We often use junction boxes in our daily production and life. There are many types of junction boxes, and the materials of junction boxes are also different. There are plastic junction boxes and metal junction boxes. Each material of junction box has different usage scenarios. Let's learn about the differences between metal junction boxes and plastic junction boxes.

  First point: When choosing things, we must pay attention to their cost-effectiveness, which includes price and service life. These two points are also what we value when buying things. Everyone knows that junction boxes are used on walls and may be buried in the walls for 20 to 30 years without moving. Therefore, the corrosion resistance of junction boxes is very important. Plastic junction boxes are more practical in this regard and will not corrode and rot for many years. However, metal junction boxes are more prone to corrosion. If the room is humid or during the damp season, they are easily affected by moisture and will be corroded within two to three years. Therefore, from the perspective of service life, plastic junction boxes are better.

  Second point: It is the cost. Metal junction boxes are relatively expensive. The price of metal junction boxes and plastic junction boxes of the same size will differ by one-third. If used in large quantities, the price difference will be quite significant. This point also needs to be considered.
