Product Overview
Our Beam Clamps (also widely known as C Clamps, Purlin Clamps, or Malleable Iron Clamps) are heavy-duty fasteners designed to clamp onto the flange of steel beams (I-beams/H-beams) without drilling or welding. They provide a secure mounting point for Threaded Rods to suspend heavy loads such as pipes, sprinkler systems, and HVAC ducts.
Russian Name: Струбцина монтажная / Зажим для балки / Лучевой зажим
Material: Malleable Iron (Cast Iron) or Carbon Steel
Key Features
-
No Drilling Required: Clamps directly to the beam flange, maintaining the structural integrity of the steel beam.
-
High Load Capacity: The hardened set screw ensures a bite-tight grip on the beam.
-
Versatile: Compatible with standard M6, M8, M10, and M12 threaded rods.
-
Corrosion Protection: Zinc Plated (ZP) finish for long-lasting rust resistance in indoor environments.

Why Partner with HDBolt for Beam Clamps?
Casting Expertise Our Beam Clamps are manufactured using high-grade Malleable Iron casting techniques in our specialized foundry. Unlike cheaper brittle iron, our malleable iron undergoes a strict annealing process, giving the clamp the toughness and ductility needed to withstand heavy structural loads without cracking.
Strict Testing Safety is critical for overhead suspension. We conduct torque testing on the set screw to ensure it bites into the steel beam flange securely without stripping. We also perform load-bearing tests on random samples from every batch to verify they meet the Safe Working Load (SWL) requirements.
Global Standards Our products are designed to meet the dimensional and performance requirements of MSS SP-69 (Type 19 & 23) standards. Whether you are supplying a project in Moscow or St. Petersburg, our clamps fit perfectly with standard metric threaded rods and beam flanges.
Fast Export We keep a safety stock of 50,000 pcs for M8, M10, and M12 sizes. This allows us to consolidate these small heavy items with your Strut Channel or Threaded Rod orders in the same container, saving you LCL shipping costs.
