Composite and aluminium deck railing kits and systems

Trex offers a wide variety of decking options and railing configurations capable of being custom curved. When considering a deck with these characteristics, use the Find a Builder tool to determine which professionals in your area work on curved profiles. When planning curved railing, visit our Trex Signature® Curved Railing page for design and ordering guidance.

Note: Due to the unique composition of Trex Signature® decking we do not recommend heating and curving this product.

Each Trex deck rail kit includes installation instructions based on the product and application in which it is being used. In addition to our written instructions, you can see installation videos on our TheTrexCo YouTube channel

Trex decking is designed for a low-maintenance experience. A simple soap-and-water clean is all it takes. For more details, visit to our Care and Cleaning section.

Railings usually consist of a top and bottom rail, post, post sleeve, balusters, or an infill option like glass or mesh. 

Railing costs vary significantly based on details such as material, labour, and design extras (such as curving, cocktail rails and lighting). Use our Cost Calculator Tool to get an idea of what the railing may cost for your project.

The best railing for your deck is the one that suits your style and meets your practical requirements. For example, does the railing need to be a certain height for your local building code requirements? Do you prefer a more modern or traditional aesthetic?

With different levels of expertise, the easiest railing to install is our Signature Assembled Panels and Signature Posts with Premounted Brackets. This system consists of pre-assembled parts that save you time and labour costs, without compromising the structural integrity or beauty of the classic Signature design. Watch our Signature railing installation video to see the time savings the assembled panels bring to a project.
