Standard common structural steel shapes

Structural steel shapes are defined by various global standards that cover aspects such as angles, tolerances, dimensions, and cross-sectional measurements. These standards also provide specific names for the different steel shapes. Some sections are created through hot or cold rolling, while others are fabricated by welding together flat or bent plates.

Here are some common structural steel shapes:

L-shape:

Commonly used as a corner section in construction, industry, commerce, transportation, or mining.

U-shape:

Characterized by two parallel sides forming a U-shape, offering high durability.

C-shape:

Resembles the letter "C" in cross-section, typically used for purlins in roofing structures due to its supportive properties.

Z-shape:

Similar to the C-shape but with a Z-like cross-section, also primarily used for purlins.

Tubular Hollow Cross-Section:

Highly resistant to twisting, often used in multi-axis constructions.

Flat Section:

Often referred to as plates, these are attached to construction parts to enhance load-bearing capacity.

Rectangular Hollow Cross-Section:

Similar to circular hollow sections, widely used in mechanical and construction industries.

Square Hollow Cross-Section:

Due to its shape, it's mainly used as a column or pillar in buildings.

Tapered Beams and Columns:

Commonly found in industrial prefabricated steel buildings.
