Lamp posts: why do you want to hot dip galvanized?

- -

as countries to speed up the pace of urbanization, the king of road lighting demand more and more, its form a complete set of light pole market is becoming more and more big. But do you know? Light pole points, hot dip galvanized and cold galvanizing process? Why light pole manufacturer galvanizing instead of cold galvanizing. The following lighting lamp posts gave you talk about why hot dip galvanized.

a, what is hot dip galvanized, hot dip galvanized advantages?

also called hot dip galvanizing zinc and hot galvanizing, is an effective way of metal corrosion, mainly used for metal structure industry facilities. Is after rust removal of steel into the liquid zinc melting ℃ or so, the zinc layer adhered on the surface of the steel members, which have the purpose of corrosion. Hot galvanizing process: finished pickling - Water - Add - plating solution Dry - Plating - Cooling - Medicine - Cleaning - Polished - Hot dip galvanized finish.

galvanized anti-corrosion performance than cold galvanizing: when the zinc layer destroyed, endanger the iron matrix, the zinc electrochemical protection on the substrate, the standard potential of zinc - 。 V, standard potential - of iron 。 V, zinc and iron to form the micro battery zinc as the anode is dissolved, iron are protected as the cathode. So light pole galvanizing on substrate metal atmospheric corrosion resistance is superior to electric galvanized iron.

2, what is the cold galvanized, what is its advantage?

cold galvanizing, also called electricity galvanized, is the use of electrolytic equipment the workpiece after degreasing, pickling, in the composition of zinc salt solution and connect the cathode electrolytic equipment, placed in the workpiece on the opposite side of zinc plate connected to the anode electrolytic equipment, processing power, using the current from the positive to the negative directional movement, deposits a layer of zinc on the workpiece. Cold galvanized after light pole seem more smooth, bright.

however, pleasing appearance of cold galvanizing light pole antirust effect was only to years, and has a rough surface of hot dip galvanized lamp posts on the zinc layer is thicker than the cold galvanized lamp posts a few times, anti-corrosion performance is leading, hot dip galvanized lamp posts we light pole manufacturer warranty years at least will not rust, although the price on the hot dip galvanized lamp posts will be a bit more expensive than hot dip galvanized, but in the long run, than rust in hot dip galvanized or cold galvanizing popular, and street lamp is an important road construction project, the image of a place, if use cold galvanized lamp posts, two years later, the rust will greatly affect beautiful! So light pole to use hot dip galvanized.
