1. Increased Span

Due to their increased strength, builders benefit from metal web joists; greater flexibility in the spans. Effectively, they can achieve longer spans while potentially avoiding the necessity of load bearing internal walls which in turn can reduce the overall cost of build.

2. Waste Reduction

Metal web joists are manufactured to size in-house and so onsite alternations are not required.

3. Open Web Design Saves Time

An open web structure allows plenty of space for services which eliminates the need for drilling or notching. This structure can also accommodate larger services such as mechanical heat ventilation recovery systems. Timber I-joists do come with pre-stamped pop-out holes but these are vary rarely in the right position.

4. Speed of Installation

There are no onsite alterations which allows for speed of installation.

5. Environmentally Friendly

Metal web joists use less timber than I-joists, making a positive impact on the environment.

6. Lightweight

Despite their robust design metal web joints are lightweight, making them easier to handle.

7. Sound Performance

The addition of rigid strong backs can reduce vibration and improve sound.

8. Long-Term Stability

Metal web joists contain less prefabricated timber and so retains little water after production. This results in reduced risk of shrinkage and allows for greater stability.

9. Larger Working Surface Area

A larger bearing surface area allows for easier fixing of flooring and ceiling materials.

10. Improved Air Tightness

Metal web joists can be designed top hung eliminating the need for a rim board, consequently improving air tightness and reducing thermal bridging.
