A36 Steel I-Beam - 3" x 2.509" x 20'

A36 hot rolled steel I-beam with a 3" height, 2.509" flange, and 20 ft length. Conforming to ASTM A36, this beam provides a minimum yield strength of 36,000 PSI and excellent weldability, making it ideal for structural frames and equipment bases. In stock Los Angeles.

  • A36 Carbon Steel Construction
  • ASTM A36 Certified
  • 58,000-80,000 PSI Tensile Strength
  • Excellent Weldability and Formability
Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

This A36 steel I-beam is produced through a hot rolling process, giving it excellent ductility and toughness. As a low-carbon structural steel, it conforms to ASTM A36 standards and guarantees a minimum yield strength of 36,000 PSI for predictable performance under load. The 'I' cross-section is highly efficient for resisting bending and shear forces, making it a cornerstone of general construction and fabrication.

As a medium-sized structural member, this 3-inch I-beam is perfectly suited for equipment bases, building frames, mezzanine floor joists, and trailer chassis where a balance of robust strength and manageable weight is crucial for project success. Its versatility makes it a go-to choice for fabricators and contractors.

Specifications

  • Material: A36 Carbon Steel
  • Standards: ASTM A36
  • Strength/Tensile: 58,000 - 80,000 PSI
  • Dimensions: 3" Height x 2.509" Flange x 0.349" Web x 20' Length
  • Finish: Hot Rolled (Mill Scale)
  • Certifications: Mill Test Report (MTR) Available

Applications

  • Industrial Equipment: Machinery bases and support frames - for high rigidity and vibration damping.
  • Construction: Mezzanine floor joists and roof trusses - for reliable load-bearing capacity.
  • Transportation: Trailer frames and chassis cross-members - offering durability and structural strength.
  • Material Handling: Hoist supports and light-duty crane runway beams - to safely resist dynamic loads.

Target Users

Fabricators, construction contractors, and machine builders rely on A36 I-Beams for structural integrity in commercial and industrial projects throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled finish, characterized by a dark, scaly surface. This mill scale can be removed by grinding or sandblasting prior to painting, powder coating, or galvanizing for corrosion protection. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

An I-Beam is defined by its Height (the overall vertical dimension), Flange Width (the width of the top and bottom horizontal sections), and Web Thickness (the thickness of the central vertical section).

Example: To order this I-Beam, specify "A36 I-Beam, 3" height x 20' length".

Order Checklist

  • Product name and required dimensions (3" Height x 20' Length)
  • Material specification and quantity
  • Confirm grade (A36) meets engineering requirements
  • Surface finish requirements (Hot Rolled)
  • Certifications required (Mill Test Report)
  • Special handling or delivery requirements
