Steico’s I Joists Manufacturing Process

STEICO I-joists consist of two components: the so-called “flanges” on the top and bottom sides and the “web” in the middle that connects the two flanges.

The flange material is made of highly durable STEICO LVL laminated veneer lumber, one of the most resilient wood-based materials available.

The web is made of STEICO Natural Fiber Boards, a wood-based material characterized by particularly high shear strength. 

In combination, this results in an innovative structural product that combines load-bearing capacity with low weight and maximum energy efficiency.
