If you’re dreaming of adding some elegant curves to your deck design, you might be considering bending Trex composite deck boards. Whether you’re aiming for a unique railing, a rounded edge, or a striking inlay, curved boards can elevate your outdoor space from standard to standout. But how much does it actually cost to bend a 12-foot Trex board?

Let’s break it down.

Cost of the Board Itself

Before you even begin bending, you’ll need the board. Trex offers several product lines—like Enhance, Select, and Transcend—with Transcend being the most commonly used for curved applications due to its durability and flexibility when heated.

• 12-foot Trex Board Price:
  Expect to pay between $60 and $90, depending on the line, color, and supplier.

Cost of Bending a Trex Board

Bending a composite board isn’t as simple as flexing it by hand. Trex boards need to be heated to around 220–240°F to become pliable without cracking. This requires special equipment and expertise, so you have two main options: DIY or professional services.

1. Professional Bending Services

Many contractors or deck specialists offer heat bending services. Prices can vary depending on your location and the complexity of the bend.

• Typical bending service cost:
  $100–$300 per bend, depending on:
  • The radius and shape of the curve
  • The number of boards
  • Local labor rates
  • Turnaround time

Hiring a pro ensures accuracy and avoids the risks of damaging expensive materials during the process.

2. DIY Bending

For the brave DIYer, it is possible to build your own bending setup using heating blankets, custom-made ovens, or insulated boxes with propane heaters. While it’s cheaper upfront, it requires:

• Space
• Safety precautions (composite boards can off-gas)
• Time and patience

DIY cost estimate:
Building a custom bending setup might run you $200–$600, depending on the materials and tools you already have.

Alternatively, companies like Schultz Forming Products sell dedicated composite board ovens starting around $4,490 if you plan on making a lot of bends for larger-scale projects.

Final Thoughts

Curved Trex boards can truly make a deck stand out, adding visual flow and architectural interest. While it’s a bit more expensive than standard installation, the result is often well worth the investment—especially when done right.

If you’re only bending a few boards, hiring a professional is typically the most cost-effective and stress-free option. However, for larger projects or frequent bending needs, investing in your own equipment may make sense in the long run.
