Tecco Mesh – Active Rockfall Barrier of slope protection
Product description
Tecco mesh is made of high carbon steel wire. Tecco mesh system is a kind of active rockfall barrier 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.

Components
The TECCO system consists of four main components that are carefully coordinated with each other:
1). TECCO steel wire mesh
TECCO mesh is made of high-tensile steel wire with an ultimate tensile strength of 1770 N/mm2.
2). TECCO spike plates
Rigid spike plates that are reinforced with ribbing ensure optimal load transmission from soil or rock anchors to the TECCO mesh.These plates are placed over the anchor heads and tightened to pre-tension the mesh onto the slope.
3). TECCO connection clips
The connection clips high-strength steel wire connection clips enable mesh sections to be joined without overlapping and still guarantee one hundred percent transfer of forces.These claw are hot dip galvanized and consist of 0.25"(6mm) thick steel spiral.
4). Soil or rock nails
Adapted to the local soil and rock static requirements, the TECCO mesh can be anchored in accordance with our dimensioning concept with commercial soil or rock nails.The main anchors of the system are installed in a grid typically from 6.6 to 16.4 ft (2.0 to 5.0m) horizontal and vertical spacing.Actual spacing depends upon the results of site analysis and modeling.Anchor consist of commercially available steel bars ranging from 1.0 to 1.25 ft (25 to 32mm).Selfdrilling grout injection anchors are also permitted.Additional anchors may also be used to provide added support at boundaries and in low points and hollows.
Feature
High safety and tensile strength.
Rhomboid mesh structure for stability.
Corrosion and rust resistance.
Environmental friendly for plant growth.
Easy to install and transport.
Durable and long service life.
Application
The tecco grid is usually installed on soil or rocky textured surfaces such as mountains and slopes to prevent falling rocks and to ensure plant growth. In addition, it can be used to control water, soil loss and external soil spray sowing.
