【Spring Electroplating Instructions】

This product's springs are made using chrome plating technology (all Double Forest springs are chrome plated), ensuring long-lasting use without rusting or deforming. Of course, this type of plating has a higher cost, but many businesses use zinc plating, which is cheaper. However, the springs are prone to deformation and corrosion, and the diameter of the springs and the wire diameter of this model are much larger than those of the average. You won't know until you try it, and once you do, you'll be surprised. You can buy it and compare it with others! The service life of this model is absolutely more than three times that of the average three-in-one pull-up machine!
