What Does the Tag Stapled to My ProWood Treated Lumber Mean?

Posted 29 March 2013 8:04 PM by prowoodlumber@ufpi.com

Each piece of ProWood® Professional Grade lumber carries an end tag which has essential information for any builder or do-it-yourselfer, including:

  • The preservative used
  • The appropriate end use (i.e., above ground or ground contact)
  • The quality standards it meets
  • Safe handling information
