To purchase the eight-edge monitoring rod, select several manufacturers with moderate prices. We need to investigate the materials used. Generally, the materials for making monitoring rods are galvanized steel pipe and stainless steel pipe, among which galvanized steel pipe has cold galvanized and hot-dip galvanized point. The price from high to low is stainless steel pipe > hot-dip galvanized steel pipe > cold galvanized steel pipe. Secondly, look at the workmanship of the eight-edge monitoring rod. The welding size should meet the design requirements, the welding wave on the metal surface of the weld should be uniform, and there should be no cracks and needle-shaped pores that affect the strength. The thickness of hot-dip galvanizing shall not be less than 85um for anti-corrosion treatment, and the zinc layer shall be smeared evenly. In addition, each manufacturer has different wall thicknesses for the eight-edge monitoring rods of the same height. When purchasing, you should ask clearly. If you have special requirements, you can inform the manufacturer to customize.
