Hi, just new to this group and hoping someone can answer my questions about using pallets to build a fence. What material are pallets made from? Could I make an1800mm high fence by deconstructing the pallets and running the boards horizontally? I was planning to build a frame around the boards and using posts set in readymade concrete. Has anyone done this before? Can anyone give advice about whether my plan will work? Thanks for any helpful advice. MarianMade
