B1322 - Structural steel

Operational Details
Structural steel refers to “I” and “T” shaped steel beams. These beams are similar to wooden beams, with the exception that they are capable of handling a much heavier load, and are less subject to being damaged, or deteriorating over time. An employer erecting structural steel usually is contracted to build frameworks for equipment at industrial plants, frameworks for commercial, high-rise and industrial buildings. Because of the weight they must be hoisted into place with heavy duty cranes, (either the contractors own machine, or subcontracted). The steel beams are placed on concrete foundations and pilings, poured by a foundation specialist who has been hired by the owner of the facility, or subcontracted by the steel erector.

Steel beams are installed using welding machines, bolting and riveting the members into place. Workers include engineers, who may design a building or equipment layout, estimators, and ironworkers, who are the ones who install the steel. The steel is ordered from a steel manufacturer and delivered to the job site as required. Any associated parts or fittings are usually looked after by the structural steel contractor, who may have a fabrication shop where components for the job are prefabricated.
