  • A36 Steel Construction
  • ASTM A36 Certified
  • 36,000 PSI Yield Strength
  • Excellent Weldability
Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

A36 hot rolled steel angle is a low-carbon structural steel with a rough, scaled surface finish from its high-temperature forming process. Conforming to ASTM A36, it offers a dependable combination of strength, ductility, and superior weldability, often without preheating. This makes it a cost-effective choice for applications where precise tolerances are secondary to robust performance.

The substantial 4" x 4" leg dimensions and 1/2" thickness of this angle provide significant load-bearing capacity, making it ideal for heavy structural applications like building frames, main support members for industrial equipment, and heavy-duty trailer frames where maximum rigidity is required.

Specifications

  • Material: A36 Hot Rolled Steel
  • Standards: ASTM A36
  • Strength/Yield: 36,000 PSI (Minimum)
  • Dimensions: 4" x 4" x 1/2" x 240"
  • Finish: Hot Rolled (Mill Scale)
  • Certifications: MTR Available

Applications

  • Structural Engineering: Building frames and cross-members - high strength and weldability for primary supports.
  • Heavy Equipment: Machinery bases and skids - provides a rigid, durable foundation for industrial equipment.
  • Trailer Manufacturing: Main frame rails and chassis components - withstands heavy loads and road vibration.
  • Construction: Lintels over large openings and concrete form bracing - reliable structural support.

Target Users

Structural engineers, fabricators, and heavy equipment manufacturers rely on A36 angle for its strength and ease of fabrication in demanding applications throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled mill finish, characterized by a blue-gray, slightly rough surface scale. This scale must be removed before painting or coating for proper adhesion. For projects requiring corrosion resistance, galvanizing or other coatings can be applied after surface preparation. Contact our Los Angeles sales team for custom inquiries.

How to Measure

Steel angle is measured by its Leg (A) x Leg (B) x Thickness (C). For an equal leg angle like this one, both leg dimensions are the same. Measure with a tape measure or calipers.

Example: To order this angle, specify "A36 Angle, 4 inch by 4 inch by 1/2 inch thick".

Order Checklist

  • Product name and required dimensions (4" x 4" x 1/2" x 240")
  • Material specification and quantity
  • Confirm grade (A36) meets requirements
  • Surface finish requirements (Hot Rolled)
  • Certifications required (Mill Test Report)
  • Special handling or delivery requirements
