About Duofor

Duofor® dovetailed sheets are the improved generation of dovetailed sheeting.

The exact profile geometry of Duofor® dovetailed sheets (according to EN 1090-2), in combination with concrete, cement screed or lightweight concrete, enables a bearing construction of composite floors on timber or steel girder constructions. 

Floors with Duofor® dovetailed sheets have the advantage of low height and low weight. 
The characteristics of Duofor® dovetailed sheets:
  • Esay to install due to installation markings on panels
  • Traffic loads up to 5.0 KN/m²
  • Fire resistance
  • High air and impact sound values according to Eurocode
  • Durable due to use of high quality galvanized steel sheets
  • Thin floor thickness (from 36 mm)
  • Free spans (centre to centre) of up to 2.5 m
