1. Structural Efficiency

Bulldog spike rings enable connections to be designed using fewer tie bolts, allowing for proper spacing between bolts and from the wood edges. This increases the stability and security of the structure while reducing the risk of material damage.

2. Versatile Applications

The product is available in double-sided versions for timber connections and single-sided versions for timber-to-steel connections, making it suitable for a variety of structures and materials, including solid timber, composite timber, and laminated timber.

3. Anti-corrosion protection

The steel used to produce the rings is hot-dip galvanized (50 µm), which provides excellent corrosion protection and extends the product's life even in harsh weather conditions.

4. Durability and connection strength

Bulldog barbed rings provide strong and durable connections, which is crucial in structural elements requiring high load-bearing capacity. They also enable easy disassembly, which further increases the functionality and practicality of use in various construction and renovation projects.

5. Service class

Characterized by material moisture corresponding to a temperature of 20°C and relative humidity of the surrounding air exceeding 85% only for a few weeks a year.

6. Zinc coating

The products are immersed in molten zinc at 550-560°C. The zinc coating is formed by a reaction between the steel component and the zinc, and forms on both sides of the immersed component. It provides good corrosion resistance in most environments.

Application and method assembly

• Used to connect timber to steel members to increase the load-bearing capacity of the bolted connection in structural elements.

• Installation is carried out using a hydraulic press or a wooden block and a hammer.

• If the toothed ring is assembled in a workshop, 1 or 2 nails may be needed to hold it during transport.

• DoP- h10/0007

• EN 145454: 2008
