Stairs are a primary means of egress, exit, and floor-to-floor access for buildings with multiple floors or a change in rise. Metal stair systems designed for commercial and industrial applications can be fabricated out of steel, stainless steel, cast iron, and aluminum. This course evaluates types of pre-engineered steel stair systems and includes discussions on advantages, class, fabricator vs. manufacturer, railings, stair flight and landing construction, connections, and building code requirements.
