A modular truss 14 for an escalator or moving walkway comprises a plurality of truss sections 16 connected together end-to-end. Each truss section 16 comprises a base portion 10, 10' and a pair of side portions 12 all formed of a fire resistant composite material, which may be a reinforced thermoplastic material such as a laminate of thermoplastic skins and a foam or honeycomb core. The truss 14 may comprise end truss sections 16 each including a bend 100 and at least one straight middle truss section 16. Examples of materials from which the skins may be formed include polyetherimide (PEI), Polyphenylene Sulfide (PPS), polyetheretherketone (PEEK) and polyetherketoneketone (PEKK). Examples of materials from the core may be formed include a thermoplastic, thermoplastic composite, paper, pressboard or aluminium, and may be bonded to adjacent surfaces of the skins by means of an adhesive, such as an epoxy resin adhesive.
