U-PVC products can be produced in any color and can be produced without any impact on the quality of the product. But in the national standard of Iran, the suggested colors include:
white
cream
Gray
They say that the most common color in Iran is gray.
The important thing about the color of U-PVC pipes and fittings is that the color of pipes and fittings cannot show and determine the quality or poor quality of the pipe. This means that the lighter pipe does not indicate that the quality of the material is high and new, and the darker pipe is not a reason for recycling or poor quality of the pipes.
