Structural building materials or articles obtained from a composition comprising crop plants or residues therefrom and/or virgin or recycled polyolefin materials or plastics blended and combined with coloring agents which give the particular color desired to the structural articles and with bonding agents such as the natural thick sticky substance commonly found in sugarbeets to provide the necessary cohesiveness to the structural articles and/or with ultraviolet stabilizers and/or impact modifiers, which may be extruded through a profile die or compression molded or injection molded in a conventional mold in heated platens as such to produce the desired structural articles such as door jambs, door sills, garage jambs, deck materials, sheets of varied dimensions, sidings, shingles, door slabs, window sashes and frames, moldings, etc., which effectively replaces wood as the primary component of such structural articles.
