Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to reach the utility, that is appropriate and the use of hexagonal cage used to fill stone, fixed river, can avoid river erosion bring water and soil loss. In the civil engineering project, the hexagonal cage is considered appropriate and the use of similar particle size volume particle filling, cage between the formation of a mesh wall, which is the stone cage mesh retaining wall.taining wall.

PVC coated barbed rope is widely used for railway highway protection, but also for safety protection of rivers, embankments and seawalls, so as to better protect the safety of people and animals.
After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.
- Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
