These high-strength carbon steel masts are cold-drawn and electric-welded with a specified yield stress rating of over 100,000 psi! Tensile strength minimum is above 110,000 psi. Minimum Rockwell B hardness is 96. They are temperature stress-relieved to ensure consistent mechanical strength. Heavy-Duty 4130 Chromoly Steel Mast is a far stronger choice as compared to a typical galvanized plumbing pipe.

Galvanizing on these masts meets ASTM A123/A123M specifications. The surface finish gleams brightly and has a nearly polished appearance. However, surface irregularities are to be expected on these galvanized masts and cut ends are sprayed with cold galvanizing coating.

Are you planning on stacking a few mono-banders on the tower? Are you going to have multiple Yagis stacked high and deep on an H frame? Are you raising a BIG log-periodic? If you are going to loft big antennas with a lot of wind area, then you absolutely need a DXE Heavy-Duty 4130 Steel Mast atop your heavy-duty tower!
