The W12x19 is a wide-flange structural steel shape identified in the source data as a W beam. This reference entry brings together its listed dimensions, sectional area, unit weight, and the applicable AISC specification context for drafting and engineering review.
Use the dimensional information below when coordinating steel shape references, connection details, and CAD work. The listed values should be checked against the project’s governing documents and verified by the responsible engineer before they are used for design or fabrication.
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 : 309.9 mm
Width : 101.9 mm
Web Thickness : 6 mm
Flange Thickness : 8.9 mm
Root Fillet Radius : 7.6 mm
Sectional Area : 35.94 cm2
Unit Weight : 28.2 kg/m
How to read the W12x19 reference
The dimensional entries describe the main geometric features of the section: overall depth, flange width, web thickness, flange thickness, and root fillet radius. These terms are useful when checking clearances, preparing connection details, coordinating adjacent members, or comparing the shape with other W-shapes.
Sectional area describes the amount of steel in the cross-section and is commonly used with other section properties during structural analysis. The source lists the area in square centimeters. Area alone does not establish the member’s axial, flexural, shear, or stability resistance; those checks require the appropriate material, loading, restraint, and design information.
Unit weight expresses the mass of the member per unit length. It can support estimating, material takeoffs, and handling discussions, but it should not be treated as a complete design capacity or as a substitute for project-specific engineering review.
AISC specification context
The source refers to AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings. That specification provides requirements and guidance related to the design, fabrication, and erection of steel structures in the United States. Refer to the governing project edition and applicable connection, material, and detailing requirements when using this shape in practice.
DWG and detailing use
The linked DWG resource can help with section representation in drafting and coordination workflows. A CAD outline should be treated as a reference: confirm the shape dimensions against the authoritative table and project requirements before using it for fabrication, connection detailing, or model exchange.
W12x19 FAQ
What type of steel shape is W12x19?
W12x19 is identified in this reference as a W beam, also called a wide-flange shape. Its listed geometry includes the depth, width, web thickness, flange thickness, and root fillet radius.
What dimensions are provided for W12x19?
The source provides the section depth, flange width, web thickness, flange thickness, and root fillet radius. It also lists the sectional area and unit weight. Use the authoritative values in the reference entry rather than relying on a drawing scale.
What does the unit weight represent?
Unit weight represents the listed mass of the steel member per unit length. It is useful for estimating and material takeoffs, but it does not by itself determine structural capacity.
Which AISC reference is associated with this entry?
The entry refers to AISC 360-16, the 2016 edition of the Specification for Structural Steel Buildings. Confirm the governing specification and project requirements before applying the information to design or construction.
Can the DWG file be used for fabrication?
The DWG is provided as a drafting reference. Verify its geometry against the source dimensions and obtain the required engineering and fabrication approvals before using it in production documents.
