Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

Hot rolled rectangular steel tubing is a structural product manufactured to the ASTM A500 Grade B specification. The hot rolling process results in a material with excellent forming characteristics and weldability, though with a scaled surface finish. Its combination of strength and cost-effectiveness makes it a foundational material for construction and industrial fabrication requiring robust, load-bearing performance.

As a large-profile tube, this 4" x 1-1/2" size provides significant resistance to bending and torsion, making it ideal for heavy structural applications like building frames, trailer beds, support columns, and industrial equipment bases where maximum strength is required.

Specifications

  • Material: A500 Grade B Hot Rolled Steel
  • Standards: ASTM A500
  • Strength/Tensile: 58,000 PSI
  • Dimensions: 4" Width x 1-1/2" Height x 0.188" Wall
  • Finish: Hot Rolled (Mill Scale)
  • Certifications: MTR Available

Applications

  • Construction: Building frames and trusses - High strength-to-weight ratio for load-bearing structures.
  • Trailers & Automotive: Trailer frames and cross-members - Resists bending and torsional stress under heavy loads.
  • Industrial Machinery: Machine bases and heavy equipment supports - Provides a stable and strong foundation.
  • Racking & Storage: Heavy-duty warehouse racking systems - Resists compression and supports significant weight.

Target Users

Fabricators, welders, construction contractors, and trailer manufacturers rely on A500B rectangular tube for its structural integrity and ease of fabrication in projects throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled mill finish, characterized by a dark, scaled surface. This scale must be removed by grinding or sandblasting before painting or powder coating for proper adhesion. Contact our Los Angeles sales team for custom finish inquiries like galvanizing or painting.

How to Measure

Rectangular tube is measured by its Outer Width (A), Outer Height (B), and Wall Thickness (C). Use calipers for accurate measurement of all three dimensions.

Example: To order this tube, specify "Hot Rolled Steel Rectangular Tube, 4 Inch x 1-1/2 Inch x 0.188 Inch Wall".

Order Checklist

  • Product name and required dimensions (4" x 1-1/2" x 0.188")
  • Material specification and quantity
  • Confirm grade (A500B) meets requirements
  • Surface finish requirements (Hot Rolled Mill Finish)
