ROHN 5' Steel Tubing - 16 Gauge Steel Mast Pipe with Locking Joints (Rohn 160505GHS) **This listing is for (1) section of tubing only - the picture is of 2 sections to show each end of the pipe** HOT-DIP GALVANIZED STEEL TUBING FOR ANTENNA MOUNTING. ROHN PART NUMBER : 160505GHS 1-1/4" OD x 16 Gauge x 5' Long - swaged one end (creates a locking joint when 2+ sections are joined together) When tubing is swaged, the metal is compressed and made thicker so that the joint is stronger than the original material. Swaging also eliminates the "joint bulge" common with expanded tubing. ROHN's hot-dip galvanized tubing is fabricated from high-strength steel, then immersed in molten zinc giving all surfaces, including the interior, an even coating of zinc for maximum corrosion protection. There are no seams, holes, or edges left uncoated
