The entire table / desk is made of steel and was fabricated in my shop. The top is 1/4 steel plate that had been used as an easement on a loading dock. It has four 5/8 inch holes, one at each corner , that allowed it to be hung when not being used and I was careful not to ruin the integrity of it's patina by carefully cleaning the mill scale and coating it with zero sheen varnish. The legs are from a 50's table and welded to the top. It functions best as a desk against the wall because it is top heavy.
