Marks-Miller Post and Pole follows American Wood Protection Association standards in our treating process.  AWPA was founded in 1904 and is the principle Standards-writing body for the wood preserving industry in the United States.  Our products also meet Montana Department of Transportation standards.  

 

AWPA has made major reference changes in it's book of standards in recent years.  The "C" standards are no longer used and have been deleted from the Book of Standards.  They have been replaced with the "UC" standards in an attempt to make these treating standards more user friendly for Specifiers.
