Posi Struts
You simply can’t afford to ignore the advantages of the Posi-STRUT system.
To start with, because Posi-Joist combines the lightness of timber with the strength of the Posi-Strut steel web, you can span far greater distances than would be possible with alternative timber products. The Posi-STRUT truss has special attributes which make it stand apart from the rest. Essentially it is a hybrid truss incorporating the versatility of timber and the strength of steel.
Unlike the conventional timber truss, the timber truss bottom chords on the Posi-STRUT truss are on flat with a broad surface horizontal. This makes the Posi-STRUT truss much stronger and more rigid than conventional timber trusses. Its wide surface also makes fixing of flooring easier as it provides ample width to join floor sheeting during installation and renders the truss more stable.
In many respects it is similar to the I-Beam. The cords can be compared to the I-Beam flanges and the Posi-STRUT to the web. Structurally the “I” section is a very efficient shape because it concentrates the bulk of the material to the outer edges.
This is also true of the Posi-STRUT truss and is a major reason why it performs better than the conventional timber truss. The steel web is the heart of the Posi-STRUT system, shaped like a boomerang it has the well proven integral Gang-Nail teeth which provide a very strong, reliable connection.
