W16x45 is a W-shaped structural steel section identified by its nominal depth series and weight designation. This reference lists the section dimensions, area, unit weight, and root fillet radius provided in the source data.
Use the dimensional information when reviewing steel framing layouts, connection clearances, fabrication details, and CAD drawings. For broader context, compare this section with other W-shape designations and review related guidance on section properties, steel terminology, and connection detailing.
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.

Web Thickness : 8.8 mm
Flange Thickness : 14.4 mm
Root Fillet Radius : 10.2 mm
Sectional Area : 85.81 cm2
Unit Weight : 67.4 kg/m
How to read the W16x45 reference
The source identifies this member as a W beam and references AISC 360-16, the AISC Specification for Structural Steel Buildings identified in the original content. The listed depth, width, web thickness, and flange thickness describe the principal rolled geometry of the section.
The sectional area is useful when reviewing material quantity and area-based engineering calculations. The listed unit weight supports preliminary steel takeoffs and framing estimates. These values should be kept distinct from section properties such as moment of inertia, radius of gyration, and section modulus, which are separate data items and are not listed in this reference.
Detailing considerations
The root fillet is the curved transition between the web and flange. It matters when checking connection components, coping, stiffeners, seats, and other details that approach the web-to-flange junction. A drawing or connection design should account for the actual rolled shape rather than assuming a sharp internal corner.
The accompanying DWG resource can support drafting and coordination workflows. Before using downloaded geometry for fabrication or design, confirm the drawing scale, units, layer conventions, and project requirements. Structural adequacy, connection resistance, stability, and member selection require verification by a qualified engineer using the applicable project criteria.

W16x45 FAQ
What type of section is W16x45?
W16x45 is a W-shaped structural steel beam designation. The source data provides its principal dimensions, sectional area, unit weight, and root fillet radius.
What does the “x45” designation indicate?
In a W-shape designation, the value after the “x” identifies the section’s weight designation. The source also lists the unit weight separately in metric units.
What is the root fillet used for?
The root fillet describes the curved transition where the web meets the flange. It is important when coordinating connection plates, stiffeners, coping, and other details near that transition.
Is the W16x45 DWG ready for fabrication?
The linked DWG is a reference resource for drafting and coordination. Check its units, scale, geometry, and project-specific requirements before relying on it for fabrication or engineering documentation.
Does this page include every property needed for design?
No. This reference includes the values shown in the source content, but it does not provide every section property or design check needed for member and connection verification.
