In the design of the fire-resistant façades,
the aesthetic and functional features of Secco Sistemi products remain unaltered. Both as an internal partition or as an external cover, the 4F AF system faithfully re-produces the project design, both in the materials used and in the building details. The excellent physical-mechanical characteristics make this system fire-proof also when using profiles with considerably reduced sections and depths. The elements and components have been specifically designed to meet the requirements of structural resistance to internal temperatures of 1000°C, maintenance of the external surface temperatures below 180° C, absence of flammable hot fumes, and unaltered preservation of performance for 90 minutes, for dimensions and weights of outsize glazing panels.
4F AF fireproof
system and performance
In the 4F AF system, which can be used both as an internal partition and as an external wall, there are subdivisions that, by implementing profiles of different sizes and using appropriate materials and types of glazing and specific accessories, can provide customized, tailor-made solutions; the system is thus made versatile to the point that possible resistance to fire can be varied from E30 minutes to EI90 minutes, with abatement of internal surface temperature. Performance has been tested by the best European certification laboratories.

size and variations
The size of the internal profiles and of the external covers is of 50 mm; the depth of the cover is of 16 mm in the mullions and 13 mm in the transoms.
materials of the covers
The covers of 4F AF are available in galvanized steel – with a wide range of colours and surface finishes – in stainless steel AISI 304, with stain finish, in stainless steel AISI 316L with shiny finish or scotch brite, in corten steel and in brass (copper alloy 0T67
possibilities for application
4F AF can be applied to any type of welded beam that has been specifically designed.
capacity of the frame to prevent the passing of flames, vapours and combustion gas
capacity of the frame to contain irradiation at a distance of 1 metre from the side exposed
capacity of the frame to contain the temperature of the side not exposed to flames
4F AF comes with specific ending caps, completely concealed, in stainless steel to join the heads of the mullions with the transoms in different possible combinations.
