Open web joists, (also known as open metal web joists) are another common way to structurally frame an upper floor in a residential building. They are also commonly used in flat roofs for both domestic and commercial buildings.
Donaldson Timber Engineering design and manufacture the MiTek Posi-Joist system. Open web joists are manufactured using TR26 structural graded timber for the flange along with the Mitek Posi-Strut Steel Web.
The major benefit of metal web joists is the open web which allows easy installation of the plumbing and electrical services. Furthermore, by combining the lightness of timber with the strength of the Posi-Strut Steel Web, it creates a joist that is capable of spanning greater distances than a traditional I-Joist.
Well suited for MHVR system, giving more flexibility within design and installation
Make installation of services easier, simple and cheaper
Precision-manufactured almost eliminating the need for site alterations
