When to Specify Infill Panels for Commercial Staircases

Commercial staircase design requires coordination between architectural intent, structural requirements, and fall protection provisions. Infill panels are a key part of that coordination because they close the open areas within guardrail and stair railing assemblies. The wrong infill specification can create problems during inspection, require field modifications, or force a redesign after fabrication has already begun. Material selection also affects the appearance, durability, maintenance requirements, and overall performance of the completed stair system. For architects, engineers, contractors, and facility managers, selecting an appropriate infill configuration requires more than choosing a finish or visual style. This article explains what infill panels are, the applicable code requirements, common material options, and factors to consider when selecting an infill system for a commercial staircase..
