Carbon Steel Threaded Rod — Factory Direct Supplier | Huaxia-Steel
Huaxia-Steel is a factory-direct supplier of carbon steel threaded rod (stud bar / all-thread rod). Used for anchoring, tensioning, and fastening, our threaded rod is rolled or cut to precise thread standards and supplied in plain, zinc-plated, or hot-dip galvanized finishes. Grades include A36, 1018, 1045, Q235, and 4.8/8.8 property classes, with mill test certificates on request.
Product Overview
A threaded rod is a continuous-length bar with threading along its full length (or partial length). It functions as a tension member, anchor bolt, or adjustable fastener. We offer both rolled-thread (stronger, grain-flow maintained) and cut-thread production depending on diameter and grade.
