Galfan & PVC coated hexagonal wire mesh for rockfall barriers
Product Description:
Rockfall barrier is a rockfall protection system which is used to prevent rocks falling down the road to protect pedestrians and vehicles from danger. This rockfall barrier system contains 4 types:
Hexagonal wire mesh.
tecco mesh.
spider spiral rope mesh.
wire rope nets.
Hexagonal wire mesh is made of hot-dipped, PVC coated or galfan steel wires. The wires are double twisted and the edge of the mesh is reinforced by a thicker wire – selvedge wire. It can be used individually or combined with other meshes as active rockfall barrier. Fastened by anchors, bolts and steel cables, hexagonal wire mesh is strong and firm enough to block the rocks or debris and minimize the damage of natural disasters.
| Hole size (mm) | Mesh wire(mm) | Side wire(mm) | Binding wire(mm) | Max width |
| 60X80 | 2.0~2.8 | 3.0~4.0 | 2.0~2.2 | 4M |
| 80X100 | 2.0~3.0 | 3.0~4.0 | 2.0~2.2 | 4M |
| 80X120 | 2.0~3.0 | 3.0~4.0 | 2.0~2.2 | 4M |
| 100X120 | 2.0~3.0 | 3.0~4.0 | 2.0~2.2 | 4M |
| 100X150 | 2.0~3.0 | 3.0~4.0 | 2.0~2.2 | 4M |
| 120X150 | 2.0~3.0 | 3.0~4.0 | 2.0~2.2 | 4M |
Features
High tensile strength. Hexagonal wire mesh is double twisted structure which makes it can withstand the impulsive force of falling rocks and without unraveling in the event of wire breakage.
Corrosion and rust resistance. Heavy zinc coating supplies excellent and long term corrosion and rust resistance. Additional, the PVC coating makes the hexagonal wire mesh be used in more aggressive environments and longer service life.
High durability & stability. Boundary rope and wire rope anchors can enclose the hexagonal wire mesh onto top and foot of mountains for durability and stability.
Improve firmness. We use prestressed anchors to fasten the hexagonal wire mesh firmly onto mountains, even onto the uneven mountain surface to improve firmness.
The rock barriers are mainly used in:
Roadside.
Tunnel construction.
Soil slope protection.
Private areas.
Highway construction.
Coastal protection.
