Claim:
An elongated, reinforced construction element in the shape of a tubular or hollow profile, an I-profile, H-profile or another profile comprising a body and legs or arms that are protruding therefrom having an E-modulus of 5,000 Mpa or more with a wood-like appearance comprising a composite material of a matrix of thermoplastic synthetic material selected from the group consisting of polyolefin, PVC and polycarbonate, and at least 50% by weight of a mass of dried cellulose particles containing approximately less than 1% by weight of moisture and composed of a portion of small fibers in the size of 0.2 to 2 mm and a fraction of large elongated particles of a size 2 to 6 mm, said composite material having attached to exterior or in the interior thereof at least one continuous longitudinal reinforcement element which is in tight engagement with said composite material for providing tensile reinforcement or compressive reinforcement whereby any expansion of said construction element due to moisture uptake will be suppressed.
