galvanized expanded metal mesh

Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

The barbed wire factory will store the blade barbed wire inventory in the appropriate place, because it understands the product characteristics.

The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.
