The W8x58 is a W-shape steel beam reference for engineers, detailers, fabricators, and CAD users. This page brings together the source-listed section dimensions, section area, unit weight, and a downloadable DWG resource.
Use the data below as a concise shape-reference entry, then verify design assumptions, material requirements, connection details, and applicable project criteria before using the section in construction documents.
W Beam
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.
Depth : 222.3 mm
Width : 208.8 mm
Web Thickness : 13 mm
Flange Thickness : 20.6 mm
Root Fillet Radius : 9.9 mm
Sectional Area : 110.32 cm2
Unit Weight : 86.6 kg/m
How to read the W8x58 reference
The listed properties describe the geometry and basic mass characteristics of the shape. Depth and width help establish the section envelope for modeling and detailing. Web thickness and flange thickness describe the principal plate elements, while the root fillet radius identifies the transition between the web and flange.
Sectional area is useful when reviewing material quantity and axial-property calculations. Unit weight supports estimating and handling discussions, but it should not be treated as a substitute for project-specific design checks or fabrication information.
Design and detailing context
The source identifies the AISC Specification for Structural Steel Buildings, AISC 360-16, as the referenced specification. That context is useful when connecting this shape entry to related resources on W-shape terminology, steel section properties, structural steel connections, and steel member design. Engineers should confirm the governing specification, material grade, loading, stability requirements, connection design, and detailing constraints for each project.
DWG resource
The downloadable DWG can support preliminary CAD coordination, layout, and detailing workflows. Treat downloaded geometry as reference information and confirm its scale, units, layer conventions, and compatibility with the project model before relying on it for fabrication or final documentation.
W8x58 FAQ
What type of section is the W8x58?
It is identified in the source as a W beam, part of the wide-flange structural steel shape family.
What information is provided for the W8x58?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Which specification is referenced?
The source references the American Institute of Steel Construction Specification for Structural Steel Buildings, AISC 360-16.
Can the DWG be used directly for fabrication?
The DWG is best treated as a drafting reference. Confirm geometry, units, project standards, and fabrication requirements before issuing any production documentation.
Does this page replace structural design review?
No. Section data must be evaluated with the applicable loads, restraints, materials, connections, limit states, and project requirements by a qualified design professional.
