Observation towers typically consist of: structural framing (beams, columns, base plates, connections etc.), decking, stairs and railing. Decking usually comes in the form of a durable bar grating. Likewise, stairs are usually made with a grated tread that has been welded on at the factory.
Manufacturers will base the design of these components on your application requirements. For example, if accessibility is a concern, they will build closed riser stairs, as they are safer for those who have difficulty walking. In addition, to keep your staff and/or visitors safe, manufacturers can design observation tower stairs with handrails. Around the actual platform, they may place low guardrails, high and consistent guardrails or even strong, impact resistant glass or fiberglass material. If necessary, they can install bullet-proof glass.
Observation tower designers can either build your observation using traditional methods, or they can prefabricate your tower. Tower prefabrication is one of the most convenient approaches. Prefab observation towers are extremely practical, as they save on construction time and your bottom line. They are also adaptable. Plus, they are safe and secure.
Regardless, manufacturers always build observation tower components using galvanized steel, which is extremely strong, impact resistant, corrosion resistant and rust resistant. In addition, to increase resistance to scratches and abrasion, manufacturers can coat the components with a paint such as industrial grade polyurethane acrylic paint.
Before selling your your observation tower, trustworthy manufacturers will test them to make sure that they are structurally sound and can withstand the wind and seismic loads present in your location. They will also test them to make sure that they meet all applicable standard requirements, including ASTM requirements and IBC requirements.
