At Steelscene, our Floor Joist Machine produces a 250 mm Cee section with thickness ranging up to 2.4 mm. This allows for spans up to 6m depending on live load.

The combination of specific punch tools gives this floor joist machine the ability to produce joists and perimeter channels directly from one machine via software instructions without any manual machine adjustments.

Steelscene’s floor joist system allows the builder to fabricate an accurate and timely flooring solution for any project using the same steel section for all members. Using CNC precision, service holes, bolt holes and tabs can be utilised for ease of fixing and running services through the system, saving time during installation.

A typical rectangular floor consists of two perimeter sections, with joists spanning in between. The perimeter sections are unlipped Cee sections, with the joists being lipped C-sections. This produces a 250mm deep ‘cassette’ and allows the flooring, or roof panel to seamlessly be installed on site. This system does away with the traditional bearer and joist method, allowing minimal time for installation.
