EN14399-10 HRC Tension Control Structural Bolts Manufacturing Process

EN14399-10 HRC Structural Bolts Application:

EN 14399-10 HRC Structural Bolts are high-strength preloaded fastening assemblies designed for steel structures

requiring reliable and consistent preload. Their tension control installation system ensures accurate clamping

force and improves structural safety.

1. Steel Building Structures

HRC structural bolts are widely used in steel frame buildings, warehouses, industrial plants, and commercial buildings. The controlled preload helps maintain the integrity of beam-to-column and column-to-column connections. Applications include: Industrial buildings/Commercial steel structures/Warehouses/Multi-story steel buildings

 

2. Bridge Construction

Bridges require high-strength bolted connections that can withstand dynamic loads, vibration, and fatigue. EN 14399-10 HRC bolts provide reliable preload and long-term structural performance. Typical applications: Steel highway bridges/Railway bridges/Pedestrian bridges/ Bridge rehabilitation projects

 

3. Power Transmission Towers

Transmission towers and substations require secure structural connections that can resist wind loads and environmental conditions.

HRC bolts are commonly used in: Transmission towers/Substation steel structures/Electrical support structures

 

4. Wind Power Projects

Wind turbine towers experience continuous dynamic loading and vibration. EN 14399-10 bolts

provide consistent clamping force, making them suitable for:

Wind tower steel structures/Turbine support frames/ Renewable energy projects

 

5. Industrial and Petrochemical Facilities

Heavy industrial facilities require high-strength structural connections capable of handling large loads and harsh environments.

Applications include: Oil and gas plants/Petrochemical facilities/Mining structures/Heavy equipment support structures

Key Advantages for These Applications

• High strength Property Class 10.9
• Controlled preload installation
• Reduced installation errors
• Excellent fatigue resistance
• Reliable structural performance
• Suitable for critical bolted connections
