Structural steel
Structural steel is steel shaped and specified to carry significant loads in buildings, typically hot-rolled beams, columns and plates, fabricated and connected to a design.

What structural steel means
Structural steel describes steel members chosen and detailed to resist major loads. Typical elements are I-shaped beams and columns, hollow sections, angles and plates, usually hot-rolled and joined by bolting or welding.
Material grades and fabrication practice are governed by recognised standards, and industry information is published by bodies such as AISC.
A plain example
A building frame might use steel columns and beams to carry floors, while lighter framing forms partitions or infill. The split between the two is an engineering decision. Names and sizes here are only illustrative of the idea, not a design.
Why it matters
Structural steel framing underpins larger spans and heavier loads than typical studs. Fabrication needs approved shop drawings, and steel often figures as a long-lead item for large projects.
Common confusion
Structural steel is not the same as cold-formed steel, though both are steel and both can be structural when engineered. Do not infer capacity from the label; confirm with the engineer of record and the local authority. A load-bearing wall may use either material.
Practical checklist
A few considerations arise on projects that use structural steel.
- Fabrication needs approved shop drawings and a detailed connection design.
- Material grade, coating and corrosion protection should be stated in the specification.
- Plan delivery and erection sequence early, since steel often has a long lead time.
- Allow for inspection of welds and bolts where required by the project documents.
- Coordinate openings and fixings for other trades before fabrication.

Questions people ask
What distinguishes structural steel?
It is selected and detailed for major structural loads, usually hot-rolled and fabricated into frames.
Is cold-formed steel structural?
It can be structural when engineered, but it is a different product family.
Who designs steel connections?
A qualified engineer, with the fabricator producing detailed shop drawings.
