General Guidelines

Always wear safety glasses & a respirator when cutting composite materials since a fine dust is often generated in the process.

High (spindle) speed, low (travel per time) feed. This is a good rule of thumb when cutting composites with traditional tooling (e.g., drilling, milling etc.)

What Do You Use To Cut Carbon Fiber?

FOR TUBING:

We use high-speed wet saws with diamond abrasive round saw blades.

You could also use a tile saw, abrasive metal cut off wheels, or dremel with diamond cut off wheel.

Do not use a hack saw.

FOR PLATES AND SANDWICH PANELS:

We use a waterjet or CNC mill with carbide tools or diamond abrasive tools. Or we do straight cuts on panel saws with a diamond coated saw blade, dry cut vacuum evacuation or a large tile saw wet with diamond abrasive saw.

You could use a tile saw, abrasive metal cut off wheels, or dremel with diamond cut off wheel.

Do not use a hack saw.

FOR HOLES:

We use carbide drill bits.

You could use any metal drill bits or carbide drill bits.

Do not use concrete bits.

TIP: When cutting, if you are getting chunks, increase the tools speed, and slow down how much you are cutting at a time. Seeing just dust is good!

With competitive price and timely delivery, Yuchen Dingsheng sincerely hope to be your supplier and partner.

For most materials we sell in their raw form (prior to cure, and or resin infusion), sharp scissors work very well. Electric shears will make short work of cutting dry materials. For aramids (e.g., Kevlar) we suggest you use finely serrated scissors.

Advantages Of Woven Fabric.

DRAPABILITY:

Some weaves will conform to compound curves better because of loose weaves and weave patterns. They also maintain adjacent fiber angles while conforming to complex shapes. (Unidirectional fibers are very difficult to conform to sharp inside and outside corner.) 2×2 twill is the most common for good drapability.

COSMETIC:

Some patterns just look better from a distance and are used to get that traditional carbon fiber look. Again, 2×2 twill is very common.

DURABILITY:

Woven fabrics resist edge fraying better than unidirectional fibers, especially when damaged. The woven tows will stop fraying as they pass under the perpendicular adjacent fibers. Some designers will place a single ply on the outside surface for durability and cosmetics.

THICKNESS BUILDUP:

Woven fabrics are thicker than unidirectional fibers, so they build thickness faster than unidirectional layups.

ISOTROPIC SIMPLICITY:

With each ply, you have an automatic isotropic layup with equal stiffness in two directions. (Isotropic: having a physical property which has the same value when measured in different directions.)

Disadvantages Of Woven Fabric.

PLY ORIENTATION:

With woven fabrics, there is always equal number of fibers running in one direction as is running in the perpendicular direction. This limits the customizable ply orientation by always including ply orientations in two directions for every ply.

FIBER CRIMPING:

As the fiber is woven, it passes over and under perpendicular fibers creating a slight bend in the fiber. As carbon fiber is strongest when it is straight, this crimping can cause a slight loss in bending stiffness. This is generally thought of as minimal, but in some structural applications, it can be a very important distinction.

RESIN CONTENT:



Woven fabrics will require a little more resin content to fill in all the gaps between the woven tows. Typically, it is about 5-10% more resin for woven fabrics. This can add weight and change the structural aspects of the part.

On average, the estimated material cost for a composite deck runs from $15 - $30 per square foot (including substructure, decking, hardware and fasteners).* We recommend using our online cost calculator tool and guide to get an estimate for your project's cost. For a true cost estimate, reach out to a Trex retailer or TrexPro deck builder.

*Average price range excludes Trex Signature® decking, our luxury decking collection. Trex actual material costs and install costs can and will vary based on geographic area, site location, seasonality, design complexity, whether the product is stocked locally, and additional features such as stairs, angles, curves, lighting, etc. For most professionally installed projects, materials constitute up to one third of the total cost

If you've noticed any staining, scratching or fading over the years, it's likely you have early-generation decking. While our early-generation decking was groundbreaking for its time, spills and scuffs can still leave a mark. Newer-generation decking is easy to spot because of its resilience. Today's Trex decks resist blemishes with an innovative, high-performance shell that wraps around three sides of our deck boards.

