The Surface Treatment of Screw
Products Category : Construction screw
Applications
Surface treatment technology, for the surface burning chips and into a skin film layer, three layers of superior anti-
corrosion technology.
Class coating process
Both Class process and Ruspert coating areAustralian AS3566 standard raw materials, thedifference between Class and Ruspert is that theclass surfaces made of one more layer of curingclosed protective coating, which will notbedamaged during use to achieve better anti-corrosion effect.
Environmental protection | Products comply with EU ROHS environmental protection level 4 standards. |
High corrosion resistance | Salt spray resistance ( Salt spray test: 2000H ) , 25 acid rain cycles, weather resistance. |
The composite film | Because of the use of three layers of anticorrosive composite membrane, the damaged area has good corrosion resistance. |
Resistance to corrosion | Reduce corrosivity in contact with heterogeneous metals. |
Low temperature treatment | The processing temperature is below 200 degrees, so it will not affect the physical properties of the product. |
Variety of colors | Color can be mixed as required. |
Service reliability | The surface is oily, small wear when using, salt mist will follow a litle drop, the effect of corrosion is minimal. |
Bi-metal | The 300 series Austenitic stainless steel composite screws SUS304+SCM435 ( 304-A2 ) and SUS316+SCM435(316-A4) with anticorrosive coating. |
