       12 . The corner trim assembly of  claim 8 , wherein the at least one joint at which the workpiece is foldable includes a groove in workpiece defined by two mateable surfaces that converge at a central axis of the joint very near the surface with the imitation wood texture.  
   
   
       13 . The corner trim assembly of  claim 8 , wherein the synthetic resin workpiece comprises KOMA or AZEK trim boards.  
   
   
       14 . The corner trim assembly of  claim 8 , wherein the synthetic resin workpiece comprises a laminate has been formed by adhering at least two trim boards together.  
   
   
       15 . A railing arrangement having no externally viewable fasteners, comprising: 
 a vertical support column having a hollow core and polygonal cross sectional area near-seamless surface with an imitation wood texture and formed of a synthetic resin workpiece including a plurality of joints at which the workpiece is foldable; and    means for adhering two non-continuous ends of the workpiece.    
   
   
       16 . The railing arrangement of  claim 15 , further including at least one notch in the vertical column dimensioned to receive an end of a horizontal railing.  
   
   
       17 . The railing arrangement of  claim 15 , further including at least one hole through which a fastener is partially passable for attachment from within the hollow core to an end of a horizontal railing.  
   
   
       18 . The railing arrangement of  claim 15 , wherein the at least one joint at which the workpiece is foldable includes a groove in workpiece defined by two mateable surfaces that converge at a central axis of the joint very near the surface with the imitation wood texture.  
   
   
       19 . The railing arrangement of  claim 15 , wherein the synthetic resin workpiece comprises KOMA or AZEK trim boards.  
   
   
       20 . The railing arrangement of  claim 15 , wherein the synthetic resin workpiece comprises a laminate of at least two trim boards adhered together.  
   
   
       21 . The railing arrangement of  claim 15 , further comprising a column cap composed of synthetic resin having an imitation wood texture and having a bottom flange dimensioned so as to mate securely with the hollow core of the support column.  
   
   
       22 . The railing arrangement of  claim 15 , further comprising a handrail assembly including:
