Railing Anatomy
Click on the hot spots below to explore the core components of a railing system.
Railing post
A railing post is a vertical support that secures the rails in place. Choose from various styles to suit your design, from modern to traditional. Our durable posts offer both strength and style, enhancing your outdoor space with lasting beauty and safety.
Top Rail
A top rail is the horizontal part of a railing that provides support and frames your railing with timeless appeal. Choose from a simple aluminum rail or upgrade to a cocktail rail for a stylish, functional entertaining space.
Bottom Rail
A bottom rail forms the foundation of your railing system, supporting the infill securely. Built for durability and style, it ensures a balanced and cohesive design.
Aluminum Balusters
A baluster is a vertical post that supports the top rail and adds structure to your railing system. Choose from square or round aluminum balusters for a modern, durable design that enhances both the style and security of your outdoor space.
Glass Infill
A glass infill features clear panels that provide an unobstructed view. Perfect for preserving sightlines and enhancing illumination, it adds a touch of elegance to any setting.
Mesh Infill
A mesh infill combines a unique pattern with structural integrity to create a secure barrier. Its industrial style adds texture and intrigue while allowing for airflow and visibility.
Rod Rail Infill
Our rod rail infill features slim, horizontal rods that emphasize clean, modern lines. Sleek and functional, it creates a streamlined aesthetic perfect for minimalist designs.
