[Spring Plating instructions]]

the spring of this product adopts chrome plating technology (all Sunlin springs are chrome plated), which is used for a long time without rust or deformation. Of course, the cost of this electroplating is relatively high. However, many merchants use galvanized, the cost is low, the spring is easy to be deformed and rusted, and the spring diameter and steel wire diameter of this chest expander are much larger than the average. Don't have to know, I'm scared when using it, you can buy it and compare it! The service life of this model chest expander is definitely more than 3 times that of the general three-use chest expander!
