The purpose of this SAE Information Report is to provide concepts for rational selection and application of materials for Rollover Protective Structures (ROPS) and Falling Object Protective Structures (FOPS) and to provide information about the properties that should be considered in selecting and utilizing material in protective structures. While other materials could conceivably be used successfully, this report is limited to a consideration of steel with discussion on its mechanical properties and processing characteristics. Emphasis is placed on the toughness aspect (ability to resist brittle fracture) as this property is of paramount importance to structure integrity. It is emphasized that specific values for material properties have relevance to performance only in conjunction with specific design considerations such as structure size or weld joint detail and location.

The compositions and mechanical properties are only suggested to ensure good weldability and good formability in conjunction with control of mechanical properties. The particular design must be considered to ensure that the materials selected are compatible with the design. The indicated properties are intended to assure that the ROPS or FOPS will have meaningful resistance to brittle fracture. The impact toughness requirement is the conventional Charpy V Notch evaluation: it is primarily a quality control check and the indicated temperature does not directly relate to operating conditions. Three steel product categories are covered: hollow structural members, plates, bars and shapes, and castings.
