durablegalvanized wire mesh so that the whole structure can withstandlarge loads (erosion, wave, ice, ground pressure of the masses,etc.).

During the operation, as opposed to concrete, gabions are notsubject to destruction and cracks, due to design flexibility, whichin turn allows the construction of easily accept a draft of thesoil. Even the strong erosion of soil erosion at the base of gabionconstruction leads, often, only a slight deformation withoutcausing loss of strength and fracture. Over the years the strengthof metal mesh structures increases, due to the natural germinationof plant roots. Over time, merging with the environment, meshconstruction, with proper design solution can serve an unlimitedterm, have a kind of natural blocks, perfectly fit into thelandscape, becoming a single entity with him, maintaining andenhancing it.

Gabion - are beautiful, durable, environmentally friendly andfun!

How to Check the quality of gabion meshproducts?

• Twist defects, ligaments, strapping and ties mesh containergabion, diaphragms are determined visually by inspection;
• Determine the size of the cell between twist on opposite sidesof the hexagon in three places, gabion mesh products with anaccuracy of 1 mm. One of the measuring sites chosen in the middleof the gabion, the other two on the edges of at least two cellsfrom the edge of the gabion. In each of the measuring sites checkthe dimensions of ten consecutive cells;
• metal corrosion protection of wire should be robust andwithstand at least 5 turns of coiling in the rod with a diameterequal to 3 m diameter wire should not crack and break down to suchan extent that can be removed with the fingers;
• The coating material should not significantly change its colorwhen exposed to ultraviolet rays;
• Tensile strength at break of nets corresponds to the test loadat which the rupture of one of the wires of the control samplegrid. The control sample wire mesh should be 2 meters long and 1 mwide, and have one of two grid cells cut wire. Tensile tests of thecontrol sample wire mesh should be made on a hydraulic tensilebench. Half of the sample area of  the grid (in length) iscrimped to a fixed support, controlled by a uniformly distributedload is applied to the mobile tower, which secured second edge ofthe grid. When testing should not change the geometrical dimensionsof the grid in width;
• Length, width and height of gabion measuring tape at any pointor line with a scale of 1 mm
