rock fall WIRE netting - in stock

Our High-Resistance Rockfall Netting is a double twisted 11ga (0.120), hexagonal woven wire mesh that features a non-raveling design, superior corrosion resistance, and unique mechanical characteristics.

The double twisted mesh design offers resistant to unraveling when wires abrade. It is ideally suited for difficult rock face problems such as fractured stones are trapped and confined against the slope should isolated wires fatigue from prolonged stress. In addition, this type of double-twisted netting has the high mechanical resistance required to prevent the danger of sudden rock shock loads and dissipate rock fall energy created from loose fractured rock.

Rock fall netting is typically used in areas where there is a risk of rockfall, such as highways, railways, mining operations, and urban areas located near steep slopes or cliffs. It is a cost-effective and practical solution for protecting people and property from the rockfall hazards.

Specifications

Rock fall netting roll sizes: 6' x 150' - 12' x 150'- 15' x 150' - 6' x 300' - 12' x 300' - 15' x 300'
Mesh Opening: 3" x 4" hex nominal (8 x 10 cm)
Wire Size: 11ga (0.120)
Wire spec: QQW-461H, STM-A641, available in galvanized and galvanized with PVC protective coating.

In severely corrosive environments or in seaside locations, the use of heavily zinc-coated and PVC-coated wire mesh is recommended. The PVC coating, .0216 thick, is applied to the wire core by the extrusion method. This characteristic does not alter the remarkable flexibility of the product, which has been extensively time tested on gabions and Reno mattresses.

ANCHORING THE TOP:

At the top of the slope, the netting must be firmly anchored to the soil and seams overlapped approximately 1.5 ft.
Cracked hard rock not subject to deterioration: Simple and/or double expansion bolds of 1/2-inch diameter placed on 3 ft to 6 ft centers.
Compact rocks subject to deterioration: Drill a series of holes at least 1.5 ft deep on 6 ft centers into the rock. Steel reinforcing bars (#4 or #5) will be inserted, hooked and then anchored by filling the holes with grout, mortar or special resins.
Compact soils: At the same distance, steel reinforcing bars (#6), 2.5 ft long, shall be driven into the soil and fabricated with hooks to which the netting shall be tied.
Organic and soft soils: Use anchoring bars (0.5 in to 0.6 in diameter, at 5-6 ft long and 1.5 ft centers buried in concrete. The netting shall be tied to the bars by means of a continuous steel rope.
Eye bolts may be substituted for reinforcing steel. Steel cable (3/8 to 1/2 in) is then laid out in a designed grid system and tied to the mesh and the eye bolt is attached to the cable grid with interlocking fasteners.

Anchoring the Face:

If necessary, before laying the netting, the slope must be reclaimed, blasting to remove all loose rocks and boulders. The netting sheets shall be carefully tied together using lacing wire or interlocking fasteners at the sheet overlap.
Where overlapping occurs, usually at the vertical splice of adjoining sheets, a minimum one-foot overlap is recommended. Horizontal splices may be required as job site conditions dictate.

Treatment of the Toe:

In order to carry out the removal of debris more easily, the netting is simply left loose at its base for approximately 1 ft or to contain the debris rolling down the slope and piling up at the toe of the protection, the netting is anchored at its base. This anchorage, carried out according to the above-mentioned methods, must allow for the removal of accumulated debris from time to time.
