Mitek Joists Here

Let’s return to Mike Harris’s kitchen. He switched to Mitek 16-inch-deep I-joists spaced at 19.2 inches on center. The result:

The “I” shape is not accidental. Just like a steel I-beam, the design places material where the stress is highest—the top flange handles compression, the bottom flange handles tension, and the thin web resists shear forces. This gives a Mitek joist an extraordinary strength-to-weight ratio. A 24-foot Mitek joist weighing 80 pounds can support the same load as a 150-pound solid 2x12. mitek joists

Solid timber joists are prone to shrinkage and warping, which can lead to squeaky floors over time. Posi-Joists, manufactured from kiln-dried timber and steel, are dimensionally stable, virtually eliminating the risk of shrinkage. They also provide a wider, more stable fixing surface for floor decking. Applications: When to Use Posi-Joists Let’s return to Mike Harris’s kitchen

Because the system is "open web," there are large triangular voids between the chords, as opposed to the solid center found in I-joists or dimensional lumber. Just like a steel I-beam, the design places

MiTek Industries is a major supplier of software, engineering services, and manufacturing equipment to the construction industry. While they do not manufacture the joists themselves in a traditional sense, they provide the patented design system and the machinery (such as the Roof and Floor Truss Systems) that allows fabricators to produce these components.

Their long-span capability can eliminate the need for costly internal load-bearing walls or steel beams. Technical Support and 3D Modeling
