The W40x215 is a wide-flange structural steel shape listed in the SteelSTD W-shape reference. This page brings together its published geometric dimensions, sectional area, unit weight, and CAD download information.
Use the source values as a reference for preliminary layout, detailing, quantity review, and section identification. Final member selection and connection design require project-specific engineering checks under the applicable design requirements.
W Beam

How to read the W40x215 reference
The listed depth and width describe the overall envelope of the shape. These dimensions are useful when checking framing clearances, member interfaces, architectural coordination, and drawing space.
Web thickness and flange thickness describe the principal plate elements of the rolled section. They help explain the shape’s geometry and are commonly reviewed alongside section properties when assessing member behavior and connection detailing.
The root fillet radius identifies the transition between the web and flange. This curved region matters when detailing plates, stiffeners, copes, seats, and other components that meet the rolled profile.

Drafting and verification notes
Before placing the profile in a drawing, confirm the required orientation, member line, end conditions, coping, holes, plates, and connection geometry. When the DWG is used as a drafting aid, compare its profile representation with the authoritative dimensions shown on this page and coordinate units with the project document standard.
W40x215 FAQ
What type of section is the W40x215?
It is a W beam, also known as a wide-flange structural steel section.
Where are the W40x215 dimensions listed?
The source content lists the section depth, width, web thickness, flange thickness, and root fillet radius, along with sectional area and unit weight.
Which specification is referenced for this shape?
The page refers to AISC 360-16, the American Institute of Steel Construction Specification for Structural Steel Buildings identified in the source content.
Is a DWG file available?
