Product Description

The HT20 Beam has a high load capacity throughout their length, is easy to handle and quick to assemble. It has a minimum weight to load capacity ratio making it ideal form formwork.

Beams plus is produced in various standard lengths and has a solid plastic cap prevents premature chipping on the chord ends.  Moreover, the superior quality solid wood chords combined with triple laminated solid wood webs guarantee above-average durability.

Supports can be placed between beams at any point and can be used in any kind of formwork.

Areas of application

  • Ceiling formworks
  • Wall formworks
  • Bridge formworks
  • Tunnel formworks
  • Special formworks
  • Scaffolding
  • Working platforms

Permissible distances between main beams and supports

Example of calculation: Floor thickness: 20 cm, distance between crossbeams: 75 cm; we are looking for the distance between the main beams and the supports. The permissible distance between main beams according to table 1 = 2,58 m. The identical or next smaller distance between main beams in table 2 = 2,5 m. Look for the permissible distance between supports in table 2, read downwards in column «2,50 m» and sideways in row «20 cm» floor thickness, the result is 1,27 m. Caution! Examine the supports to ensure the corresponding carrying force.
