I NOSTRI PRODOTTI

Alluminio

Most of the bonded sandwich constructions are  with aluminium honeycomb core with aluminium cover sheets. These sandwiches are characterized by high strength, stiffness and very low weight at the same time. 5M produces honeycomb sandwiches in the form of flat or spatially shaped panels with various types of ending, with pasted elements for further assembling and many other types. 






Due to our experiences and longterm innovative strategy we obtained award "Innovation of the year 2008" from Association of Innovative. The award concerns our accurate sandwich panels for building of radiotelescopes.

 
We are able to offer you panels with sizes, cell sizes or plate quality as you require. We have longterm experiences with production of panels with complicated shapes, with inserts inside (for threads for example), with edges,...
