FAQs

What is a Steico I-Joist?

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 characterised 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.

What size I-beams do we stock?

We stock I-beams in 220mm, 240mm & 300mm depths with widths of 45mm, 60mm & 90mm. We also stock Glulam beams at depths of 240mm and 300mm deep.
