Values guaranteed with external face in steel, 0.5 mm thick, and internal face in steel, 0.4 mm thick or with both faces in aluminium 0.6 mm thick with external face in aluminium, 0.6 mm thick, and internal face in steel, 0.5 mm thick. The spans (m) as a function of a uniformly distributed load (kg f/m ), have been obtained from load tests carried out in Metecno laboratories, and provide a deflection f < /200 with a safety coefficient that complies with the UEAtc standards for insulated panels, which have been established and are implemented by primary European Certifying Organizations.

With external and/or internal steel thicknesses interior to the above mentioned ones, the guarantee on the admissible loads for the spans indicated in the table is maintained, while it is not maintained on the deflection limit and the safety coefficient. U value is Thermal Transmittance
Co-efficient expressed in Watt/m C and Kcal/m h C.
