I posted this proposed project a few months back, looking for some beam sizing. I eventually told the client to get the project properly engineered then I would be happy to weld it. As you can see the handrails are not finished yet. The owner wants to finish it off with wood
The engineer spec'd the posts out as 3" x 3/16" A500 steel. The rest is 4" and 6" A36. The ground level flight of stairs had been acquired by the client. I installed those and added the remainder of the project, which cantelivers over his driveway.
