A metal fence. Two metal posts are inserted into a concrete footing. Hollow metal boards are connected between the metal posts. In a preferred embodiment, the hollow metal boards are filled with acoustical insulation for noise reduction.

What is claimed is: 
     
         1 ) A metal fence, comprising:
 A) at least two metal posts,   B) footing wherein said at least two metal posts are rigidly inserted into said footing, and   C) at least one hollow metal board connected between said at least two metal posts.   
     
     
         2 ) The metal fence as in  claim 1  wherein said footing is concrete footing. 
     
     
         3 ) The metal fence as in  claim 1  wherein said at least one hollow metal board is a plurality of extruded hollow metal boards wherein each hollow metal board is filled with acoustical insulation. 
     
     
         4 ) The metal fence as in  claim 1 , further comprising:
 A) a metal top rail slidingly connected between said two metal posts, and   B) a metal bottom rail slidingly connected between said two metal posts,
 wherein said metal boards are slidingly and vertically connected between said two metal posts and said top rail and said bottom rail. 
   
     
     
         5 ) The metal fence as in  claim 1 , further comprising:
 A) a metal top rail slidingly connected between said two metal posts,   B) a metal bottom rail slidingly connected between said two metal posts,   C) two metal vertical channels each adjacent to one of said two posts and each sliding connected between said top rail and said bottom rail,
 wherein said metal boards are slidingly and horizontally connected between said two vertical channels and said top rail and said bottom rail.
