PSE, or Planed Square Edge timber, is timber that has been machined smooth on all faces with square edges. It provides a clean, accurate and ready-to-use section for joinery, construction and manufacturing. 

PSE can be produced from both softwood and hardwood species and is suitable for applications where a smooth surface, accurate sizing and ease of finishing are required. 

Typical uses: joinery, framing, shelving, furniture, cabinet making, mouldings, shopfitting and general timber fabrication.
