Expansion device "Metal Garg Joint NT-FFLDZ type"
NT-FFLDZ type (hot-dip galvanized specification)
Melted zinc plating specifications! Contributing to daily environmental maintenance with performance and price.
The "Metal Garg Joint NT-FFLDZ Type" is an expansion device for bridges and elevated roads that reduces vibrations and noise through its double-sided tooth profile, which mitigates impact during vehicle passage, and the use of excellent soundproofing filling materials. The anchor components utilize a bar method with stud welding, making the installation of the floor slab secure and easy. Special formwork for installation is not required, which shortens construction time. Due to its structure that encapsulates the waterproofing section within a surface steel formation, it is highly durable and has a long repair cycle. 【Features】 ■ Structural Characteristics... Double-sided tooth (double finger) structure, load-supporting type, non-drainage structure / T-shaped integral structure of cantilever beams ■ Durability... Eliminates the weak points of welded structures with stud welding of anchor bars, and the face plate and web plate are an integral T-shaped structure (shaped steel), ensuring high reliability with stud welding for anchor components, achieving durability ■ Rideability... Both the joint gap side and the post-poured concrete side are designed with tooth shapes to ensure excellent rideability / The protrusion length of the tooth shape on the face plate is also small, further reducing impact *For more details, please download the PDF or feel free to contact us.
