Steelworker (abbreviated as SW) is a United States Navy occupational rating.
Steelworkers perform tasks directly related to fabrication and erection of pre-engineered structures, including steel reinforcement; control job site deployment of materials and equipment; direct and coordinate the composition, training and efforts of crews who fabricate, assemble, erect, position and join structural members and fabricated sections; maintain individual combat readiness and perform tasks required in combat and disaster preparedness or recovery operations.[1]
At the senior chief petty officer level, the Steelworker rating merges with the Builder and Engineering Aide ratings. At this level, they are referred to as a Senior Chief Constructionman (CUCS).
At the master chief petty officer level, they merge with all other construction ratings as a master chief seabee (abbreviated as CBCM).
