CHARACTERISTICS
- Product: Wooden formwork H20 beams
- Wood species: Spruce
- Wood moisture: 12 % +/- 2 % at delivery
- Weight: 4.5 kg/m
- Glue: Melamine resin based adhesive, adhesive type I EN 301 - approved for use with load bearing timber components
- Surface protection: Water repellent colour glaze is used to ensure the beam is waterproof
- Chord: Made of carefully selected spruce wood; Finger-jointed, solid wood cross-sections, dimensions 80 x 40 mm; Finger-jointed chords; Web-milling on the opposing side of the core (left-sided chord surface); Planned and chamfered to app. 0.4 mm
- Web: 3-ply solid wood panel, laminated, vertical growth-ring orientation
- Surface protection: The entire beam is treated with a water-resistant colour stain
Support: Due to the 3-ply solid wood webs, Extrabeam H20 and Extrabeam H20+ can be cut into and supported at any length.
