4. DU ANI’s technology

– Intellectual property rights retained (91cases)
– Weight reducing technology for aluminum structures
– Interpretation and design of extrusion of aluminum
– Precise machining and welding technology for aluminum materials
– Hybrid welding, bolting modularization
– Noise reducing technology for ships, cars, and architectural structures

: This platform safety device is installed to set apart the railway from the platform at subway stations or light railway transits so that noise, dust, and strong wind caused by moving rail motors are blocked and heating/cooling efficiency inside the stations is enhanced as well as the safety of passengers.

– Modularized processing method: Method of producing unit modules in the factory and carrying-in and installing on the spot
: Strengths of the method (reduction in air, efficient material and quality control, reduction in
construction cost, minimization of customers’ inconvenience while constructing)

– Weight reduction(reduced 20% compared to steel)
– Eco-friendly (100% recyclable)
– Labor reduction (AED method welding and assembling)
– Easy to design (good section design)
– Corrosion resistance
– Soundproof performance (structure-borne sound loss coefficient: over twice that of steel
or STS)

– Weight reduction : reduced 20~40% compared to steel frame
– Reduction in fuel consumption : enhanced fuel efficiency resulting from weight reduction
– Eco-friendly material : 100% recycling is possible
– Excellent absorption of Impact/vibration (compared to steel)

– A variety of designs by extrusion molding
– Various types of surface treatments
– Easy to assemble and construct
– Weight reduced and eco-friendly product

– Interior panel made with nonflammable and eco-friendly materials
– Blocks vibration/noise of ships and railroad vehicles, and avoids heat reserving effects and
dew condensation
– Modularized production per block units : reduction in construction labor
