What are Posi-Joist
metal web joists?
Posi-Joist metal web joists are a hybrid structural building material that combine stress-graded timber chords with steel webbing, resulting in a robust, lightweight and adaptable system designed for use in both flooring and roofing applications.
Also known as Eco-Joists, Metal-Web and Easi-Joist each joist features a top and bottom chord, steel webs, and end supports. Unlike traditional solid timber joists, Posi-Joist metal web joists are engineered using specialist MiTek software and manufactured from our 12 Crendon Timber Engineering manufacturing facilities across England and Wales.
With the flexible design, Posi-Joist metal web joists enable adjustments to load capacities, specific configurations and placements before production begins.

Why Choose Posi-Joist?
There are many reasons to choose Posi-Joist metal web joists in your build:
Longer Spans
Posi-Joist metal web joists offer longer spans than conventional solid timber joists, all while being lighter in weight. This makes them an ideal choice for contemporary construction techniques that favour open plan living. With their extended span capabilities, Posi-Joist metal web joists often remove the need for internal load-bearing walls or central supports, enabling more versatile and spacious floor plans.
Easy Routing for other trades
The open web configuration of Posi-Joist metal web joists make them perfect for accommodating plumbing, electrical wiring, and ventilation systems. There’s no need for time-consuming drilling or notching, which speeds up installation and helps maintain the structural integrity of the joist. Whether it’s a new build or a renovation, Posi-Joist metal web joists deliver an efficient and budget-friendly option for routing essential services.
Lightweight
By using less material while maintaining strength, Posi-Joist metal web joists are considerably lighter than solid timber joists. This is especially advantageous on sites with limited access for cranes or when you want to avoid additional lifting equipment and costs.
Simple Installation
Custom designed and manufactured to suit your building’s dimensions, Posi-Joist metal web joists are straightforward to position during installation. They can also be supplied with trimmable ends, offering flexibility for irregular or older structures where perfect straightness is rare.
High Quality
Each Posi-Joist metal web joist is designed using advanced MiTek software and manufactured under strict factory conditions. This ensures consistently high quality and precision with every unit.
Zero Shrinkage
Unlike traditional timber, Posi-Joist metal web joists resist shrinkage and warping, two of the most common causes of squeaky floors, ensuring long-term performance and comfort.
