Light composite wood-based beams and columns I-traeger-weisser_hintergrund.png

I-beams or double T-profiles are wood-based composite elements, consisting of two flanges and a intermediate web which are glued together. They are intended to be used as loadbearing parts of building constructions, the utilization is limited to service class 1 and 2 (according to EN 1995-1-1). The top and bottom flanges are mainly made of strength graded structural timber (according to EN 338 or EN 14081), glued laminated timber (according to EN 14080) or Laminated Veneer Lumber (LVL, according to EN 14374). The webs are mainly made of Oriented Strand Board (OSB/3 or OSB/4) in accordance with EN 300 or hardboards according to EN 622-2. Glued joints of flanges to webs or webs to webs have to meet the requirements of EN 301 or EN 15425. The elements are used as columns, floor and roof beams. Materials, dimensions and mechanical properties of the product are manufacturer-related and are given in the European Technical Assessment (ETA) of the manufacturer. The reaction to fire is classified in accordance with the used materials, e.g. Euroclass D / smoke production s2 / flaming droplets d0. I-profiles or double T-profiles have the possibility to get a CE-certificate in accordance with ETA (according to ETAG 011 "Guideline for European Technical Approval of light composite wood-based beams and columns", used as European Assessment Document (EAD)) and the associated CE-certification. Additional European or national laws/regulations/implementations may apply.
