The W14x550 is a heavy W-shape reference for engineers, detailers, fabricators, and students working with structural steel framing. This page presents the section dimensions and properties listed in the AISC 16 source data, along with a downloadable DWG file for drafting workflows.
Use the values below as a section-reference starting point, then confirm material specifications, design assumptions, connection requirements, and fabrication details against the governing project documents and applicable engineering review.

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.

Unit Weight : 820.4 kg/m
How to read the W14x550 reference
The listed depth and width describe the overall section envelope. Web thickness relates to the central portion of the shape, while flange thickness describes the flange material. These dimensions are useful when checking clearances, connection layouts, detailing space, and compatibility with adjacent members.
The root fillet radius identifies the rounded transition between the web and flange. That transition should be considered when detailing plates, coping, fittings, and other components that approach the inside of the shape.
Section area and unit weight
Sectional area is commonly used in axial-force and material-quantity calculations. The listed unit weight supports preliminary weight takeoffs, shipping discussions, erection planning, and coordination with framing or connection models. These values do not by themselves establish allowable strength, resistance, stability, or connection capacity.
Drafting and design coordination
The supplied DWG resource can support CAD coordination and section-library workflows. Before using the file for fabrication or construction documents, verify units, layer conventions, insertion scale, project tolerances, and the relationship between the drawing geometry and the authoritative section data.
For related reference work, connect this page with resources covering W-shape dimensions, steel section properties, structural steel connections, AISC design terminology, and DWG detailing practices. These related topics help readers move from catalog identification to practical design and drafting review.
W14x550 FAQ
What information is provided for the W14x550?
The reference lists the section depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight from the stated AISC 16 source data. It also provides a DWG download.
What is the root fillet radius used for?
The root fillet radius describes the curved transition between the web and flange. It is important when checking fit-up and detailing components that meet the inside corner of the section.
Can the listed unit weight be used for final design?
It can support preliminary takeoffs and coordination, but final design should use the project’s governing criteria, verified section data, material requirements, load combinations, stability checks, and connection design.
Is the DWG file ready for fabrication?
The DWG is a drafting reference. Confirm its units, scale, geometry, tolerances, and project-specific detailing requirements before relying on it for fabrication or construction documentation.
