The table illustrates the mechanical characteristics of the fiberglass profiles, for the determination of which reference is made to the standards EN 13706-2, EN ISO 527-4, EN ISO 14125 and EN ISO 13130. The values shown in the table are the result of tests made on standard profiles with resins and different thicknesses. For the structural calculation always refer to the values shown in the specific technical data sheet of the product to be used.
