UTT BC3 is a standard structural connection component widely used for pipeline support and seismic bracing systems. It offers two material choices: high-strength carbon steel and high-toughness QT450 ductile iron. Two surface treatments including black raw steel and galvanized anti-rust finish are provided to suit various indoor and semi-outdoor working environments. The product fully complies with Federal Specification WW-H-171 (Type 23), ANSI/MSS-SP-58 (Type 19 & 23), and follows the installation regulations of ANSI/MSS-SP-69.
It has two mainstream sizes, 3/8"(M10) and 1/2"(M12), with complete standard dimensional parameters. This fitting is mainly used to fix pipeline support assemblies on metal beams, purlins, channel steel and angle iron of steel structure buildings. To ensure reliable load-bearing capacity and connection stability, the setscrew shall be fully tightened and torqued against the sloped surface of I-beams in actual installation.
Core Function: Connect pipeline supports to the top and bottom of metal beams, purlins, channel steel and angle iron for stable installation
Raw Material: Carbon Steel / QT450 Ductile Iron
Surface Finish: Black finish / Galvanized finish
Compliance Standard: WW-H-171(Type 23), ANSI/MSS-SP-58(Type 19&23), ANSI/MSS-SP-69
Available Sizes: 3/8"(M10), 1/2"(M12)
Installation Requirement: Torque the setscrew onto the sloped side of I-beam.

Carbon steel for cost-saving conventional projects; QT450 ductile iron delivers excellent toughness and impact resistance for heavy-load and seismic applications.
Black finish is suitable for dry indoor environments; galvanized finish provides long-lasting rust protection for humid working areas.
Classic standard size design, widely compatible with most common steel beams and installation spaces on the market.
UL and FM approvals satisfy strict acceptance rules for fire protection and international engineering projects.
Fits I-beams, purlins, channel steel and angle iron, covering most mainstream steel structural bases.
Unified operation rule for setscrew positioning effectively avoids loose connection and guarantees long-term operational safety.
