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

Hot rolled rectangular steel tubing is a structural product manufactured to the robust ASTM A500 Grade B specification. The hot rolling process delivers excellent forming and welding characteristics with a scaled, rougher surface finish. Its combination of high tensile strength, torsional resistance, and cost-effectiveness makes it a foundational material for construction, fabrication, and industrial manufacturing projects requiring significant load-bearing capacity.

As a large, heavy-wall profile, this 6" x 4" x 0.375" tube is ideal for applications subject to high stress and twisting forces. Common uses include structural columns, building frames, heavy equipment bases, trailer mainframes, and industrial support systems where strength and rigidity are critical design requirements.

Specifications

  • Material: A500B Hot Rolled Steel
  • Standards: ASTM A500 Grade B
  • Strength/Tensile: 58,000 PSI
  • Dimensions: 6" Width x 4" Height x 0.375" Wall x 20' Length
  • Finish: Hot Rolled Mill Finish
  • Certifications: Mill Test Report (MTR) Available

Applications

  • Construction: Heavy structural frames, support columns, and trusses - Provides high load-bearing capacity.
  • Trailers & Automotive: Heavy-duty trailer frames, cross-members, and tongues - Resists severe bending and torsional stress.
  • Industrial Machinery: Machine bases, press frames, and conveyor systems - Excellent for absorbing vibration and supporting heavy loads.
  • Racking & Storage: Main supports for heavy-duty warehouse racking and mezzanine systems - Resists compression.

Target Users

Structural engineers, heavy equipment manufacturers, professional fabricators, and construction contractors rely on A500B rectangular tube for its strength and reliability in demanding applications throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled mill finish, characterized by a dark, scaly surface. This scale must be removed by grinding, sandblasting, or pickling before painting or powder coating. It can be left unfinished for indoor use where corrosion is not a concern. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Rectangular tube is measured by its Outer Width (A), Outer Height (B), and Wall Thickness (C). Use a tape measure for width and height and calipers for an accurate wall measurement.

Example: To order this tube, specify "6 inch by 4 inch by 0.375 inch wall Hot Rolled Rectangular Tube".

Order Checklist

  • Product name and required dimensions (6" x 4" x 0.375")
  • Material specification and quantity (in feet or number of 20' lengths)
  • Confirm grade (A500B) meets structural requirements
  • Surface finish requirements (Standard Hot Rolled)
  • Certifications required (Mill Test Report)
