As a member of the auto parts market, the sheet metal parts can not be left alone. There are many "secrets" that are not known to consumers.

The sheet metal parts of automobiles, generally refers to the metal shell of automobiles, which is usually made of steel plates. On the basis of ensuring a certain strength, it is the basic requirement to minimize the weight. In addition to its protective and aesthetic functions, automotive sheet metal parts are also the main carriers of gas resistance for automobiles. Therefore, the quality and life of automobile sheet metal parts not only affect the appearance of the car, but also increase the resistance of air to the car due to the quality and deformation, which makes the economy decline.

According to the manufacturer, automobile sheet metal parts can be divided into two categories: original parts and auxiliary parts. The so-called "original factory" generally refers to the loading parts for the whole vehicle factory, while the "auxiliary factory" is the non-supporting parts produced by the non-supporting manufacturers. The price of most of the original parts is higher than that of the subsidiary parts. It is generally believed that the original parts replaced at the special maintenance station or bought in the auto parts market should be the same as the original car, in fact, there will be a big or small difference. For example, the "original factory" type sheet metal parts can be divided into several levels: first-class quality is good, it is specially loaded parts, that is, the original belt, which can not be bought outside; second-class products are supplied to special maintenance stations, except for the gap in installation or replacement process, the product itself is not much different from the first-class; third-class is the accessories production flowing to the retail market. Although the price of the original parts is still higher, the quality of the products can't be compared with that of the original cars.

The quality of the products of the "sub factory" is equally good and bad: the products of the "sub factory" automobile sheet metal parts of the first class are almost comparable to those of the original parts. This kind of products are mostly from the manufacturers with strong capital and hardware, and can be standardized from material selection to assembly line mechanical operation. The two level "sub factory" parts, materials and manufacturing processes are all inferior to the first grade products; and the latter category. It is abusive, no quality at all, only rely on low prices to deceive consumers. Some maintenance stations operate in violation of regulations. Their so-called original parts are actually inferior "by-products" wholesaled from the auto parts market. In order to make huge profits, when they sell to the owners, they will carry the banner of "original factory", and their prices will naturally be much higher than those in the auto parts market.
