3 lengths plastic shelving (profiles?) (Burntwood WS7)

Used as shelving in garage, just wondering if anyone can make use of it rather than ditching it. 2 X lengths @ 211cms/83" long. 1 @ 198 cms/62.25" long, all 25 cms/10" deep, 2.5cms/1" thick. Slight damage to small area of surface on shorter piece. (Will give it a clean before collection!).
