Dindas I Joists are superior for cost-effective and lightweight residential and commercial constructions. They are engineered to perform consistently for even the most demanding design applications.

They are ideal for engineers, specifiers, and builders who want to provide their customers with high-quality floor systems. Dindas I Joist is environmentally friendly as it is more efficient in using raw materials.

We use fast-growing, under-utilised, and less expensive wood species to manufacture our EWP products. This way, large old-growth trees are preserved.

Engineered wood products are designed to require less wood to achieve the same load-bearing capability as traditional solid-sawn timber.
