USES AND CHARACTERISTICS The FRP walkways are built by assembling fiberglass and polyester resin pultruded profiles and gratings; they assure several advantages compared to the normal metal ones: a. High resistance to chemical and atmospheric aggressions b. High mechanical/weight ratio f. High dielectric properties h. Easy to install Structures are designed and built accordingly to the UNI EN ISO 14122-2-3 norm.

MATERIALS 3.1 WALKWAY Self-bearing structures These structures are built with C and/or I profiles fixed together with secondary beams of the same type, which are chosen accordingly to the specific load request. In any case, the minimum considered load capacity is 2kN/m2 (distributed load) accordingly to the UNI EN ISO 14122-2 norm. The junctions are made with stainless steel plates and bolts & nuts as described below. Walking...

INSTRUCTIONS FOR DESIGN ENGINEER The design of the walkway is determined by the calculation of the maximum span, which corresponds to the most restraining of the two conditions: maximum action on main profiles (o < Oadm.) or the maximum deflection (f < 1/200 span), as shown in the table below. Walkway is considered as a simply supported beam (isostatic structure) uniformly loaded. UNIFORMELY DISTRIBUTED LOAD 200 kg/m2 WIDTH of...
