13 Stunning Trex Deck Railing Ideas: Elevate Your Outdoor Space with Style

When designing your outdoor space, Trex deck railings offer a wide range of options that not only provide safety but also enhance the aesthetic of your deck. 

From sleek aluminum designs to contemporary glass railings, there’s a perfect match for every style. Below, we’ll explore various Trex deck railing design ideas that combine function, style, and durability, all available through Lumber Plus.

Deck Railing Infill Options

Infill refers to the material or structure that fills the space between the top rail and the bottom rail (or the deck floor) of a railing system. It’s the primary component that provides safety, keeping people from falling off the deck, while also playing a major role in the overall design. 

Different types of infill can drastically change the look and feel of your deck, whether you’re going for a sleek, modern design or a more traditional aesthetic.

Here are four popular types of Trex deck railing infill:

Aluminum Railing

Aluminum railing infill offers a lightweight, durable, and low-maintenance option. It’s perfect for those who prefer a sleek, minimalist look, as the slim aluminum bars provide safety without obstructing views. Lumber Plus carries a variety of Trex aluminum railing options, making it easy to create a modern and durable deck.

Mesh Railing

Mesh infill brings an industrial, contemporary edge to your deck. Typically made from stainless steel or powder-coated metal, mesh panels create a visually interesting texture while offering strength and safety. Trex mesh railing infill is ideal for homeowners looking to add a bold, distinctive feature to their outdoor space.

Glass Railing

Glass railing infill is the perfect choice for homeowners who want unobstructed views of their surroundings. The clear panels maintain the open feel of your deck while offering the protection of a solid barrier. Whether you’re overlooking a scenic landscape or a beautiful pool, glass railings allow you to enjoy the full beauty of your outdoor space. 

Rod Rail

Rod rail infill is a sleek, modern option that uses horizontal rods instead of vertical balusters. This design is perfect for minimalist, contemporary decks, as the slim horizontal lines create a clean, open look. Trex rod railing is a great option for homeowners who want something a little different from traditional railing styles.
