All thread rod is manufactured in 3 ways: mass-produced, cut-to-length, and cut thread. Common grades and diameters are mass produced and available across the country. Cut-to-length all thread rod uses mass-produced rods which are then cut to the finished length with the ends chamfered. Cut thread all thread rod is manufactured for special grades of steel that are not mass produced. These rods are cut slightly longer than the finished length, fully threaded, then cut to the finished length and chamfered on each end. For all manufacturing styles, the all thread rod can then be galvanized or coated per the customer’s requirements
