What is the thickness of steel plate for steel bridge walkway?

The thickness of steel plates for a steel bridge walkway typically ranges from 1/4 inch (6 mm) to 1/2 inch (12 mm), depending on factors such as the load requirements, design specifications, and the intended use of the walkway. Engineers consider factors like pedestrian traffic, safety standards, and environmental conditions when determining the appropriate thickness. Additionally, local building codes and standards may also influence the final decision.
