Bernold Sheets are grooved, undulated and bent to a certain radius, manufactured in sizes up to 2/3mm and 1080x1200mm long.
Sheets are assembled over the steel arches, overlapped and hooked up with pins. Each sheet will cover approximately 1m2.
Ribs provided within the sheets every 120mm are considered equivalent to a concrete framework structure.
The Bernold System provides more security, efficiency and is economical.
