Bridge protection system generally do not need to install special drainage system, the use of hexagonal mesh gabion cage, the filling is selected stones, the stones are not easy to wear, and between the stones and stones will retain some space, so it is very good to meet the drainage requirements.

Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.

Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.

When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.

The silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.

We basically know that the barbed wire fence generally has two kinds of ring and linear filamentous, the overall protective wire mesh selection of galvanized, stainless steel processing raw materials, long-term use is not easy to rust. Barbed wire fence uses stainless steel barbed wire, plastic coated barbed wire, aluminum coated barbed wire, galvanized barbed wire and other raw materials through special wire drawing into the strand planning, has a strong role in protection and maintenance. Widely used on both sides of the highway, grassland, gardens and other places, because it is a field protection product and therefore updated faster, so how to use the barbed wire fence after abandonment? Here are some of the uses of discarded blades.

There is also a straight blade stabbing rope, which is mainly because the board and wire are not wound in the process of wrapping, so the blade stabbing rope produced is a straight product. The length of the barbed rope of this specification cannot be too long due to the limitation of logistics, and it cannot be bent because it is easy to be deformed by force. This is also the main reason why the barbed rope of the straight blade is not whole or long. Customers are advised to determine the spacing before purchase to prevent losses caused by no calculation.
