Self-supporting metal panel system insulated with rockwool for wall and partition applications.
The ROCKSTEEL®WALL panel, manufactured in accordance with a system patented by Metecno, consists of two micro-ribbed steel sheets, with an insulation core of orientated fibre high density rockwool, arranged perpendicularly to the plane of the panel and positioned in strips, laid longitudinally with off-set joints and transversely compacted, in such a way as to completely fill the space between the metal facings.
Maximum panel lenght: L = 15,500 mm.
External and internal sheet
The following materials can be used:
- Prepainted galvanised steel S 280 GD
- Stainless steel AISI 304 - or AISI 430
Nominal thickness: 0.5 - 0.6 - 0.8 mm
Paint: METCOLOR System
Rockwool, density: 100 kg./m3
Thickness: 50 - 80 - 100 - 120 mm.
Reaction to fire
Reaction to fire is the degree in which a material resists combustion. With regard to this, materials are assigned a class (0 through 5): the higher the class, the higher the degree of combustion.
The ROCKSTEEL® WALL panels, thicknesses 50 - 80 - 100 - 120 mm, tested at the Instituto Giordano S.p.A., pursuant to the Ministerial Decree of 26/6/84, were classified 0/1 for reaction to fire in the wall position. Since the panel consists of two steel sheets with a layer of rock wool in between, the class 0 refers to the external surface and the class 1 to the insulation.
TABLE OF SAFE SPANS
Values guaranteed with steel sheets, thickness 0.5 + 0.5 mm. The spans l in metres, as a function of a uniformly distributed load p (daN/m2), have been obtained from tests carried out in Metecno laboratories and calculated to provide a deflection limit: f <= l/200 of the span and a minimum safety co-efficient that complies with the UEAtc standards for insulated panels, which have been established and are implemented by primary European Certifying Organizations.
