Applications

  • Structural steel and square tubing are fundamental in commercial and residential construction for building frames, supports, handrails, and gates
  • Galvanized tubing is essential for outdoor structures like fencing, agricultural equipment, utility poles, and marine applications due to its rust resistance
  • Aluminum square tubing is widely used in automotive frames, aerospace components, lightweight trailers, furniture framing, and architectural features like sunshades and curtain walls where corrosion resistance and weight savings are paramount
  • Fabricators rely on our tubing for custom machinery, workbenches, and industrial equipment
  • Artists and designers also utilize our tubing for sculptures and functional art pieces, taking advantage of its formability and clean lines

Weldability

  • Welds readily by MIG, TIG, Stick, or Flux-core processes
  • Select filler based on section thickness and requirements

How to Measure

To ensure you order the correct tubing, measure carefully. For square or rectangular tubing, measure the outside dimensions (width and height) across the flats. For round tubing like 3 inch steel tubing, measure the outside diameter (OD). Wall thickness is critical; use calipers to measure the thickness of the tube wall itself. Specify the material type, shape, exact dimensions (e.g., 3x3x0.25 inch for square, or 3 inch OD with schedule for round), and desired length. The experts at Bobco Metals in Los Angeles are always available to assist with measurement verification and product selection for your specific application.

Order Checklist

  • Product specification and required dimensions
  • Grade (e.g., 6061-T6) and quantity needed
  • Length requirements (standard or custom cut-to-size)
  • Surface finish requirements (as-rolled, cleaned, primed)
  • Any certifications (Mill Test Report - MTR) for traceability
  • Special handling or packaging needs
