The W27x84 page provides a concise reference for a W beam, including its listed dimensions, section area, unit weight, and CAD download. Use the technical values below as the controlling local reference for drafting, estimating, and preliminary engineering review.
For design work, confirm material requirements, load effects, connection details, stability conditions, and applicable project criteria with the responsible engineer. The section data alone does not establish whether a member is adequate for a particular application.
W Beam

How to use this W27x84 reference
The source data identifies the principal geometric characteristics of the section, including depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These properties support common steel detailing and coordination tasks, while design calculations require additional checks beyond the dimensions shown here.
Reading the section data
Depth and width describe the overall envelope used when coordinating framing, clearances, and drawings. Web and flange thicknesses help distinguish the section geometry and may be relevant to connection detailing and fabrication review. The root fillet radius is important when a detail interfaces with the rolled shape, especially where plates, angles, or connection components meet the flange and web.
Weight and material takeoff context
The listed sectional area and unit weight are useful for comparing W-shape references and preparing preliminary material takeoffs. Final quantities should account for the complete framing arrangement, connection materials, cuts, coping, stiffeners, and project-specific fabrication information.
DWG reference
The downloadable DWG can support drafting and model coordination. Treat CAD geometry as a reference resource, and verify critical dimensions against the authoritative section data before fabrication or construction use.

W27x84 frequently asked questions
What type of section is W27x84?
W27x84 is identified on this page as a W beam reference. The page’s source content provides the section geometry, sectional area, unit weight, and associated DWG file.
What is the AISC reference on this page?
The source refers to AISC 360-16, the AISC Specification for Structural Steel Buildings. It provides the design, fabrication, and erection framework identified in the original content.
Can the DWG be used directly for fabrication?
The DWG is intended as a drafting and coordination reference. Verify its geometry and all fabrication-critical details against the project documents and authoritative section data before releasing fabrication information.
Does the listed section data prove that W27x84 is adequate for a structure?
No. Member adequacy depends on loading, span, unbraced conditions, material, connections, stability, and other project requirements. A qualified engineer must complete the applicable design checks.
