Trex Deck Framing – Does Trex Offer Rot Resistant Deck Framing?

A common question among homeowners and deck builders is whether Trex manufactures a composite deck framing system that resists rot, like their composite deck boards. The short answer is no; Trex does not currently offer structural composite deck framing.

Most homeowners building a Trex composite deck use traditional pressure-treated lumber for the framing. While pressure-treated wood is commonly used for deck frames, it does have a downside: it can still be susceptible to rot, especially in harsh environments.

However, Trex once offered an alternative to traditional wood framing: a steel framing system called Trex Elevations. Steel framing is inherently more durable than pressure-treated lumber, resisting rot, warping, and other issues that wood can develop over time.

Trex Elevations steel deck framing was highly regarded for its longevity and resilience. But Trex no longer manufactures this product; they sold this division, and it’s now produced and distributed by New Castle Steel.

Benefits of Steel Deck Framing for Composite Decks

Using steel framing with a composite deck like Trex provides several advantages:

  1. Longevity: Steel framing will outlast pressure-treated wood by a significant margin, providing a longer lifespan for your deck’s structural support.
  2. Structural Integrity: Steel framing is less prone to warping, twisting, and sagging, issues that can impact the stability and appearance of wood framing.
  3. Corrosion Resistance: New Castle Steel’s triple-coated galvanized steel is highly resistant to corrosion, making it ideal for regions with high humidity or moisture exposure.
  4. Compatibility with Composite Decking: Steel framing complements the long-lasting, low-maintenance benefits of composite deck boards, creating a complete decking solution that’s durable from the ground up.
