Pier is in 7 sections. Each section is 3 ft x 10 Ft. We had it in 4 sections (40 ft) out then 3 sections abreast making a deck. Each section is in 2 pieces, a frame with steel brackets that hold onto the steel legs and a top. The legs are steel 1 and 1/2" pipe. (also available from Home Depot.com). May be configured in other designs.
