The smaller the type of RDS coating rod, the more gray and black it feels ("oxidized?") visually. In fact, it is not the case. We randomly checked three batches of coating rods in the Beichao warehouse, and compared domestic coating rods and Japanese OSP , RK should have done spot checks and comparisons, and the answers are announced as follows:
1. For small RDS coating rods (such as #3 #5 #6 #8), the finer the steel wire, the more gray and black it will be when visually inspected. The same phenomenon is also true for RK thin rods, regardless of batch or storage time;
2. Unlike some domestic products, the surface plating of RDS looks very beautiful. The main pursuit of RDS coating rods is precision.
3. From an optical point of view, the thinner the wire, the smaller the reflection on the surface, the more grooves, and the more groove shadows formed, the darker it looks, and the appearance will be different due to the stainless steel material and different light scenes. Feels gray or "oxidized".
4. From the perspective of aging, the main rod and the winding wire are actually the same material. If the steel wire is oxidized, the main rod should also be oxidized. RDS has existed in CHINA for more than 30 years, and so far no such problems have occurred.
5. Due to the shooting technology, market personnel tend to choose a larger size for shooting (easy to shoot clear steel wires), so the pictures presented on the North and South Tide will look brighter. Customers don't need to worry about quality issues.
