Posi-Strut Open Web Joist System

One of our unique products, is our Open Web floor joist system.  The engineering design and steel webs which are part of our floor systems, are supplied and manufactured by Mitek Canada Inc. The Posi-Strut floor system offers a great deal of advantages over regular framing lumber.

Longer spans are achieved by a variety of available depths from 9 ¼’’, 11 7/8’’, 12 ¾’’, 14’’, through 16’’. Top and bottom chords are made from  4×2 K.D. lumber of different grades, giving the floor system an inherent strength and stiffness that meet or exceeds Building Code requirements.

We stress the fact that the floor system is in most cases made to measure for each individual project thereby saving time during installation, since very little or no cutting is required on site.  The 4×2 surface area of the joists also provides a wider surface area for the laying of the subfloor, not to mention the added bonus of a stiffer subfloor due to the shorter edge distance from joist to joist.

End details on the Posi-Strut make it extremely versatile for different installation and applications.  One noted feature is the top chord bearing option which allows the joist to hang from the top chord when installed on a ledger or a recessed beam.  This eliminates the need to install joist hangers and therefore decreases the overall installation time.  This is especially convenient with the increasing popularity of insulated concrete forms (ICF) in the use of foundations and walls.

Full layout drawings are supplied for the installation of all floor systems.
