Settlement Monitoring Rod

Kingmach Measurement & Monitoring Technology Co., Ltd. focuses on devices that track ground behavior. Settlement monitoring rods are one of several hundred products we manufacture for geotechnical and structural monitoring. The rod itself is simple in concept – a vertical reference line installed in a borehole or fill – but the details matter when readings are taken over years. Threaded connections can loosen, steel couplings can corrode, and a rod that bends under lateral soil pressure will introduce error. For that reason we double-check thread fit on every coupling and coat threaded joints with anti-seize compound before packing. Stainless steel rods are electropolished in-house to reduce friction inside the guide casing. When a job calls for a rod longer than three meters, we segment it with internally threaded joints that keep the rod's outer surface smooth so it doesn't catch on the borehole liner. We also supply settlement rods for inclinometer casing installations, where the rod sits alongside the casing and provides a fixed datum for settlement measurements. In those setups, the rod material must match the thermal expansion characteristics of the inclinometer string to avoid differential movement in temperature swings. Our engineers can advise on material matches if you send general site conditions. For remote monitoring, magnetic ring targets can be added at specified intervals; these work with Reed switch probes to give depth-settlement profiles. All rods are shipped with protective end caps, and custom packing crates are built for sea freight when needed. Technical support is part of every order. Whether you need help deciding between galvanized and stainless, or advice on grout backfill that won't chemically attack the rod, a geotechnical engineer from our team is available for consultation. We ship from warehouses in Asia, Europe, and North America, so local stock is often possible for standard lengths. If not, production lead time is typically two weeks from drawing approval. Because our plant handles everything from cutting and threading to final QC, we don't depend on third-party suppliers for specialty orders – that keeps the chain short and reliable.
