A Home Remodeling Project Requires Safety.
A colleague needed a guard rail for a 2nd story stair opening. He gave good critical dimensions and I came up with this, based on similar railings designed by an engineer at work which used stock materials (no need for an exotic BOM or expensive sourcing for this budget project).
As you can see, it’s made of square steel tubing, plate, and square bar for pickets or balusters. This is a 2-piece welded assembly, which makes it easier (or possible) to get it up a staircase and install it.
