1. A corrugated construcvtin element formed from a sheet of material and having a base profile connected to at leat one leg profile, comprising at least two arrays of angular corrugations extending across their surface in a non-parallel direction to the principal axis L of the corrugated constructin element covering a surface area greater than 50% and less than or equal to 100% of the total surface area of the corrugated construction element, thereby increasing the effective thickness of the corrugated construction element with respect to the sheet of material from which it is formed, wherein the array of angular corrugations on the at least one leg profile extends at an angle Y ranging between 15° and 75° with respect to the to the principal axis L of the corrugated construction element, wherein the array of angular corrugations comprise at least one first array of angular corrugations and at least one second array of angular corrugations having an angle X therebetween ranging from 30 to 150 degrees, and wherein each array of angular corrugations is a series of continuously alternating peaks and troughs, wherein the peaks and the troughts each extend from the surface of the construction element, each peak and each trough being a V-shaped groove.
