1. A panel having a profile with a width L1, comprising:
a first longitudinal edge including a first longitudinal rib including a top center part having a height H4 and width L4 and two lateral wings that extend from the top center part on either side and downward, the first longitudinal edge adjacent a first flange having a width L3 oriented in a plane P, wherein the two lateral wings form an angle α with the plane P, and adjacent the first flange, at least one projecting part including an upper plateau having a height H7 and width L7 and two lateral webs extending from the upper plateau on either side and downward, forming an angle β with the plane P; and
a second longitudinal edge adjacent the at least one projecting part including a second flange having a width L9 oriented in the plane P adjacent a second longitudinal rib including a top center part having a height H11 and width L11 and two lateral wings extending from the top center part on either side and downward forming an angle γ with the plane P, the first longitudinal rib and the second longitudinal rib having shapes that allow their respective overlapping,
wherein the widths L1, L3, L4, L7, L9, L11, the heights H4, H7, H11 and the angles α, β, γ meet the following relationships:
L7/L4≧5
L7/L11≧5
H7/H4≧0.4
H7≧((H4×(ab−be)−Labe)/(ae+ab))
H7≧((H11×(cb−be)−Lcbe)/(ce+cb))
where a=tan α, b=tan β, c=tan γ and e=tan 20° .
