A self-locking support system includes a female profile having a first profile leg extending approximately orthogonally from a base, a first locking leg extending from the first profile leg, and a first tip extending from the first profile leg, wherein a gap is formed between the base and the first profile leg, and a first male profile having a fulcrum formed at an intersection of a second profile leg and a second locking leg, the second profile leg having a second tip extending therefrom. When the second locking leg is inserted into the gap, and a locking bead is positioned between the first and second tips, the first male profile is caused to rotate about the fulcrum and the first and second locking legs are caused to engage against each other.
