The W8x13 is a W-shaped structural steel section identified by its nominal shape designation and unit-weight designation. This reference page brings together the source dimensions, material quantity information, and a CAD download for use during preliminary engineering, detailing, and drafting.
Use the listed values as a dimensional reference, then confirm the applicable project specification, material grade, connection requirements, and design assumptions before using the section in a structural design. For related terminology, see the site resources on steel shapes, section properties, and steel connections.

refer to : AISC 16
the American Institute of Steel Construction (AISC) Specification for Structural Steel Buildings (AISC 360-16), which is the 2016 edition of the AISC Specification for Structural Steel Buildings. It provides guidelines and requirements for the design, fabrication, and erection of steel structures in the United States.

Flange Thickness : 6.5 mm
Root Fillet Radius : 7.6 mm
Sectional Area : 24.77 cm2
Unit Weight : 19.4 kg/m
How to read the W8x13 reference
The source data identifies the overall depth and flange width, followed by web thickness, flange thickness, and root fillet radius. Together, these dimensions describe the rolled profile and help engineers and detailers check fit, clearances, cope conditions, and interface geometry.
The sectional area is useful for quantity calculations and for interpreting section-property references. The unit weight supports estimating steel mass and checking schedules, while design checks still require the applicable section properties, loads, restraints, material information, and governing design requirements.
Using the W8x13 DWG file
The downloadable DWG is a drafting reference for the W8x13 profile. Before placing it in production drawings, check the drawing units, insertion scale, layer settings, title-block conventions, and compatibility with the project CAD standard. CAD geometry should not be treated as a substitute for the authoritative dimensional data or for an engineer’s design verification.
Design and detailing context
The page references the AISC Specification for Structural Steel Buildings, AISC 360-16, which provides requirements related to the design, fabrication, and erection of steel structures in the United States. Apply that reference together with the project’s adopted requirements and the responsibilities of the engineer of record. Useful related topics include structural steel terminology, steel detailing, and structural design concepts.
W8x13 frequently asked questions
What does W8x13 mean?
W8x13 is a W-shape designation. The designation identifies the section family and its nominal depth and unit-weight convention; the source data on this page provides the actual reference dimensions and unit weight.
What information is listed for the W8x13?
The reference includes depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Can the W8x13 be selected for a structural member directly from this page?
No. Member selection depends on loading, span, restraint, stability, material, connection design, serviceability, and applicable project requirements. A qualified engineer must verify the complete design.
What is the DWG download used for?
The DWG can support drafting and layout work by providing profile geometry. Confirm units and project CAD standards before using it in construction or fabrication documents.
