As a variation to one piece welded posts, Shelving Systems offer a two piece equivalent that has the upright and the base leg supplied separately.
This assembles and replaces directly the one piece posts, but can be stored and shipped more efficiently
Shelving Systems posts uprights are a one piece tube with a 30mm x 70mm profile and are 50mm pitch.
They are punched both sides to allow them to be supplied as a single or double sided version
They are available in all standard colours and sizes.
