The components which make up this structural system are:

 Purlings.
 Frames:

The frames are what support the structure. Each frame consists of a set of profiles –columns and roof beams- assembled with high-resistance screws. These profiles are built-up from steel plates and their sections vary according to length in an attempt at finding the optimum weight/strength relationship. The steel used is always S235 or S275 EN 10025:94 quality and minimum thickness stands at 5 mm.

The steel plates which forms the flanges and web of each member is worked in the Automatic Fitting and Submerged Arc Welding (SAW) Centre. The main feature of the process is that the bracing and welding processes are performed at the same time, thereby avoiding the welding tensions inherent in more conventional systems. Añuri’s joints are welded on all 4 angles as opposed to the 2 normally welded on its competitor’s products.

Each frame is dimensioned using the powerful ANSYS Finite Element analysis programme. The different computer applications developed by Añuri’s technicians use this basis to efficiently analyse the forces/deformations at play on the frame and the deformation/warping the sides of the frame are subject to. Only in this way can the stability of the structure come guaranteed.

In order to cut costs to the full, the frames are joined to the foundations via articulated supports when considered appropriate. These supports prevent the transmission of bending moments to the footing, which can, therefore, be a lot smaller than otherwise.
