  • ASTM A500 Certified
  • 58,000 PSI Tensile Strength
  • Superior Corrosion Resistance (Zinc Coated)
Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

Galvanized square steel tubing is a carbon steel tube that has been hot-dipped in a protective zinc coating for a durable, abrasion-resistant barrier against rust. Manufactured to meet ASTM A500 Grade B specifications, it has a minimum yield strength of 46,000 PSI, suitable for load-bearing applications. This process combines steel's strength with long-lasting environmental protection, reducing long-term maintenance costs.

As a small-profile tube, this 3/4" size is ideal for lightweight structural and fabrication projects. Its strength-to-weight ratio makes it a preferred choice for gate frames, fence railings, trailer components, equipment frames, and agricultural structures like greenhouse frames where durability against the elements is a primary requirement.

Specifications

  • Material: A500-B Galvanized Steel
  • Standards: ASTM A500
  • Strength/Tensile: 58,000 PSI
  • Dimensions: 3/4" x 3/4" x 16 Gauge Wall x 24'
  • Finish: Galvanized (Hot-Dip Zinc Coated)
  • Certifications: Mill Test Report (MTR) available upon request

Applications

  • Fencing & Gates: Gate frames and fence posts - superior weather resistance prevents rust.
  • Construction: Light structural framing and supports - provides long service life in moist environments.
  • Agriculture: Greenhouse frames and livestock enclosures - resists corrosion from environmental exposure.
  • Trailers & Marine: Utility trailer frames and dock supports - durable zinc coating protects against road salt and water.

Target Users

Fabricators, construction contractors, ranchers, and trailer manufacturers rely on A500-B Galvanized Square Tube for durable, corrosion-resistant structures and components throughout the Los Angeles area.

Finish Options

This product comes standard with a hot-dip galvanized finish, which provides a thick, protective zinc coating for maximum corrosion resistance. The surface can be painted for aesthetic reasons, but must be properly cleaned and primed with a wash primer to ensure adhesion. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Square tube is measured by its outer dimensions (Width 'A' x Height 'B') and its wall thickness ('C'). Wall thickness is often specified as a gauge number.

Example: To order this square tube, specify "Galvanized Square Tube, 3/4 inch x 16 Gauge".

Order Checklist

  • Product name and required dimensions (3/4" x 16 Ga x 24')
