As we all know, stainless steel barbed rope is installed in the outdoor, after a long time of exposure to the sun is easy to rust, once rust service life will end. So want to extend the service life of stainless steel barbed rope must prevent rust. In general, in order to prevent rust, we will choose to spray stainless steel barbed rope.

The size of the dog cage is generally relatively small, suitable for indoor small dogs, dog cage is easy to carry, go out to compare the use, folding dog cage high strength steel wire and steel pipe material, the outer layer spray treatment. Strong texture, excellent rust resistance, the dog cage inside the tray, can be pulled out, convenient to clean the dog’s urine and feces, folding, dog cage is suitable for families and pet stores to raise more pet dogs.

Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.

If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.
