Dindas I Joists

Superior Choice. Better Joist.

Dindas I Joists are engineered to perform and provide a cost-effective and lightweight solution for residential and commercial construction. I Joists provides the ideal choice for engineers, specifiers, and builders who want to provide their customers with high-quality floor systems. They provide consistent performance for the most demanding design applications. The Dindas I Joists are an inherently green product because they are a more efficient use of raw materials. To manufacture our EWP products, we use fast-growing, under-utilized, and less expensive wood species; therefore, large old-growth trees are preserved. By design, engineered wood products require much less wood to achieve the same load-bearing capability of traditional solid-sawn timber.
