The W33x387 is a wide-flange structural steel section listed in the W-shape reference data below. This page brings together its reported geometry, sectional area, unit weight, and a downloadable DWG file for drafting workflows.
Use the dimensional information as a reference when reviewing W-shape steel sections, comparing section sizes, or coordinating structural drawings. Final member selection, connection design, stability checks, and material verification must be completed by a qualified engineer using the applicable project requirements.
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 : 914.4 mm
Width : 411.5 mm
Web Thickness : 32 mm
Flange Thickness : 57.9 mm
Root Fillet Radius : 20.1 mm
Sectional Area : 735.48 cm2
Unit Weight : 577.4 kg/m
How to read the W33x387 reference data
The listed properties describe the section’s overall geometry and basic quantity information. Depth and width describe the principal envelope dimensions. Web thickness and flange thickness identify the thicknesses of the central web and projecting flanges, while the root fillet radius describes the transition between those parts of the rolled shape.
Sectional area is useful for material-quantity calculations and for interpreting section-property references. Unit weight supports estimating steel mass and reviewing fabrication or shipping information. These values should be read together with the project’s material specification, fabrication tolerances, connection details, and design checks rather than used as a stand-alone design decision.
Drafting and design coordination
The downloadable DWG can help users place the section profile into CAD drawings, connection details, framing plans, and coordination models. Before issuing drawings, confirm the insertion scale, units, layer standards, orientation, and any local drafting conventions. The profile geometry does not by itself define bolt layouts, welds, copes, stiffeners, bearing conditions, or other connection requirements.
For broader context, compare this entry with other steel section properties and review related structural steel connection concepts. The source identifies AISC 360-16 as the governing reference context for the supplied information; users should verify the edition and project applicability before relying on it for design or detailing.
W33x387 FAQ
What type of section is W33x387?
W33x387 is identified here as a W beam, also called a wide-flange structural steel section.
What information is provided for W33x387?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. The page also provides a DWG download for CAD use.
Can the W33x387 DWG be used directly for structural design?
The DWG is a drafting reference for the section profile. It does not replace engineering calculations or define the complete requirements for member design, connections, fabrication, erection, or project-specific detailing.
Which reference context is identified on this page?
The supplied source refers to AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings. Confirm the applicable project requirements and reference edition before use.
