Ordinary installation of blade thorn rope on the wall and the height of the wall in two meters up and down the general construction costs in a dozen yuan a meter, but if it is said that the height of the prison construction ordinary wall has reached four or five meters so that the construction cost of each meter is about 30 or 40 yuan, mainly because of high altitude operation risk degree is relatively large reason. The construction cost is different, but the price of blade thorn rope is the same, often the construction cost is higher than the product, which is the thorn rope factory recommends customers to use better quality blade thorn rope, which eliminates the cumbersome time and cost of subsequent demolition and installation.

The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
