Floor Joists
At Pemberton Timber Frame, we pride ourselves on delivering high-performance structural solutions that meet the demands of modern construction. One of the key components we offer in our timber frame builds is the Posi-Joist – a type of engineered floor joist that combines strength, versatility, and ease of installation to support a wide range of residential and commercial applications.
What are Posi Joists?
Posi-Joists, also known as open web joists or metal web joists, are engineered floor joists that feature a unique combination of timber chords and a steel web system. This design provides excellent structural integrity while allowing services such as plumbing, electrics, and HVAC to pass through the joists without the need for additional drilling or cutting.
Manufactured to exacting standards by trusted floor joist manufacturers, Posi-Joists offer all the performance benefits of traditional engineered joists – including strength, reliability, and longer clear spans – with the added advantage of easy service integration.
Advantages of Engineered Floor Joists
Flexible Design
Capable of spanning longer distances than solid timber, reducing the need for intermediate supports and enabling more open-plan designs.
Open Web Construction
Simplifies the installation of mechanical and electrical services, saving time and cost on-site.
Precision Engineering
Each joist is manufactured to meet strict quality standards, ensuring consistent performance and reliability.
Reduced Site Waste
Delivered to specification, which minimizes cutting on site and reduces material waste.
Lightweight and Portable
Easier and safer for installers to work with compared to traditional solid joists or heavier alternatives.
Engineered for Performance
As a type of engineered floor joist, Posi-Joists are specifically designed to perform under load with minimal deflection, reducing floor movement and noise. Their combination of timber and steel delivers a high strength-to-weight ratio, making them ideal for both floors and flat roof applications.
At Pemberton Timber Frame, we manufacturer the engineered floor joists to ensure our Posi-Joists meet the structural requirements of your project while aligning with your architectural and service layout needs.
