Galvanized square tube has three actual0.5–6mm wall-range pairings with6m,6.4m and12m. Exact section geometry and material need confirmation.

Choose actual dimensions

Body wall2–10mm and length5.8–12m are family references. Specify legs, bore and wall rather than replacing the actual option range.

• Square Shape identity.
• 10×10/15×15/20×20mm references.
• Galvanized surface.
• Custom sections described.
• ±1% tolerance reference.

Define coating evidence

Zinc-layer2.5–15μm is a technical reference requiring actual measurement. Hot-dip title wording needs supplied-process confirmation.

Agree engineering acceptance

Request actual grade, dimensions and coating tests. Structural/fluid contexts do not establish load capacity, pressure rating or corrosion life without selected-tube and project inspection records. Clarify zinc measurement location and inspection acceptance for the chosen tube.
