Protective cover sections and sealed assemblies thereof fully enclose structural shapes such as I-beams and the like to protect them against bacterial growth, mildew, corrosion and the like. Each cover section is generally thin-walled, substantially rigid, flexible and tough so as to resist chipping, denting and peeling. Each cover section has flexural joint portions that facilitate adjustment thereof to cover a range of structural shape dimensions. On-site applied assemblies of the cover sections are adaptable to a variety of existing structures and include a pair of cooperating cover sections with opposed edge portions of one connected to edge portions of the other at a pair of opposed, sealed, continuous seams extending along the cover. A cooperating pair of cover sections overlaps a next adjacent cooperating pair of cover sections and these pairs are connected at a sealed, continuous, circumferential seam and the ends of the assembly of cooperating pairs are closed by sealed, continuous, circumferential end seams. The assemblies closely conform to the cross-sectional shape of the structural shape covered and are secured thereto for a relatively close fit. In an adjustable form for making these cover sections one base has a plurality of interchangeable flange-forming sections of different dimensions for forming a cover for a range of flange dimensions.
