Technical description

This is a service boardwalk built during the renovation of the Mendrisio highway exit, so as to make the pipelines pass over the FFS railway layout.

The structure rests on two pillars and is composed of two main curved trusses made of tubular hot-rolled profiles, and of two rows of transverse beams.

A footpath ground, made of longitudinally placed corrugated metal sheets, rests on the bottom of the first row of crossbeams. 

While the stainless steel water pipelines and the conduits for the electric cables and the optical fiber are suspended over the second row of crossbeams. A grid for the maintenance services rests on the upper part of this second row.

Sideways, on the inside of the structure, the boardwalk is stopped with corrugated metal sheets vertically placed.

Essentially the whole structure and the plugging were assembled in the workshop. It was necessary to create two sections so as to be transported. These sections were  assembled and welded in the building site using an appropriate auxiliary structure.

Surface treatment: class C3 according to EN 12944
