The price of Trex composite decking differs based on the grade of the company's three offerings. The wood-alternative planks come in the lowest-cost Trex Select, moderately-priced Trex Enhance and the most expensive Trex Transcend varieties.
Trex Select planks, rated as a good selection by the company website, come in five colors. The decking, similar to other plank products offered by the company, has a 95 percent composition of recycled materials, such as sawdust, wood and plastic.
The Trex Enhance series of decking receives a better rating by the company than Select planks and comes in three natural wood colors. The Enhance line of planks features Trex hideaway hidden fasteners to avoid visible screws. It is mold and mildew resistant and pairs with a variety of railing systems also offered by the company.
With the Trex Transcend line of composite decking, the consumer chooses from 10 natural wood colors in three categories, classic earth tones, premium tropicals and porch colors, as of 2015. This line of planks receives the best rating from the company, and it features a superior resistance to damage, fading, staining and mold.
Other companies, such as Veranda and TimberTech, offer competing varieties of composite wood-alternative decking, as well.
