Before painting, the fences must be sand-blasted and cleaned three times: water cleaning-- park rising-- water cleaning. The powders we use are Dupont or Aksu which are internationally famous brands, to ensure the plastic layer is beautiful, firm, and smooth, and the surface is resistant to ultraviolet and corrosion.

First of all, we don't allow any defective products to leave our factory. We do strict quality inspections at every step and guarantee to reduce the defective rate to less than 0.1%. But if there is any problem, we will guarantee to solve it within 2 working days after your pictures or video proof.

We can supply the sample if we have ready parts in stock, but the customers have to pay the courier cost. And all the sample costs will be refunded after you place the order.

Our product can last for 10 years at least. Usually, we will provide a 5-10 years guarantee.
