1. Product Overview

This industrial 3/8" electro-galvanized I-beam beam clamp (also known as a beam clamp, C-clamp adapter, steel beam clamp or beam clip) is engineered for use with 3/8 inch (3/8"-16) all-thread rod. It carries a working load limit (WLL) of 400 lbs (approx. 180 kg). As an efficient mechanical fastener, it clamps quickly onto the flanges of I-beams, channel steel or H-section steel without welding or drilling.

The body is precision cast from high-strength malleable iron. A top set screw with hex lock nut clamps the flange inside the jaw, providing a secure structural support point for threaded rod, suspension rings and pipe or conduit hanger systems below the beam.

2. Product Features

  • Standard 3/8" rod interface and 400 lbs WLL: Sized for 3/8 inch suspension rod with a rated working load of 400 lbs—meets safe capacity needs for light to medium industrial and building suspension systems.
  • Non-destructive installation: No holes, welds or other permanent changes to the beam or building structure. Simple to install and remove while preserving original steel strength and protective coatings.
  • High-strength bite and anti-loosening design: Hardened set screw tip bites firmly into the flange for strong anti-slip grip. Hex lock nut secures the bolt after positioning to help prevent loosening from building vibration or equipment operation.
  • Heavy cast structure: Thick jaw walls and robust malleable iron casting resist cracking and plastic deformation under long-term suspended loads.
  • Full electro-galvanized finish: Dense zinc plating resists rust, corrosion and oxidation—suited to industrial plants, underground utility corridors and general building environments.

3. Product Advantages

  • Defined WLL 400 lbs rating for engineering compliance
  • No drilling or welding—pure mechanical clamping reduces site risk and labor cost
  • Fast installation with common hand tools—one person can complete mounting
  • Durable electro-galvanized coating for long service in indoor and industrial settings
  • Removable and repositionable for adjustment and future pipeline maintenance

4. Application Scenarios

Widely used in steel-framed buildings, industrial plants and MEP installation as a key connection node for suspension and support systems:

  • Building MEP engineering: Fire sprinkler piping, HVAC ductwork, plumbing lines and integrated utility suspension.
  • Electrical and lighting: Cable tray, cable channel, conduit support, industrial lighting and distribution panels.
  • Steel-framed buildings: Industrial plants, warehousing and logistics centers, commercial complexes, steel platforms and mezzanines.
  • Industrial facilities and utility corridors: Pipe support frames, 3/8" all-thread rod suspension, signage and suspended ventilation equipment.
