Key Features

1. Summary

The Finger type expansion joint(DBF) is a commonly used type of expansion joint for bridges. It is composed of multiple ""finger"" shaped elements that are designed to accommodate structural displacement. These elements are interconnected to absorb the stress and deformation that occur at the expansion joint of the bridge.

2. Features

The finger plate absorb the impact and vibrations generated by the passage of vehicles, thereby reducing noise. Due to these characteristics, the Finger type expansion joint(DBF) plays a crucial role in enhancing the safety and travel quality of bridges. The waterproof rubber seal is fixed to the underside of the finger plate with bolts, providing waterproofing and allowing for replacement when necessary. The allowable displacement ranges from a minimum of 50mm to a maximum of 500mm.
• The main components are made of thick steel, ensuring excellent durability.
• Customized design
• The finger plate are detachable in 1-meter sections, making maintenance easier.
• DBF can be applied to straight bridges as well as curved bridges.
• DBF is easy to install and provides good drivability.
• Cost-effective.
• Approved high-quality materials

3. Anti-corrosion

As for the surface treatment of structural steels, hot dip galvanizing is applied to prevent salt stress and corrosion in accordance with KS D 8308 Standards. Compared to coating, this treatment guarantees excellent corrosion-resistance and adhesion. The thickness is 85μm, ensuring about 45 years of endurance.

Warranty Period

2 years after product installation

Company Overview

Daebong B.m.tech, which was established on the belief that we can replace overseas products with our owns by our technology, has been investing intensively on R&D. With these efforts, it has been nominated as a Technology Innovation Company and acquired US Steel Structure Certification, becoming an international technology leading company.
The expansion joint on bridges is our main product, and it's a core equipment that secures bridge safety which endures the gap movement occurred by the expansion and the contraction in the bridge deck.
Continuous technology development, superior product quality, and safety first policy. Under these three core values, our products have been installed in about 1000 bridges including Incheon Bridge and Busan Harbor Bridge based on the 10,000 meters of annual production capacity and 99% of quality test passing rates.
As a company which is trying hard to be the first and the best, we are exporting the bridge Expansion Joints developed with an introduction of the Load and Resistance Factor Design overseas for the first time in Korea.
