Plastic building material components

Abstract

A plastic extruded building material component such as picket fence or skirting component.

       13 . The fencing assembly of  claim 10  wherein said at least one post is made from polyethylene coated sixteen gauge galvanized steel.  
   
   
       14 . The fencing assembly of  claim 10  wherein said components include building pickets extruded from ultra violet stabilized polyethylene.  
   
   
       15 . The fencing assembly of  claim 10  wherein said textured surface is created from injecting an agent having a melt temperature different than that of the base material of the component during the thermoforming process.  
   
   
       16 . The fencing assembly of  claim 10  wherein said textured surface is created from injecting a blowing agent having a melt temperature different than that of the base material of the component during the extrusion process.  
   
   
       17 . The fencing assembly of  claim 10  wherein said colored streaks are created by adding one or more coloring agents having different melt temperatures.  
   
   
       18 . The fencing assembly of  claim 10  wherein said colored streaks are created by adding one or more coloring agents having differing viscosities.  
   
   
       19 . A method of creating a building material component that provides an appearance of a wood material, said method comprising the steps of: 
 extruding a plastic material into the desired shape of the building material component;    providing a first class of agents into said extrusion step having a different melt temperature than said plastic material to create a texture in the surface of the building material component.    
   
   
       20 . The method of  claim 19  wherein said method further comprises the step of: 
 providing one or more of a second class of agents into said extrusion step having different colors and different viscosities to provide streaking in the surface of the building material component.    
   
   
       21 . The method of  claim 19  wherein said step of providing one or more second class of agents further includes providing one or more agents having different melt temperatures.  
   
   
       22 . The method of  claim 19  wherein said step of extruding a plastic material into the desired shape of the building material component further includes: 
 extruding the building material component into the shape of a picket for a fencing assembly.    
   
   
       23 . The method of  claim 19  wherein said steps of providing a first class of agent for creating texture and of providing a second class of agents for creating color streaks includes: 
 providing an extruder screw that disperses and heats the first class of agents and second class of agents at different rates.    
   
   
       24 . A method of creating a building material component that provides an appearance of a wood material, said method comprising the steps of: 
 extruding a plastic material into the desired shape of the building material component;    providing one or more of a first class of agents into said extrusion step having different colors and different viscosities to provide streaking in the surface of the building material component.
