The hot-dip galvanized cable bridge is made of cold-rolled steel plate, and the surface technology is hot-dip galvanized. It consists of trough, tray or stepped straight line sections, bends, tees, four-way assemblies, and supporting arms (arm type brackets) Hangers, etc. form the full name of a rigid structural system with tightly supported cables.
The hot-dip zinc layer is formed by zinc in a high temperature liquid state in three steps:
1. The iron-based surface is dissolved by the zinc solution to form a zinc-iron alloy phase layer.
2. The zinc ions in the alloy layer further diffuse to the matrix to form a zinc-iron miscible layer.
3. The surface of the alloy layer is surrounded by a zinc layer.
Advantages of hot-dip zinc cable bridge: It has very good anti-corrosion performance, long durability, long life than ordinary bridge, high degree of industrialization of production, and stable quality. Therefore, it is widely used in outdoor environments that are severely corroded by the atmosphere and difficult to maintain.
With the development of industry and agriculture, the application of hot-dip zinc cable bridges has also expanded accordingly. Therefore, hot-dip galvanized products are used in industries (such as chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, etc.), agriculture (such as sprinkler irrigation, housing, etc.), and construction (such as water and gas transmission, and wire sets Pipe, scaffolding, houses, etc.), bridges, transportation, etc., have been widely used in recent years. As hot-dip galvanized products have the characteristics of beautiful appearance and good corrosion resistance, their applications are becoming wider and wider.
