Before the steel shield is delivered, we will apply a layer of oil to the surface of the steel shield. Some customers have said that this layer of oil is used. Of course, this layer of oil is not made for the sake of the steel shield. It is mainly to maintain the effect of the steel shield in the later use. Today, we talk about the reason why the steel shield is coated with oil before leaving the factory.

The steel shield is shipped with a layer of oil on the surface. This layer of oil is a lubricant. This layer of oil plays a vital role in the longevity of its use, not for the glare of its surface. This layer of oil allows the steel shield to maintain the necessary lubrication, reducing the possibility of rusting; The steel shield protects against friction during operation; this layer of oil also retains its internal strips to reduce unnecessary damage and reduce wear.

In the later period of customer use, we recommend that users often brush or oil their maintenance, this link can really protect and extend the life of the steel shield, but if the customer will almost never do it in the later use, even if Some customers will do it, but they are not perfect during the period.

This kind of maintenance of the steel shield is still relatively weak. Many customers feel that the steel shield is not a valuable component. If it is not bad, it will be replaced with a new one. In fact, this view is a big mistake.
