The W12x252 is a W-shape reference for engineers, detailers, fabricators, and students working with structural steel members. This page presents the source dimensions and section data together with a CAD download for drafting and coordination.
Use the values below as a reference for identifying the shape and reviewing drawings. Final member selection, strength checks, connection design, and detailing should be completed against the applicable project requirements and verified by a qualified engineer.

How to read the W12x252 reference
The W-shape designation identifies a wide-flange structural steel member. The source data lists the member’s reported depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These properties support shape identification, preliminary coordination, estimating, and design-document review.
Section dimensions and detailing
Depth and width help establish the member envelope for framing layouts, clearances, and connection detailing. Web and flange thicknesses describe the principal plate elements of the shape. The root fillet radius is important when checking fit-up, coping, bearing details, and interfaces with plates or connected members.
Sectional area and unit weight
Sectional area is a cross-sectional property used in structural calculations and material takeoffs. Unit weight expresses the member’s mass per unit length and is useful for estimating shipping, handling, erection, and framing loads. These values should be used with the project’s specified material and design requirements rather than treated as a substitute for engineering verification.
DWG and related steel references
The downloadable DWG can support drafting and coordination workflows. Confirm the drawing units, layer standards, title-block requirements, and project revisions before incorporating the file into a production drawing.

W12x252 FAQ
What type of steel shape is W12x252?
W12x252 is a W-shape, also commonly described as a wide-flange structural steel member. The source block provides its identifying dimensions and section properties.
What information is included for W12x252?
The reference includes depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight, along with a DWG download.
Can the W12x252 DWG be used directly for construction?
The DWG is a drafting reference and should be reviewed for units, project standards, revisions, and coordination requirements before use in construction documents. It does not replace design calculations or project-specific engineering review.
Does the listed unit weight determine design capacity?
No. Unit weight describes mass per unit length. Member capacity depends on the applicable design checks, material requirements, loading, support conditions, stability, connections, and other project-specific factors.
