Is there a scar on the car hub that can be repaired? What kind of wheel hub quality is guaranteed?

First of all, there are several types of wheels, including iron wheels and steel wheels. Now the latter, commonly known as steel ring, is widely used, and steel ring is divided into painted steel ring and brushed steel ring. Of course, these can be repaired. If it's a spray-painted steel ring, it can be touched up. Generally, a steel ring is several hundred pieces, and the effect of spraying varnish after completion is the same as that of new one.

Drawing steel rings is different. Its repair process is to remove a layer on the outside of the hub by machine, so why is it called brushed steel ring, and it will become thinner and thinner? If the damage is not serious, it will be fine after drawing. If the damage is relatively large, maintenance is not recommended. I don't need to say what hidden dangers there will be if the steel ring is thin. Therefore, it is relatively reliable and has quality assurance. It is suggested to seriously repair the steel ring, especially the drawn steel ring.

How to tell whether it is a painted steel ring or a brushed steel ring?

The surface of the painted steel ring is uneven and one side is irregular, as shown above.

The surface of the brushed steel ring is flat and feels like a small notch by hand, as shown in the figure below.

The paint surface of the wheel hub is painted, painted, electroplated and sprayed.

Ordinary car body panel repair and painting shops can do it, and the price is not very high, so the shop will earn some manual money.

Painting is not a problem now. You can find a few in general cities, that is, turn the wheel hub surface out to reveal the original color of aluminum alloy, and then spray transparent paint to prevent oxidation and rust. The price is not very expensive, it is more cost-effective than buying new wheels.

Electroplating and spraying are relatively expensive. Because of pollution, there are not many big cities and the prices are high. I changed the cheap wheels directly, which was too much trouble.

If the wheel hub is cracked and deformed, it can also be repaired, but it can't be too serious. These problems should be dealt with in professional tire shops. The cracked hub is welded with aluminum, so it is generally not easy to crack again. The deformed hub is simple. After heating, just tap it with a hammer. It's just that the hub is not round as a whole, so it can be used directly after it is finished.
