The W30x357 is a wide-flange structural steel beam designation with dimensional and section-property data reported in the reference below. Use this page to identify the section, interpret each listed property, and access the associated DWG file for drafting workflows.
The source data is presented in metric units and is referenced to AISC 360-16. For related terminology, compare this entry with guides to W-shape dimensions, steel section properties, and AISC shape nomenclature.
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.

How to read the W30x357 reference
The designation identifies a W beam, while the reference data describes its overall geometry and material quantity. The listed depth and width help establish the section envelope for drawings and coordination. Web thickness, flange thickness, and root fillet radius describe important portions of the rolled shape and may matter when checking clearances, detailing connections, or coordinating adjacent components.
Section properties and weight
Sectional area describes the steel area through a transverse cut of the member. The reported unit weight indicates the listed weight per unit length and can support material takeoffs, shipping estimates, and preliminary coordination. These values should be used with the governing project requirements and verified against the applicable design, fabrication, and detailing workflow.
Reference and CAD use
The source identifies the AISC Specification for Structural Steel Buildings (AISC 360-16) as its reference. This page is a dimensional reference rather than a complete design check: member selection, strength, stability, connections, fire requirements, and serviceability require qualified engineering review.
The downloadable DWG can be useful for drawing setup and layout. Before incorporating it into a project, confirm units, layer conventions, file integrity, and the required level of detailing. Related resources on steel connection detailing and CAD/DWG steel shapes can help place the section data in a broader drafting workflow.
W30x357 FAQ
What type of section is W30x357?
W30x357 is identified in the source as a W beam, also called a wide-flange structural steel section.
What information is listed for W30x357?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. The values are provided in metric units in the source content.
Which specification is referenced?
The source refers to the American Institute of Steel Construction Specification for Structural Steel Buildings, AISC 360-16.
Can the W30x357 DWG be used directly for structural design?
The DWG is a drafting reference and does not replace engineering verification. Confirm the geometry, project requirements, material specification, connection design, and applicable checks before using the section in a project.
