  • Metal Web Joists

    Metal web joists comprise of an upper and lower timber member, connected by a steel web that provides strength. This results in a strong and light-weight joist solution.

Metal Web Joists

Our floor products are metal web joists. These joists are made from an upper and lower timber member, connected by a steel web, this element is what provides the joists strength. This combination of timber and metal webs results in a strong and light-weight joist solution.

Floor Joists1

The crowning glory of the metal web joist is the space the open webs creating a natural service void. No other product on the market offers this unique feature providing a void within the floor zone. Cables, pipes, waste pipes, ducting and more can be threaded through within the floor zone with no requirement for cutting, notching or drilling. The benefit of this is saving time which vastly reduces the labour time on site, resulting in lower labour costs and a faster build programme.

Made to measure Floor Joists

Our floor joists are a bespoke designed item. This means our designers ensure the floor joists are manufactured to the exact sizes required. Combine this with our site measuring service, and you can be assured our floor joists will drop effortlessly into place, giving you peace of mind.

Also, our CAD and laser-guided saw output and manufacturing jig ensures accuracy on every single joist that we manufacture.

Floor Performance

Many floor joist manufacturers prioritise low prices by using minimal materials to meet the base building code deflection limit (14mm), which can result in a bouncy floor.

At ETS, we take a different approach. We prioritise long-term performance and user comfort by "over-engineering" our joists for lower deflection, creating a firmer, more stable floor.

Our designers will discuss your project's needs and clearly indicate the deflection rating on the drawings. This commitment to quality and clear communication ensures you receive a superior floor joist system that enhances your project's value.

FAQs

Aren’t metal web floor joists expensive? Surely they’re much more expensive than I-beams, aren’t they?

This is a common misconception! While metal web joists may have a slightly higher upfront cost compared to I-beams, their design offers significant advantages that can lead to overall project cost savings. Here's why:

Increased Span with Less Depth: Metal web joists can achieve the same floor span as an I-beam, but with a shallower depth. This can be crucial in situations where maximizing ceiling height is important.

Reduced Need for Support Structures: Due to their strength, metal web joists can often span large distances without needing additional support beams or walls. This eliminates the labor, materials, and foundation work required for those additional structures, leading to cost savings.

In short, metal web joists may have a higher base price, but their superior strength and design can lead to significant cost savings on your overall project.

What is floor joist deflection, and why is it important?

Floor joist deflection refers to the amount a floor bends or bounces when weight is applied. Building codes have a maximum deflection limit (typically 14mm) to ensure a safe and comfortable walking experience. Exceeding this limit can lead to a bouncy floor that feels unstable.

What is the benefit of using joists with lower deflection?

At ETS, we prioritise long-term performance and user experience. Joists designed with lower deflection (meaning they bend less) create a firmer, more stable floor with minimal bounce. This translates to a higher quality product with greater comfort and peace of mind.

How do I know what level of deflection is right for my project?

Our designers will always discuss your deflection requirements and clearly indicate the designed deflection on the project drawings. We recommend discussing your needs and opting for a lower deflection whenever possible for a superior floor experience.
