A Smarter Solution for Retro-Fit Decking

When working with an existing structure, traditional pedestal systems aren’t always an option. The Wallbarn Joist Hanger provides a secure and efficient solution, allowing the 100mm I-Plus Rail / Joist to be fixed directly to timber or steel substructures.

This eliminates the need for additional supports while maintaining the strength and stability required for decking installations. Designed for retro-fit and refurbishment projects, the Joist Hanger ensures a seamless connection, making it easier than ever to install decking over existing spans.

Designed & Engineered for Strength & Stability

Manufactured from galvanised steel, the Wallbarn Joist Hanger offers exceptional durability and resistance to corrosion, ensuring a long-lasting and secure fixing point. With a 61mm width, it perfectly accommodates the 60mmbase width of the 100mm I-Plus Rail, which is secured using the supplied wing nut kit.

Capable of handling spans up to 2.2 metres with minimal deflection (less than 5mm), this system provides outstanding structural integrity—ideal for both commercial and residential applications. Whether upgrading an outdoor space or refurbishing an aging deck, the Joist Hanger delivers strength, reliability, and ease of installation.

A fire rated tape can be used to help prevent galvanic corrosion between the Hanger & the aluminium joist.
