INDUSTRIES

As a key connector in bridge engineering, anchor bolts play a core role in structural reinforcement, component installation, seismic design, etc.
The products of Tedun Fastener Group are widely used in bridge construction due to their high strength, corrosion resistance and fatigue resistance.

Anchor bolts are the "invisible bones" of the curtain wall, using high-strength anchoring force to resist wind loads and seismic displacement, and ensure corrosion-resistant safety for more than decades.

The application of fasteners in mechanical equipment is fundamental, extensive and critical. They are the "skeletal connectors" of mechanical structures and are directly related to the assembly accuracy, operational reliability, load-bearing capacity, service life and safety of the equipment.

Nuclear power fasteners are a model of "small parts with great safety", and their technological breakthroughs directly support my country's nuclear power independence strategy. With the advancement of anti-loosening structure innovation (such as mechanical locking studs), special manufacturing processes (rotational uniform tempering) and domestic substitution (shear nails, sealing sleeves), nuclear power fasteners are developing towards higher safety, longer life and intelligent monitoring.

Fasteners play a key role in the photovoltaic industry. They are mainly used for the fixed connection of photovoltaic support systems and components.
Their performance and reliability directly affect the safety, durability and power generation efficiency of power stations.

Pipeline corridor fasteners have been upgraded from basic connectors to safety-critical subsystems, and their development focuses on three major directions:
Precision performance: innovative structures for pain points such as large-diameter pipeline deformation (such as three-section piers) and dynamic loads (seismic bolts);
Efficient installation: adjustable joints and embedded channels promote assembly rates and shorten construction periods by 30%~50%
Full-cycle cost control: corrosion-resistant materials and intelligent monitoring reduce operation and maintenance costs.

Fasteners are small, but they are ubiquitous and indispensable "safety guards" in the huge rail transit system.
They silently bear extreme loads and harsh environments, maintaining the structural integrity and functional reliability of key systems such as vehicles, tracks, power supply, and signals.
The rail transit industry has much higher performance requirements for fasteners than the general industrial field. Their selection, manufacturing, installation, and maintenance all follow extremely
strict standards and specifications (such as EN, DIN, ISO, GB, TB, etc.), which is an important cornerstone for ensuring passenger safety and efficient system operation

The role of fasteners in steel structures has evolved from "basic connectors" to "safety-critical components".
Future technologies will focus on corrosion-resistant materials (such as nitride coatings), intelligent monitoring (IoT bolts) and installation process innovation (robotic tightening systems) to cope with extreme load and life requirements in scenarios such as super-high-rise buildings and offshore wind power.
