Fire rated protection of junctions between KOROK® walls and structural steel

Ensuring fire-rated protection for junctions between KOROK® wall systems and structural steel columns and beams is critical for maintaining the integrity of fire protection systems in commercial and residential buildings.

This guide provides a quick reference for builders, engineers, architects, and designers to assess, design, and install fire-rated junctions without compromising the fire protection applied to steel structures. Whether you’re working with steel columns, beams, or other structural elements, KOROK® wall systems offer reliable fire resistance and acoustic performance.

Since fire protection linings and coatings are designed to meet the specific requirements of each column, beam, and loading condition, we recommend consulting your structural engineer or fire engineer for precise junction details.

For more information on fire-rated junction systems and KOROK® fire-rated wall systems, please refer to your project’s design team or review KOROK technical literature.

Installation

KOROK® is simple to install. You can get an installer group to do it for you – there are several installer groups around the country – or, if you’d like to install it yourself, we are very happy to offer free on-site training (subject to location). For more information on either option please contact us on 0800 773 777 or at info@korok.com.

We also have comprehensive installation guides for each and every KOROK® wall system. You can print these below, or contact us if you’d like us to send you hard copies.

KOROK® wall systems can be installed either vertically or horizontally, with clear steps to ensure a secure and high-performance outcome. Key steps include sealing the C-track with fire-rated sealant, precise cutting of panels, and correct placement using a tilt-and-snap action to lock panels together. Panels are fixed with screws at specified centres, and sealant is applied to maintain fire and acoustic integrity. Detailed guidance is provided for handling the last panels and ensuring proper finishing.
