When asked for a price difference for low grade, medium grade, and high grade quality composite materials you would expect to get 3 different quotes. Sadly there really isn’t much difference in them. The materials they are made with are different, although most all the products are offering the same warranty period for them. If they want to sell and stay in business they have to offer about the same warranty. The difference in price comparison comes from popular choices. Different manufactures offer different color shades based on their prior sales, or anticipated ideas of what is gonna sell. As some fade out and don’t sell well they phase those colors out and discontinue them. So often the manufacture I use to supply composite decking is based on a color choice by the customer. I like to have multiple brands to try and get you the color or close to the color you are wanting.
