One of the most important assets of our Deltaracks is the lightness of the total structure. The birch plywood that we have chosen as a base material is not only extremely strong but also relatively light, which brings on obvious advantages for the usage and transportation. The unloaded weight of a conventional metal rack for glass is roughly 175 kg, while a comparable B4L Deltarack weighs just 36 kg – only 20 per cent of the weight of a conventional solution.
