Steel, Structural

Definition

Structural steel is steel that is rolled in a variety of shapes and manufactured for use as structural load-bearing members.

Purpose

The purpose of structural steel is to provide strong, durable, and reliable components for the construction of buildings, bridges, and other infrastructure, supporting loads and ensuring structural integrity.

Examples of Use

• High-rise buildings use structural steel beams and columns to support the framework and distribute loads.
• Bridges are constructed with structural steel girders and trusses for strength and durability.
• Industrial facilities employ structural steel in the construction of warehouses, factories, and heavy-duty structures.

Related Terms

• Beam: A horizontal structural member that supports loads.
• Column: A vertical structural member that transfers loads to the foundation.
• Truss: A framework of beams forming a rigid structure, used to support roofs and bridges.

Notes

Structural steel is preferred for its high strength-to-weight ratio, flexibility in design, and ability to withstand heavy loads and harsh conditions.
