• Certification: Mill test report EN 10204 3.1, dimensional & plating inspection report provided.

Galvanized Coating: A robust layer of zinc protects the bolt from rust and corrosion, making them suitable for outdoor use and harsh environments.

U-Shaped Design: The U-shape allows for versatile applications, including securing pipes, beams, and other structural elements.

Threaded Ends: Both ends of the U-bolt are threaded, allowing for secure fastening without the need for additional components.

High Tensile Strength: Capable of withstanding high loads, these U-bolts are suitable for heavy-duty applications.

Precision Threads: Ensures compatibility with corresponding nuts and other fastening systems.

Construction Sites: Used to secure temporary structures, scaffolding, and heavy equipment in construction projects.

Industrial Settings: Employed in securing machinery, conveyor systems, and other industrial equipment that requires robust fastening solutions.

Agricultural Applications: Galvanized U-bolts are used to attach farming equipment, irrigation systems, and livestock fencing.

Automotive Repair: Utilized in the repair and maintenance of heavy vehicles and machinery for securing chassis and other components.

Infrastructure Projects: Secures electrical conduits, signage, and safety barriers in road and bridge construction.

Outdoor Facilities: Used in theme parks, sports facilities, and recreational areas for securing bleachers, fencing, and other structures.

Storage Racks: Galvanized U-bolts are ideal for assembling and securing storage racks and shelving systems in warehouses.

Piping Systems: Secures pipes and conduits in various piping systems, especially in outdoor or corrosive environments.

Solar Mounting: Used in the mounting of solar panels and related structures, providing a durable and weather-resistant fastening solution.

Marine Applications: Due to their corrosion resistance, these U-bolts are suitable for securing equipment and structures in marine environments.
