With a choice of engineered I-Joists or Metal-web Posi-Joists, we can provide the best roofing and flooring solutions for your development.

I-Joist is a structurally engineered timber joists used in many new homes. They are made from a web sandwiched between top and bottom flanges, which is glued, pressed and heat cured. The I-shaped cross-section gives them their name, but also means they can carry far heavier loads than a conventional timber joist of equivalent weight.

Posi-Joist is a metal web joists that offers greater design freedom and easy access for installation of services. We use software from MiTek to design and manufacture Posi-Joists for residential and commercial projects.

With their open web design, Posi-Joists allow services to be installed quickly and with greater ease compared with more traditional solid timber joists.
