soft annealed 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.

In addition, many luxury cat cage, dog cage, parrot cage, bird cage and flock bird cage, will use iron square tube. Luxury cage using iron square tube is generally as a cage body frame, and then on each side of the welded iron wire. Square tube cage is characterized by more beautiful shape design, cage body more solid, more surface treatment methods.

Now most people buy barbed rope choose blade barbed rope, why is this? The blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet to punch out sharp knife sheets. The high tension galvanized steel wire or blade barbed wire is made of stainless steel wire as the core wire. Because the gill net shape is not easy to contact, so it can reach excellent protection barrier effect. The primary raw materials of the product are galvanized sheet and stainless steel plate.

The common type of barbed rope is double-strand barbed rope, and the models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm, and all of them are galvanized barbed rope (plastic coated barbed rope is rarely used). The barbed distance (that is, the distance between winding wires) is generally 14 cm. Here’s what these models mean:

1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.
