DBSTM50 ~ DBSTM100
The Steel monocell(DBSTM) is the product developed under combined merits of former monocell with new monocell the upper plate of rail joint is designed as Monocell shape and it is manufactured as one body or min 1m. The DBSTM has the same performance as the Single-Rail joints and has added a wave shape to the upper surface for increased driveability.
The waterproof rubber seal between rail beams is put in the rail groove processed in the same way as a rubber seal, playing its waterproof role perfectly.
The spacing between rail beams can accommodate 30 to 100 mm depending on site conditions.
• The same structure as single rail so it is applied to diversity bridges such as horizontal, longitudinal,transverse, skewed bridge and curved bridge.
• Full waterproof function
• Customized design
• Approved high-quality materials
• Material is semi-permanent.
• DBSTM is manufactured with a rubber seal as one body so the waterproof is excellent.
• The upper surface is the same shape as former monocell and the traffic ability is superior.
For the implementation of the perfect waterproof function of expansion joints, waterproof rubber seals are put in the rail grooves processed in the same way of rubber seals. So, water leak is perfectly prevented. It is easy to assemble and repair the diamond-shaped waterproof rubber seals that have the excellent function to prevent water from leaking to the bottom of an expansion joint.
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.

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.
