Open Web Joists


Open web joists are composite timber and steel joists forming an open web design. This provides the lightness of timber with the strength of a steel web. Our open web joists are lightweight, strong, easy to install and available in various lengths.

The open web design means that using these joists offers a flexible solution for any future internal building layout modifications, plus they eliminate costly cutting and drilling when installing services or incorporating modern ventilation and heat recycling systems.

Our web joists allow for longer clear spans or shallower depths than other engineered timber joists, and are ideal for floors or flat and mono-pitched roofs. They are also the perfect solution for environmental sustainability, as they can help cater for thicker insulation and mechanical heat recovery and ventilation systems, assisting with creating more energy-efficient buildings.

Open web joists are suitable for domestic, industrial and commercial applications.

open web joists are individually engineered, lightweight, durable and dimensionally precise. They are supplied along with all associated metalwork and timber ancillary materials, including metal connectors, temporary bracing, chipboard decking and any additional timbers.
