The columns are formed from hot-dipped galvanized sheets, which are pressed into shape and then cut and welded. They are then coated with a double layer of anti-rust paint before being transported to the site for concrete pouring and burial.

The construction method for the metal highway guardrail mesh involves welding, processing, and bending the mesh panels according to specifications. After processing, the mesh is hot galvanized. The installation is then carried out on-site. Based on the completion of layout and positioning work, the foundation and posts are constructed as required, followed by the installation of the mesh panels.

Construction Sequence and Techniques

1. Infrastructure Engineering: The project employs segmented construction along the entire route. The construction follows the straight-line principle while also attempting to level uneven terrain to form straight slopes or grades, minimizing structural undulations. The foundation location is determined, followed by excavation of the foundation pit, pouring the foundation, and finally, backfilling.

2. The column engineering metal highway guardrail posts are in the shape of peach posts, which must be coated with plastic before being formed from hot-dipped galvanized sheets. After the posts are manufactured, installation should be based on the foundation construction situation.

3. The installation of the Peach-shaped Column Fence Mesh differs from that of other types of fences, such as wave-type fences, sports field fences, railway fences, and highway guardrails. These are typically installed by setting up the posts first and then connecting the mesh. However, the Peach-shaped Column Fence Mesh cannot be installed this way. If the posts are set up first, the mesh cannot be properly connected.
