Frequently Asked Questions
Trex Fencing offers superior durability and performance that you can’t get from wood. Trex Fencing resists termites, won’t rot, warp, or splinter and never needs staining or painting. What’s more, Trex Fencing is made from 95% recycled materials (reclaimed wood as well as recycled plastic), making it an environmentally-friendly choice you can feel pleased about.
Understanding the differences between a stockade composite fence and an innovative high-performance Trex fence is an important factor in distinguishing the benefits of Trex.
Stockade Composite Fences (Dog-Eared). These traditional types of fences use backer rails and pickets screwed or nailed to the rails. Fasteners are visible on these types of fences. True privacy is hard to obtain because the expansion of the material at higher temperatures requires the pickets to be gaped during installation. The gap becomes even more pronounced when the temperatures drop and the material contracts. A board-on-board (overlapping picket) design could be used, but that creates additional expense and still won’t fully close gaps if the boards warp. Since backer rails are usually exposed on one side of the fence, determining which side will face the neighbors could lead to difficult conversations. The typical recommendation for stockade-style fences is to install them on 6′ post centers, which adds costs for posts and causes extra time and expense for labor. Stockade composite fences are usually not tested or backed with product engineering.
Innovative High-Performance Trex Fencing. The innovative design of Trex Fencing includes a board-on-board appearance with top and bottom fascia rails, capped with an attractive shadow-line. The fence’s innovation isn’t just about appearance — it is easy for do-it-yourselfers or professionals to install. The form and function of the components were also carefully considered during development. For example, the brackets allow fasteners to be hidden; also, the interlocking picket system provides complete privacy and eliminates warping while strengthening the fence. Trex Fencing is installed on 8’ post centers reducing additional product cost and extra time for labor.
With wood fences, maintenance costs add up over time. Although Trex Fencing costs more initially, you’ll never have to sand, stain or paint your Trex Fence. Over the life of your fence, those reduced maintenance costs add up to a greater value than wood – not to mention the value of all the time you get to spend enjoying your fence rather than working on it.
While most of the raw materials used in making Trex Fencing are recycled, these materials are carefully processed to ensure the highest level of quality and performance. The end result is fencing that performs better than wood, actually lowering your cost over time through less maintenance. To learn more, please review our eco-friendly page.
The Trex environmentally-friendly manufacturing process recycles factory refuse/runoff back into the manufacturing line. Within the manufacturing plants, the trailers that carry product run on vegetable-based oil hydraulics. Trex is a member of the USGBC (U.S. Green Building Council) and Trex products contribute to LEED (Leadership in Energy and Environmental Design) points. Review our eco-friendly page for more information.
Trex Fencing is made from 95% recycled materials, including reclaimed wood and sawdust as well as recycled plastic from many common household items, such as the plastic wrap on packaging for paper towels and toilet paper, dry cleaner bags, newspaper bags, grocery and shopping bags. Trex annually keeps more than 400 million pounds of plastic and wood scrap out of landfills. That makes Trex one of the largest plastic film recyclers in the U.S. In fact, 100′ of Trex Fencing contains about 120,000 recycled plastic bags.
Yes. The weathering process is completely natural and doesn’t negatively impact the product. Typically, several weeks after installation, Trex Fencing will fade to a lighter color.
Natural Weathering. The Trex product receives heavy pigmentation during manufacturing to allow it to settle into a lighter shade when weathered. Under normal conditions, twelve to sixteen weeks of exposure to sunlight and rain are typically required for Trex to achieve its weathered color. This process is completely harmless to Trex products and does not affect the durability. The post caps and top rail will fade the fastest because of their direct exposure to the elements. Due to their vertical orientation, the pickets and post faces may take considerably longer to fade. The “after-weathering” color of Trex may be different from the colors shown on the Trex Colors page.
Color Variation. Due to the nature of composite materials, it should be expected that color variation between individual components may occur and, in some cases, may be significant. Trex Fencing is produced from a variety of recycled plastics and wood fibers, which absorb pigments differently. While all colors of Trex Fencing may contain variation, it is typically more pronounced with Saddle and Winchester Grey. The three colors of Trex Fencing will lighten over time and color variation may become less noticeable. However, weathering will not eliminate all variation. Where possible, extra care should be taken to install similarly pigmented pickets in a section to minimize the appearance of variation. Color variation and fading do not affect the integrity of the product and are not covered under the Trex Warranty.
Trex Fencing can handle any climate: hot, cold, humid, or dry. The unique formula of Trex makes it a durable, long-lasting outdoor building material.
All composite material will expand and contract with changes in temperature. If properly installed, Trex components are manufactured in a manner to accommodate these fluctuations. Gate hardware is also easily adjustable and may require some fine-tuning as temperatures change.
Initially, Trex Fencing does cost more than wood and vinyl (PVC) fences; however, there is little, if any, maintenance costs. Additional maintenance expenses can make other fence systems cost more than Trex Fencing over time. Of course, the real value is enjoying your yard secured by Trex Fencing without spending time and money on maintenance.

The Trex post is hollow and can slide over a support embedded in the wall. To ensure that the placement will not fail, it is important to evaluate whether or not the slab or wall is sturdy enough to support the fence.
It’s not recommended to attach Trex Fencing posts to a concrete surface/slab; however, if it needs to be, we have z-shaped concrete posts mounts for fences 6’ and under, and heavy-duty concrete posts mounts for taller than 6’. It is best to core drill at least 30” to put a Trex post into the ground.
When mounting on a concrete wall it is important to evaluate the amount of sheer force that will be applied on each post. If you are in a high wind zone or the post will have a gate swinging on it we recommend that the post is embedded in the concrete or is slid over a steel post that is embedded. The best way to install a fence on a retaining wall is to embed a steel post (a 2-3/8″ Schedule #20 galvanized steel post or a heavy-duty post stiffener) directly into the wall and slide the Trex post over it. If using a 2 3/8 post fill the post with concrete to stiffen it. For ease, attach the brackets before pouring concrete into the post.
If a Trex Fencing post needs to be placed on a concrete surface or slab, it is important to evaluate the amount of sheer force that will be applied on each post as well as the quality of the concrete to be mounted on. If you are in a high wind zone or the post will have a gate swinging on it we recommend that the post is embedded in the concrete or the concrete is cut so that the post can be embedded directly in the ground 30” min. post depth.
Just like lumber, Trex Fencing materials can be cut to any length or height. Suggested blade type: carbide tip metal. Recommended power tools to cut materials: skill saw and miter saw.
Trex Fencing can be angled with angle adaptors. The angle adaptor attaches to the standard fence bracket for a 22.5-degree angle. When doubling the angle adaptors on the back of the fence bracket, this allows a 45-degree angle. Refer to the Trex Fencing Installation Guide.
Trex wood plastic composites are not structural and should only be used for intended design.
Trex Fencing, when properly installed for approved applications, is code compliant. Trex Fencing has been used on numerous residential, commercial, and government projects with heights ranging from 3’ to 12’ tall. As always, check with your local codes for approved heights. Trex Fencing engineering documents are available under Resources/Technical-data.
