Anti-noise barrier with sound-insualting and soundproofing panel made of pre-galvanized sheet steel. The panels has a box-shaped structure made from sheet steel in the thickness 10/10, 12/10 and 15/10 mm, pretreated according to the Sendzimir industrial galvanizing process and painted. NOMINAL DIMENSIONS: length: 3000 mm, height: 500 mm, thickness: 100-120 mm, length can be extended up to 4800 mm..
The two sheet metal half-shells will contain either a rock wool sound-absorbent blanket or CIRFIBER, a panel made from 100% recyclable polyester fibres. The ends will be closed off with patented plastic heads ensuring perfect sealing between the panel and its HE140/160 upright.Patented groove compensators, if required, can be instantly installed on the head and allow the same panel to be used on different HE profiles with larger grooves, up to the size HE240. The panel can be mono-absorbing (perforated on one face) or double-absorbing (perforated on both its faces).
Stability: thanks to the sturdiness of the material and its special corrugation structure, the panel features excellent mechanical strength.
Durability: outstanding resistance to weathering thanks to galvanising and painting treatments.
Good Value: excellent performance is guaranteed also by the 10/10 mm version – with a favourable impact on pricing.
Resistance: Wind- and impact-resistant.
Low maintenance: thanks to the patented heads and compensators, replacing a damaged panel has never been so quick and easy.
Highly suitable for personalisation: the plate metal can be painted in all RAL chart colours.
Acoustic performance: sound absorption class A4 – Sound insulation class B3, corresponding to the highest performance classes according to UNI EN 1793 standards.
