There are three common methods of Stay Wire Assembly Fititngs surface treatment process:
1. Electro-galvanized
Electro-galvanizing is the most commonly used surface treatment method for Screws Stay Wire Assembly Fititngs. Not only is the cost low, the appearance of the Stay Wire Assembly Fititngs, which are often galvanized, is also more beautiful, and can be electroplated into black or army green.
2.Screw Stay Wire Assembly Fititngs surface phosphating
The surface phosphating of the Screw Stay Wire Assembly Fititngs is cheaper than galvanizing, but its corrosion resistance is worse than that of galvanizing. The Stay Wire Assembly Fititngs of the screw should be oiled after phosphating, because of its corrosion resistance and the performance of the oil applied. There are many big relationships.
Most of the Stay Wire Assembly Fititngs used in industry are phosphated and oiled because of its consistent performance of torque and pre-tightening force. In the assembly of parts, it is guaranteed to meet the tightening requirements expected during the design, so it is used more in industrial construction.
3. Oxidation (blackening)
Screw Stay Wire Assembly Fititngs blackening + oiling is a very common coating for industrial Stay Wire Assembly Fititngs. Because it is very cheap, it is cheaper than all surface treatments. And it looks good before the oil runs out, but the blackened Stay Wire Assembly Fititngs surface treatment basically has no anti-rust ability, so it will quickly rust if you don’t apply oil, even in the state of oil, its salt The fog test can only reach 3-5 hours.
The above is the relevant knowledge about the surface treatment process of Stay Wire Assembly Fititngs, I hope to give you a reference when using Stay Wire Assembly Fititngs.
