HDG Hot Dip Galvanized Flat Steel Marine Cable Ladder 75mm Width

Marine Cable Ladder Flat Steel Hot-Dip Galvanized Cable Ladder System Used For Ship

The purchase of marine cable bridges must pay attention to the following issues:

One, the choice of structure type. In some engineering design instructions most of the time just a simple general cable bridge called "bridge", in fact, there are many different kinds of detailed divisions, different types, different structural characteristics, different production materials, the price is different, and even a far difference. Experts say that the confusion of the type of structure will lead to poor heat dissipation in the working environment and the difficulty of mechanical protection work, etc. So in the purchase of marine cable bridges must be the correct structural characteristics, so that the design staff to be in the materials table and the identification of the plan must be clear and understandable to point out to the.

Second, according to the material to choose from. Cable bridge material has many kinds. According to different division methods and have a variety of different types, currently, in the purchase, most of them are based on the material to divide. There are several: glass steel, steel and aluminum alloy so on three. Among these three, FRP is the lightest in quality, corrosion resistance and water resistance are better than the remaining two, so it is more suitable in the chemical industry. And the service life of FRP is relatively long, generally about twenty years. The problem is that the price is also relatively expensive, from the current market price, it is about three times that of steel. However, due to its superior construction performance, it is still welcomed by most consumers. As for the aluminum alloy cable tray, the cost is higher than steel, while the life is five times that of steel, is also a more widely used product.

The basic construction material of the bridge is metal, but directly placed in the natural environment and without any protective layer, the metal is easy to chemically reactions with the water and air in nature, resulting in rust and corrosion, thus affecting the overall sturdiness of the bridge. Common types of bridges with a protective layer of hot-dip galvanized bridges and galvanized bridges, so the differences between these two types of bridges are also reflected in what aspects?

1, the production process is different: hot-dip galvanized steel or castings immersed in molten zinc in its surface to form a zinc-iron alloy or zinc and zinc-iron alloy cover, to obtain a protective layer, while electro-galvanization will be put into the electroplating solution after chemical cleaning of the steel surface, direct current one pole connected to the steel, one pole connected to the zinc plate placed in the electroplating solution, through the electrode reaction to getting the zinc layer.
2, anti-corrosion performance is different: electro-galvanizing is not very effective in preventing rust, because when the zinc layer is obtained in the electrolytic reaction, the galvanization is not uniform, and the amount of galvanization does not reach enough, and rusting usually occurs in two or three years; hot-dip galvanizing has a thicker coating and strong corrosion resistance.
