358 high security fence is a high-strength, high-security welded fence commonly used in power plants, embassies, research institutes, borders, prisons, military bases, and other places with high security and privacy requirements. Combined with 358 high security fence installation scenarios, we provide the appropriate installation guidance.

Step 1: Preparation & planning

Check ground conditions and underground pipelines. And prepare the required materials such as 358 fence mesh, posts, clamp bars / spider clips, bolts, nuts, metal washers, levels, etc.

Step 2: Mark the installation site

Mark the location of each post according to the width of the fence mesh.

Step 3: Post installation

Choose the fixing methods of the posts according to the ground soil conditions and the need for flexibility in the installation:

Step 4: Fix fence

Combined with the different ease of dismantling and installing the fence mesh and different structural stability, choose the fence mesh fixing method:

Clamp Bar Installation

Clamp bar installation provides a stronger connection and the fence mesh is easier to remove from the posts. Place two fence mesh edges overlapping between the post and the clamp bar when assembling, thread the bolt through the hole in the clamp bar and the hole in the fence panel, and then place washers on both sides of the bolt. Tighten the nuts and make sure the connection is tight.

When fixing the fence meshes with end posts and corner posts, the fixing methods are different:

Spider Clip Installation

Spider clip installation is more flexible and is easier to adjust to different terrains and height fluctuations. In addition, compared to clamp bar installation, spider clip installation is more economical as it requires less material. The fence is placed in front of the post and the prepared spider clips are clamped to the edges of the two adjacent fence pieces when assembled. The fence panels are then secured by special bolts and torque screws through spider clips to keep the fence panels stable.

When fixing the fence meshes with end posts and corner posts, the fixing methods are different:

Note: The height from the ground to the top of the post in a dig-in installation needs to be 5 cm higher than the height at which the fence is to be installed.

Step 5: Check & adjustment

Finally, check all connection points to ensure that the fence mesh has been properly installed and make any necessary adjustments to ensure the stability and appearance of the fence.
