* Stainless Steel: HCS01,HCS03 etc.
By working closely with customers in choosing optional materials, we can minimize wear and tear and associated costs.
3. Raw material guarantee
The company has been cooperating with domestic and foreign first-line brand material suppliers for a long time, and has a strict quality control and performs regular audits and inspection of the factory (elemental analysis, metallographic analysis, ultrasonic flaw detection, etc.) to ensure a 100% qualified status.
4. Heat treatment
heat treatment is very important in the screw production process. In order to ensure the quality of products, Joiner has purchased professional heat treatment equipment to produce, so that we can control the construction process by ourselves. In China, we are the only company that does heat treatment by ourselves, and the heat treatment of screw components made by Nanjing factory is processed by outsiders, so the quality of products can not be completely guarantee.
