The W12x45 is a W-shape reference entry for engineers, detailers, fabricators, and students working with structural steel members. The source data below identifies the section dimensions, material quantity measures, and the related AISC reference used by this page.
Use this page alongside the site’s resources on W-shapes, steel section properties, connection detailing, and CAD/DWG references. The listed values support preliminary coordination and drafting; final member selection and structural application require project-specific engineering verification.
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.

Flange Thickness : 14.6 mm
Root Fillet Radius : 12.8 mm
Sectional Area : 84.52 cm2
Unit Weight : 66.3 kg/m
How to read the W12x45 reference
The designation identifies a W-shape, while the dimensional entries describe the overall profile and its principal components. Depth and width help with layout, framing coordination, and clearance checks. Web thickness, flange thickness, and root fillet radius are useful when reviewing connections, coping, detailing, and fabrication interfaces.
The listed sectional area and unit weight provide quantity and material-reference information for estimating, modeling, and coordination. They should be read together with the project specification and the applicable design checks rather than treated as a complete design basis.
AISC reference and drafting use
This entry refers to the AISC Specification for Structural Steel Buildings identified in the source content. A standards reference helps establish the context for the shape data, but it does not replace the requirements governing a particular project, connection, load condition, or fabrication procedure.
The downloadable DWG can support CAD coordination and detail development. Before incorporating it into a drawing set, check units, insertion scale, layer conventions, orientation, and the fit with project-specific connection and detailing requirements. For related guidance, see the site’s references on steel drafting and structural connection details.
W12x45 frequently asked questions
What type of section is W12x45?
W12x45 is identified in the source content as a W beam. The page provides its principal dimensions, section area, unit weight, and the associated AISC reference.
What information is included for W12x45?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These values are intended for reference and coordination with the authoritative local data on this page.
Can the W12x45 DWG be used directly for construction?
The DWG is a drafting resource, not a substitute for project drawings or engineering review. Confirm its scale, units, orientation, and detailing compatibility before using it in a drawing or model.
Does the W12x45 entry by itself prove suitability for a design?
No. Member suitability depends on the complete design situation, including loads, unbraced conditions, stability, connections, material requirements, and project criteria. A qualified engineer should verify the application.
