India's Reliable Threaded Rod Exporter — Lengths to 6m, Grades to Grade B7
TERNS EXIM exports a complete range of threaded rods and studs from Coimbatore, India to construction, infrastructure, and industrial buyers globally. Our threaded rods comply with DIN 975 (full thread), DIN 976 (stud bolts with defined thread length), ASTM A193 (alloy-steel and stainless steel bolting for high-temperature and high-pressure service), and ASTM A307 (carbon steel bolts and studs).
Available in diameters M6 to M100 and lengths from 1000 mm to 6000 mm (in standard 1m and 2m cuts, or custom), threaded rods are essential for anchor bolt extensions, hanging systems, all-thread rod assemblies, structural tie rods, and general assembly work. All shipments include Mill Test Certificates and conform to specified dimensional standards.
