High Strength Tecco Mesh For Rockfall Protection

High Strength Tecco Mesh For Rockfall Protection

Tecco mesh is made of high tensile strength steel wire 3.0mm 4.0mm or 2.0mm, with the tensile strength ≥1,770N/mm2, knotted ends ≥1.5 laps,normally the tecco mesh specifications are including G65/3 G65/4 G80/4 G45/2 G/40/2,All these designs enable the tensile strength of 1m with of mesh no less than 150kN/m, which can supply maximum protection to the slopes and peoples.

Specifications of Tecco Mesh

* Wire diameter: 3 mm, 4 mm or 2.0mm.

* Mesh type: Rhomboid hole, G65/3, G80/4, G45/2, G40/2 etc.

* Mesh size: Inscribed circle diameter is 65 mm, 80mm, 45mm, 40mm, 60mm, 55mm, 70mm, 75mm etc.

* Tensile strength: minimum 1770 MPa. (It's also available with 900Mpa, 1370Mpa etc.)

* Corrosion treatment: zinc-aluminum coated (Zinc coating ≥150g/m2. or heavily zinc coated (Zinc coating ≥200g/m2.)

* Zinc thickness: no less than 150 g/m2.

* Breaking load of single wire: 12.5 kN.

* Roll width: 1 m- 2.9m- 3.5 m- 3.9m.

* Roll length: 10 m- 20m- 30m.

Features of Tecco Mesh

* Safety. The tecco mesh can be used to stabilize any kinds of slope, including rocks and loose soil slopes.

* High tensile strength. The tecco mesh is made of high tensile spring wire, which the tensile strength is more than 1770 MPa, which can supply maximum protection to the slope and people.

* Environmental friendly. The rhomboid mesh can let the plants grow regularly and make the slope or maintain be more beautiful.

* Rhomboid mesh structure. This structure provide most stability for the geological conditions and can be tightly secured on the slope even on the irregular mountains.

* Knotted ends. Different from the chain link fence which has wrapped edge, the tecco mesh has knotted ends which can improve the tensile strength and stability of the structure.

* Lightweight. The tecco mesh has excellent strength-to-weight ratio, which make it easy to install and transport.

* Durable. The corrosive resistance surface let the tecco mesh has outstanding corrosive resistance performance, and the high tensile strength material make the tecco mesh be used for a long service life.

Tecco Mesh System

Tecco mesh system is a kind of active rockfall protection system, including tecco mesh, wire rope anchor, spike plate, boundary rope, sewing rope and steel clips. With the wire ropes and steel clips, the tecco mesh is fastened onto the mountain or slope surface tightly and firmly to block the large stones and reduce the damage of landslip or debris flow.

Tecco mesh system is an important active protection type system in the rockfall protection projects. This tecco mesh system mainly consists of tecco mesh, anchor, spike plate, boundary rope, sewing rope and specialized connection clips. The tecco meshes are fastened to the slope tightly by the anchors and spike plates through prestressed tension. Then the boundary rope, sewing rope and connection clips will reinforce the tecco mesh for solid and firm. When the landslide and debris flow comes, the large stones or debris will be blocked by the tecco mesh and reduce the attack to the ground.

Compared with other rockfall protection systems, the tecco mesh is made of high carbon steel wire with high strength and hardness. Tecco mesh system is the simplest structure among all the rockfall barrier systems.

Components of the Tecco mesh System

* Tecco mesh. Main part of the tecco mesh system is made of high tensile steel wire and have excellent corrosion resistance performance. The 1770 N/m2 tensile strength supply maximum protection for the slope and people.

* Steel anchor. The steel anchor is made of deformed steel bar with 25 mm diameter, it is mainly used to fix the tecco mesh onto the rock or soil slopes. It can supply the whole stability to the slope and tecco mesh.

* Claw type Spike Plate. The claw type spike plate is commonly used with nails to fasten the tecco mesh onto the slope firmly. The claw design make the spike plate a more stable and firm structure.

* Soil or rock nails. Used with claw type spike plate to fix the tecco mesh onto the mountain. High tensile strength and solid structure make it be long service life and good condition.

* Connection Clips. The connection clips are used to connect the neighbor tecco mesh rolls firmly. It is an alternative to the sewing rope and the connection is commonly without overlap.

* Sewing rope. It is used for connecting the neighbor tecco meshes. And the connection is commonly have overlaps. It can be used to replace the clips.

* Boundary rope. Pass through the tecco mesh and then be fixed onto the anchor for tecco mesh and system stability.

Applications of Tecco Mesh System

* The tecco mesh system is suitable for soil texture and similar slope surface. It can not only stabilize the slope and replace the traditional mortar slag stones structure, it is also environmental friendly, which can ensure the plant growth.

* It can be used in the strong weathered rock slopes, bank strengthening.

* It can be used to control water and soil loss and external-soil spray seeding.
