Operating in this field, we ware to  consider all the relevant norms in force. In this connection, the greatest difficulties were caused by  the impossibility to find in the market the tread able to bear 500Kg/m2 overload demanded by the  norm, preserving at the same time a valid technical and aesthetic aspect.                      Painted emergency staircase,                      the University of Physics of Bologna In a short period of time we have developed and performed a tread able to embody all the characteristics necessary to guarantee a maximum security to anyone who'll, unfortunately, have to use the emergency staircases. The denomination "Composita 120" derives directly from the modular desing that forms an integral part of the new system of production of Emergency staircases. Naturally, "Composita 120" step can be used not only for the construction of emergency and service stairs (can be made to measure), but also of steel mezzanines.                           Galvanized Emergency                           Staircase (Rome) Our service begins with the development of the proposal and comprises as follows: site inspection by precision instruments, graphic elaborations, static calculations performed by our authorized ing. Calculator, construction drawings, dip galvanization and packing of the product. Assembling brigades, specialized in putting the project into operation and winding means, can be offerred on request.                        Composita 120 step The "Composita 120" step - a product of our exclusive manufacture and desing, is realized in bent steel sheets (1 type steel) and has been specially developed for the construction of the emergency staircases. Preserving a valid aesthetic aspect it meets all the technical requirements of the norm relevant to emergency staircases, because it resists 500Kg/m2 overload, is slipless and heel safe thanks to funnel shaped slots 8mm wide; it is antipanic,                        SIP radio relay station (MN) because it forms a visual barrier necessary for those who, in panic-stiken flight, are forced to look downwards; it is self-cleaning,because transversal funnel shaped slots allow constant cleaning preventing detritus and ice accumulation on the whole surface. Being specialized in the construction of emergeny staircases designed to be integrated in the already existing architectural milieu, Logical LTD produces aslo industrial sheds and all kinds of medium-heavy steel structures.
