To look accurate and to ensure that the pattern does not change over time, a paved surface needs to be finished with curbs. Also, in the industrial spaces, the edges have the role of delimiting the areas, framing and shaping alleys, streets and parking lots. Used in yards and gardens, we can use curbs of various shapes and colors to elegantly and practically outline alleys in gardens, terraces, or home access roads. L.T.D. "Radial Plus" offers a wide range of curbs for domestic use as well as for the delimitation of motorways with a thickness of 60, 80, 100, 150 and 180 mm.
