These risers start out with laser cutting 12ga cold roll sheet metal. After the parts are cut, the sides and base get formed to size. The risers are then tacked together and MIG welded out. All of the welds are then ground flush to make the entire unit look as if it was never welded. Once the grinding is complete the entire unit gets DA’d with an orbital finish. These risers are then finished with a proprietary powder coat that mimics blackened cold roll steel.
