The W30x148 is a W-shape steel section listed with dimensional, geometric, and mass-per-length information for reference. This page brings the key section data together with access to a DWG drawing for drafting and detailing workflows.
Use the listed values as the authoritative local reference for this page. For design work, verify material specifications, loading, stability, connection behavior, and applicable project requirements with the responsible engineer.
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 : 779.8 mm
Width : 266.7 mm
Web Thickness : 16.5 mm
Flange Thickness : 30 mm
Root Fillet Radius : 16.5 mm
Sectional Area : 281.29 cm2
Unit Weight : 220.8 kg/m
How to read the W30x148 reference data
The dimensions identify the overall section proportions and the thicknesses of the web and flanges. The root fillet radius describes the transition between these parts, which is relevant when interpreting drawings, clearances, coping, connection detailing, and section geometry.
The sectional area is a geometric property of the entire steel shape. It can support calculations such as axial-resistance checks when combined with the applicable material and design provisions, but it is not a complete design capacity by itself.
The unit weight expresses the listed mass per unit length. It is useful for estimating shipping, handling, and the self-weight contribution of the member. Convert and apply it consistently with the project unit system rather than treating it as a substitute for a structural load analysis.
AISC context and drafting use
The source identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings, as the reference context. That specification addresses design, fabrication, and erection requirements; the section values on this page should therefore be used alongside the complete project criteria and applicable design checks.
The downloadable DWG can help detailers and engineers begin a CAD workflow using the W30x148 profile. Review the drawing units, layer conventions, scale, and project drafting standards before incorporating it into production documents. Related internal resources may include the W-shape dimensions guide, steel section properties reference, structural steel terminology guide, and DWG detailing resources.
W30x148 frequently asked questions
What type of section is W30x148?
W30x148 is identified on this page as a W beam, also commonly described as a wide-flange structural steel section.
What information is provided for W30x148?
The reference lists overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight. These values describe the section and support preliminary reference, detailing, and estimating tasks.
What does the 148 designation mean?
The page title uses the designation W30x148, while the source separately provides the unit weight in kilograms per meter. Interpret the designation together with the listed source data and the governing shape reference rather than relying on the title alone.
Is the W30x148 suitable for a particular structural application?
Suitability cannot be determined from the section designation alone. A qualified engineer must evaluate loads, spans, bracing, material properties, limit states, connections, fabrication requirements, and applicable project criteria.
What is the DWG file used for?
The DWG provides a CAD representation of the W30x148 profile for drafting and detailing workflows. Check its units and geometry against the authoritative source data before using it in construction or fabrication documents.
