American Standard W Beam Sizes Chart (W4x13 to W44x335) – Complete Guide

American Standard W Beams, also known as Wide Flange Beams, are the backbone of modern structural steel construction. However, with dozens of standard sizes available, finding the exact specifications you need can be time-consuming. This guide simplifies your search by consolidating the most common W beam sizes into an easy-to-browse chart, complete with expert insights to help you make an informed selection quickly.

• Popular Sizes: [W8x24] | [W10x33] | [W12x50] | [W14x90] | [W16x100] | [W18x119] | [W21x111] | [W24x94] | [W27x114] | [W30x116] | [W33x141] | [W36x135]

How to Find Your Size Quickly in This Guide

Pro Tip: Use your browser’s Find function (Ctrl+F or Cmd+F) and type the specific shape you need (e.g., “W12x50”) to instantly locate it in the chart below.

Every W beam is designated by a unique code. For example, in W12x50:

• W stands for “Wide Flange.”
• 12 is the nominal depth in inches.
• 50 is the weight in pounds per foot.

Complete W Beam Sizes and Dimensions Chart

Below is a pre-sorted list of the most common and representative W beam sizes. All dimensions are in inches, and weight is in pounds per foot.

Chart data is based on the AISC Steel Construction Manual for commonly used ASTM A992 material. While we strive for accuracy, always consult official specifications for critical applications. For specific size requirements, IBC Group can provide custom-cut beams to your exact specifications.

How to Select the Right W Beam: An Expert Breakdown

1. By Application: Common Sizes and Their Uses

• W8x10 – W8x24: Ideal for light structural framing, purlins, and girts.
• W12x50 – W12x65: A popular and versatile choice for floor beams and medium-span girders in commercial buildings.
• W14x90 – W14x120: Frequently specified for heavy columns and primary girders due to their robust cross-section.
• W21x44 – W21x62: Excellent for long-span floor beams and roof members, offering a great balance of depth and strength.

2. Key Selection Factors

• Load and Span: Heavier and deeper sections (like W36x135) are designed to carry greater loads over longer distances.
• Dimensional Constraints: Always check the Depth (d) and Flange Width (bf) to ensure the beam fits within your architectural and mechanical space limits.
• Material and Cost: ASTM A992 is the modern high-strength standard. For a precise cost comparison and availability check for your project, requesting a quote is the most reliable method.

FAQ

Q: What is the difference between a W Beam and an I-Beam?

A: While both have an “I” shape, W Beams (Wide Flange) have wider, thicker flanges and are the modern standard for structural frames. The term “I-Beam” often refers to older S-shape beams, which have narrower, tapered flanges.

Q: What does ‘ASTM A992’ mean for W beams?

A: ASTM A992 is the prevailing standard for high-strength, low-alloy structural steel shapes. It offers a superior minimum yield strength (50,000 psi) and excellent weldability compared to older grades like A36.

Q: Can you supply certified W beams with mill test reports?

A: Absolutely. We provide full material traceability. Certified mill test reports (MTRs) confirming chemical composition and mechanical properties are available and supplied with your order.