Early Generation Trex Decking
Early-generation composite decking (Trex Origins®, Trex Accents®, Trex Profiles®, Trex Brasilia® and Trex Contours®) represented a breakthrough for low-maintenance and durability. While wood decking inevitably suffered splinters, warping and rotting, and required considerable maintenance, early-generation Trex never had to be stained and did not rot, warp or twist like wood. Periodic cleanings with a composite deck cleaner were far easier than the dreaded sanding and staining required to maintain wood decks. As the category evolved, this early-generation composite was offered in additional colors and with grain patterns that reflected a more natural appearance. Even so, all early generation wood-plastic composites, whether Trex or a competitor's product, were not stain, scratch or mold-free, and did fade slightly in color as they naturally weathered. To address these issues, Trex introduced a new kind of high-performance decking in . As of , Trex no longer manufactures any early-generation composite decking.

Newer Generation Trex Decking
Newer generation Trex deck boards ( Trex Signature®, Trex Transcend® Lineage™, Trex Transcend®, Trex Enhance®, Trex Select®, Trex Contour®) are manufactured with a high-performance shell that wraps around three sides of the composite board to protect it from the elements, providing resistance to fading, staining, scratching and mold. In addition to improved performance, the shell technology offers:

- Easier maintenance: requiring only an occasional cleaning with soap and water or a pressure washer.
- Enhanced aesthetics: richer, long-lasting color palettes and natural wood grain patterns.
- Incremental warranty protection: 25-, 35-, and 50-year limited warranties for most products.

Trex materials come with specific warranties, but it doesn’t mean they won’t last longer. When Trex launched its original product in it came with a 10-year warranty. This product is still installed in many homes and looks great after more than 25 years.

There have been many improvements in our current products and our material now is a coextruded shell that protects the board from the weather, making them last even longer than our early materials.

Yes, a groove can be routed into a Trex decking board using the Trex Groove Cutter/Router, which can be purchased online. The Trex-branded router is specifically designed for creating grooves in Trex and other composite decking materials, ensuring a precise and clean cut for Hidden Fasteners. If you don't have access to the Trex- branded router, you can also use any 5/16” cut height carbide router bit with a ¼” shank, which is compatible for routing grooves into Trex boards.

Using the right tools, such as the Trex Groove Cutter or the recommended carbide router bit, ensures the groove is accurately milled without damaging the material. The groove will be perfectly sized for Trex's Hidden Fastener system, providing a sleek, fastener-free appearance on your deck. Whether using the Trex-branded router or a compatible bit, it's essential to follow proper cutting techniques to avoid overheating and ensure a clean, smooth finish. Always refer to the manufacturer's guidelines for optimal results when routing Trex decking.

When choosing fireplaces and fire pits, there are various options, each with distinct benefits and considerations. Here are our recommendations for safe installation on Trex decking:

For gas-burning fire pits/fireplaces, these are typically installed by cutting around the Trex decking, not directly on top of it. A fire-resistant material is placed underneath, and a protective stone wall or similar material is used to contain the fire and shield the decking from heat. Gas fireplaces should not be placed directly on Trex decking without proper protection. Propane tables are generally safe, as they don't produce downward heat. Trex Outdoor Furniture also offers propane tables to complement their furniture collections.

For wood-burning fire pits, these should not be placed directly on Trex decking unless a heat barrier is used. While we don’t have a specific recommendation for heat barriers, many are available on the market. It's important to note that Trex can soften at temperatures as low as 176°F, and the intense heat or embers from a wood-burning fire can damage the decking.

When it comes to adding a rug or mat to your Trex deck, we highly recommend selecting a product crafted from natural fibers and materials, such as jute, sisal, or bamboo. These options not only enhance the beauty of your outdoor space but also complement the durability of Trex decking beautifully.

It's important to exercise caution with rugs made from viscose material, as the dyes used can sometimes bleed, leading to potential staining that may be challenging to remove. Additionally, we advise being mindful of rugs made from plastic (polypropylene) or those with rubber backing, as they have the potential to draw out the colorant from the decking itself. This color loss can sometimes be irreversible, and we want to ensure your deck remains as stunning as it is functional.

Trex high-performance decking and railing products combine low-maintenance upkeep and design-minded style—all backed by our 25-, 35- and 50-year limited warranties. The protective shell technology means all of our deck boards resist staining, fading, and cracking, are resistant to scratching with Signature decking our most scratch-resistant board. Beyond that, Trex offers a variety of high-performance railing choices to meet different levels of style, performance and affordability.
