 SNS is short for safety netting system,also know as diamond-shaped steel wire mesh,ring mesh,high-strength steel wire grid. We can make both active protection system and passive protection system with steel wire ropes as major components,the covering protection type is called active system,the holding protection type is called passive system.So,SNS has two basic types of flexible security system technology and products to prevent geological disasters of various slopes and avalanche slope,bank erosion,blasting stone fly,falling objects and other hazards.
The whole system is composed of high-strength steel wire, bolt and other installation components.
Feature:
SNS protective mesh is one kind of new technical product completely changed the traditional ideas of slope protection. This product has incomparable advantages compared with other similar products. When works as products withstanding huge impulse, it can avoid the damage may caused by the partial centralism stress, with the lengthened response time; increased mesh point surface; at the same time, it receives the partial stress with the whole.  The SNS product is suitable for any complex terrain, while maintaining the primitive landform. SNS product has mesh opening allowing good vision, convenient for planting trees and grasses and good for the environmental protection. It is simple for installation to save time. The product has standard components that do not need site further processing. Simple machine, less labor and a small quantity of earth and stone foundation are needed for the building block system installation quickly and easily. It does not need to excavate massively, does not need the massive material, does not disturb the neighboring buildings normal operation and other construction function, hence to avoid the heavy economic loss caused by “the disturbance”.
Application: This product is widely used in the railway, highway, the mine, the water and electricity project, the tourist site, the river course and in the municipal engineering,etc.
 
Safety netting system specification can be made according to customers' request.
TECCO MESH
This is a special slope stabilization system,consist of below components
 1) High Tensile Strength Wire Mesh
Wire strength: 256 ksi (1770 N/mm2)
Wire diameter: 0.125 inch (3mm)
Material: Galfan Wire (95% Zn / 5% Al coating)
Coating: 0.41 oz/ft2 min,125g/m2
Mesh aperture: 3.3"(83mm) x 5.6"(143mm)
Mesh height: 0.43" (11mm)
Mesh strength: 150 KN/m
 2. Spike Plates
To insure optimal transfer of forces from the mesh to the anchors,
a special spike plate has been developed.These plates are placed over the anchor heads and tightened in order to pre-tension the mesh onto
the slope.The plates are galvanized and have dimensions of
13.0" x 7.5" x 0.4"(330mm x 190mm x 10mm).
3.Compression Claws
 In order to take full advantage of the high tensile strength of the
mesh,a special fastener is required to connect the individual mesh
panels together.These claws are hot dipped galvanized and consist
of 0.25"(6mm) thick steel spiral.
4.Anchors
The main anchors of the system are installed in a grid typically ranging from 6.6 to 13.1 ft(2.0m to 4.0m)horizontal and vertical spacing.Actual spacing depends upon the results of site analysis and modeling.Anchors consist of commercially available steel bars ranging from 1.0 to 1.25"(25 to 32mm).Self-drilling grout injection anchors are also permitted.Additional anchors may also be used to provide added support at boundaries and in low points and hollows.
  
SPIDER MESH
Spider slope stabilization system also know as rockfall drapes,spider net,spider rope net.
Components: high strength carbon steel wire sheet,prestressed anchor bar,special anchor backing plate;
Fixed mode: prestressed anchor bar,special anchor backing plate;
Bearing capacity: It is better than all of the current flexible slope stability system;
Design method: Based on the theory of RUVOLUM design system;
 Application: Soil slope and rock slope stability reinforcement,various types of boulder rock reinforcement,can also be combined with deep anchorage measures for slip control.
Breaking force: 195-220KN/m
Aperture shape: diamond
Aperture size: 292 x 500mm (+/-5%)
Wire diameter: 3.0mm
Monofilament intensity: Not less than 1770N/mm2
Strands structure: 1 x 3
Zinc mass: Not less than 150g/m2
Feature:
1)Simple structure,installing more efficient;
2)New structure design theory,model and layout of anchor selection more targeted;
3)Special mesh and anchor form,bring greater slope pre-pressure,more optimized system stress transfer;
4)Longer anticorrosive life;
5)More economic investment.
