Written by

This topic includes information related to catwalks installed during construction. Catwalks are narrow elevated walkways with railings and handrails, which allow building personnel to reach difficult locations or pedestrians to cross difficult terrain. Catwalks are commonly located in theaters, above stages, between portions of a building, along the side of large industrial tanks and as part of pedestrian bridges.

Metal Stairs

Written by

Metal stairs are an important component of most multi-story buildings and provide a variety of design options. Typical design configurations are straight run, L-shaped, and switch-back. Spiral stair systems fabricated from metal components are also common and offer many design options. A metal stair system can be designed as a multi-story self-supporting structural unit, independent of the building structure, or as a single flight of stairs that is structurally supported at each floor or landing. One of the biggest benefits of a self-supporting stair system is that it can be installed independently of the floor structure. More commonly, stair systems are designed in single flight segments and require structural support through a connection to a floor structure or vertical columns. Metal stair systems are fabricated at a metal shop or facility based on job-specific shop drawings and are delivered to the site in segments to facilitate erection.
